For a U.S. trip, start with the Federal Highway Administration’s National Traffic and Road Closure Information directory. Select your state or territory, open its official traveler-information service, and check the map or alerts for construction, closures, incidents, and detour routes. Then verify the exact road, direction, travel date and time. If the street is city- or county-maintained, check that agency’s project page too, because state and regional feeds do not always include every local road.
Check before leaving. If you need an update while already traveling, use a voice service or pull over before handling a phone.

Start with the official road-information source
Road-closure information is organized by the agency that owns or manages the road. A state highway, county route and city street may therefore appear in different systems. The most reliable starting point for a U.S. journey is the Federal Highway Administration’s national directory, which points travelers to official state and territorial traffic-information sources. The directory was displaying a last-updated date of April 20, 2026 when checked.

The FHWA page is a directory, not a live national map. Its purpose is to get you to the transportation department or traveler-information service responsible for the jurisdiction you need.

1. Find your state or territory
- Open the Federal Highway Administration’s National Traffic and Road Closure Information directory.
- Select the state or territory where your trip will occur.
- Follow the listed transportation department or traveler-information link. The directory is a way to reach the responsible service; it is not one nationwide live map containing every local closure.
For a trip crossing state lines, repeat this step for every state or territory on the route. A closure near an interchange or border can affect your approach from the next jurisdiction, and one state’s map does not establish what the neighboring state is reporting.
2. Open the state or regional traveler-information service
Many departments use a 511-branded service, although the name and available channels differ. Depending on the location, the service may provide a web map, mobile app, route or text alerts, social updates and a telephone line. A Florida FL511 description, for example, includes construction, closures and detour routes across those channels. Do not assume another state offers exactly the same layers or alert options.
“511” is a useful search term, not a promise of identical coverage. Search the state or region name plus “511,” “traffic,” or “road closures” if the directory link is difficult to locate. Use the agency link reached through the FHWA directory when possible, so a search result does not lead you to an outdated or unofficial page.

Enter the highway, street, city or destination when the service supports search. Zoom to the portion of the route you will actually use and enable construction, closure, incident and detour layers where available. Open each marker or alert instead of relying only on its icon. The detail can identify the affected segment, direction, timing, reason and any suggested route.
Some services separate planned construction from active incidents. Read the legend and the alert text, and do not treat a construction symbol as proof that all lanes are closed. A project can involve a shoulder, a single lane, overnight work or a full detour at different times.
Know which source answers which question
Use the source with authority over the road, then use other channels to fill gaps. This hierarchy prevents a general map from being mistaken for a complete project notice.
| Source | What it can establish | Important limitation |
|---|---|---|
| FHWA national directory | Where to find official state and territorial traveler-information services | It is a directory, not a single nationwide live closure map |
| State or regional 511 service | Potentially current maps, route alerts, construction notices, closures, detour routes, cameras and telephone access | Coverage, layers and alert channels vary by provider |
| City or county transportation/public works agency | Project notices and restrictions for a particular municipal or county-maintained street | A statewide or regional feed may omit a local road or project |
| Navigation app | An additional indication that a route may be slow, blocked or changing | The reviewed sources do not establish any particular app’s accuracy, completeness or update interval |
The road owner’s notice is especially important when you need a project limit, a detour diagram, a bridge restriction or a schedule for a named street. A navigation app can help you notice a possible problem, but it does not replace confirmation from the responsible agency when the restriction matters to a delivery, appointment, emergency access or other consequential trip.
Check local streets separately
If the closure is on a neighborhood street, county road or a named construction project, go beyond the state map. Search for the responsible city transportation department, county public works department or the project’s official notice. Look for a project page, construction bulletin, detour diagram, lane-closure notice or public works alert.
Local coverage matters even when a road appears near a state route. A regional FAQ reviewed for this guidance notes that 511 information varies by provider. A state service may show a major highway closure while leaving a nearby municipal restriction to the city’s own notice system. When the street name, project limits or detour is important to your trip, the road owner’s notice has the strongest authority.
Identify the road owner
- Interstate and major state routes are usually covered by the state transportation department or its 511 service.
- County routes and bridges may be managed by a county transportation or public works agency.
- Residential streets, downtown blocks and city projects generally belong to a municipal transportation or public works department.
- A private development, utility project or event may publish a separate traffic notice; check whether the public agency has adopted or referenced it.
When you are unsure who owns a road, note the route number, street name and nearest cross streets, then search those details with “transportation,” “public works” or “closure.” Confirm the agency’s jurisdiction on its own page rather than assuming that the closest city controls a county road.

Read a closure or detour notice precisely
A marker labeled “construction” does not necessarily mean the road is closed. Before changing your route, open the details and distinguish among planned work, an active closure, a lane restriction, an incident and a posted detour.
Confirm the roadway and direction
Match the notice to the exact route number or street name, the cross streets or milepoints, and your direction of travel. A closure on eastbound lanes may leave westbound lanes open; a bridge restriction may apply only between stated intersections. If the map uses separate symbols, use the legend. The Bay Area traveler-information service, for example, distinguishes construction icons from closure icons and allows details to be opened from the map or alerts area.
Do not rely on a place name alone. Two roads can share a name, and a project can affect only one ramp, frontage road or segment. Check whether the alert names an entrance, exit, interchange, bridge, lane or shoulder that matches your itinerary.
Confirm when it applies
Read the start and end dates, daily hours, weekends, overnight periods and any “until further notice” language. A planned nighttime lane closure is different from a full-day detour. Recheck close to departure because active road status can change after the original notice is posted.
Compare the notice’s publication or revision time with your planned departure. A future work notice may not describe the conditions during today’s commute, while an incident alert can change quickly. If an end date has passed but the road still appears restricted, look for a newer bulletin or an active alert instead of assuming the project is complete.
Recommended Free Tools
Follow the stated detour
When an agency publishes a detour route, compare it with your destination and vehicle needs. A detour may use a road unsuitable for a large vehicle, have its own construction, or add time during peak traffic. If no official detour is shown, do not infer that a nearby side street is approved; use the agency’s alternate route or contact information.
Check every turn in a long detour, not just its first instruction. A detour can leave the closed segment and rejoin the original route farther downstream. If the notice provides a diagram, retain it for reference before departing and verify that any alternate road is open to your direction of travel.
Use maps, alerts, apps and phone access together
Different channels serve different planning moments. A web map is useful for examining a route and nearby projects. An app may provide push notifications or saved routes where the local provider supports them. Text or route alerts can warn you about a recurring commute. Social updates may explain a sudden change, while a telephone or 511 voice service is useful when you cannot safely look at a screen.
Feature sets are not uniform. Before depending on an alert, check what the local service actually offers, whether you must create a route or account, and which roads are included. An alert that covers a state highway may not include a city street. Cameras can show conditions at a point in time, but a camera view does not replace a closure notice or detour instruction.

Pick the symptom - the matching free tool is one click away.
Use more than one channel when the trip is important: review the map, read the detailed alert, and check a local project notice if the road is locally maintained. Agreement between channels is helpful, but the key test remains whether the source has authority for the exact segment and direction.

A reliable pre-departure workflow
Use this sequence for a commute, appointment, delivery or longer trip.
- Define the trip. Write down the route, direction, entry and exit points, departure time and any time-critical arrival.
- Locate the official source. Use the FHWA directory to reach the state or territorial transportation service.
- Search the route. Turn on construction, closure, incident and detour layers, then open each relevant alert.
- Check local agencies. For city or county roads, review the responsible transportation or public works project page and notice.
- Compare details. Confirm the road, direction, limits, dates, hours and detour against your planned trip.
- Save the information safely. Note the detour or enable an available route alert before leaving, rather than trying to read while moving.
- Recheck near departure. Verify the notice again because roadwork and incident conditions are volatile.
- Allow a fallback. If the route is uncertain, identify a second official route or leave extra time without assuming the restriction will clear.
For a multi-day trip, repeat the check on each travel day. A project’s planned schedule can change, and an unrelated crash, weather event or emergency closure can affect the same corridor after you have completed your initial planning.
How to handle conflicting or missing information
The state map shows nothing, but a local notice exists
Give the local road owner’s notice priority for that street. Keep the project page or notice details available, and check whether the regional service lists the project under a different road name, route number or jurisdiction.
A missing statewide marker does not prove that the local closure is cancelled. Confirm the exact project limits and dates on the municipal or county page, and use the local agency’s contact or telephone traveler-information option when the restriction is critical.
A navigation app shows a blockage that the agency does not list
Treat the app as a supplementary warning. Check the state, regional or local agency for confirmation of the exact restriction, direction and timing. The available evidence does not establish a universal accuracy or update interval for commercial navigation apps, so do not use an unverified app report as the sole basis for a consequential trip.
The notice is old or lacks a clear end time
Look for a newer alert, project bulletin or agency update. Compare the notice’s publication or revision time with your departure. If the restriction affects a critical journey and the service provides a phone line, use it for clarification rather than assuming the work is finished.
Two official pages disagree
Check which agency owns the road and whether one page describes planned work while the other reports an active incident. Note the most recent update and the exact segment. If the conflict remains, contact the responsible agency or use its telephone traveler-information service before departure.

Return to the FHWA directory and try the state or territory’s transportation department link rather than relying on a general web search. Some providers use a different traveler-information name or offer a map and telephone line without prominent 511 branding. For a local street, go directly to the city or county transportation/public works site.
Safety while checking updates
Do not handle or inspect a phone while driving. Check the map and notices before leaving. If conditions change en route, use a 511 voice service where available, ask a passenger to check, or pull over in a legal, safe location before using a smartphone. A detour is not useful if reading it creates a crash risk.
Set up route or text alerts while parked, and silence or manage notifications before moving if they could tempt you to interact with the phone. A passenger can read an update, but the driver should remain focused on traffic and posted signs. Follow temporary signs and directions from law enforcement or roadway workers even when an online map appears different.

What federal timing benchmarks do—and do not—mean
U.S. federal regulations provide limited reporting benchmarks for certain traffic-management information. In the 2023 edition, roadway- or lane-blocking traffic incidents in metropolitan areas have a benchmark of 10 minutes or less after verification. Specified hazardous driving conditions and roadway or lane closures or blockages caused by adverse weather have a benchmark of 20 minutes or less after observation.
Those figures apply to the regulatory situations described, not to every construction notice, city project page or live map. They are not a guarantee that every agency’s roadwork feed will refresh within those intervals, and they do not establish an average freshness or accuracy rate for state and local services. A planned bridge project can have a different publication schedule from an unexpected crash or weather blockage.
Use the benchmarks as context for the kinds of incident reporting addressed by the regulation, not as a countdown timer for your own closure search. Always compare the notice’s actual update time and scope with your trip.
Examples of applying the process
Interstate trip across several states
Start with the FHWA directory and open each state’s official traveler-information service along the route. Search the interstate and direction in each system, then inspect construction and closure alerts near interchanges. Because a detour in one state can affect the next state’s approach, repeat the check for every jurisdiction rather than relying on one map.
Daily commute on a city street
Check the regional 511 service for incidents and major construction, then open the city transportation department’s project page for the street. Confirm the work hours and cross streets. Save a route alert if offered, and recheck before leaving on days when the project schedule changes.
County bridge or rural road
Use the state service first, but search the county public works site for bridge restrictions, washouts or local detours. Verify whether the notice applies to your vehicle type and direction. Rural coverage may be less detailed, so allow time to confirm the route before setting out.
Last-minute closure during travel
Do not stop in a travel lane to read an alert. Pull over safely or use a voice channel. Once stopped, identify the road owner, check the active closure and follow the published detour rather than selecting an unverified shortcut.
Planned overnight construction
Read the daily work window and determine whether your departure falls inside it. A project listed for nighttime hours may leave the road open during the day, while a weekend schedule can differ from weekday conditions. Recheck the notice on the day of travel for changes.
Choosing between available information sources
When several pages or alerts appear, compare them using five tests:

Frequently asked questions
Frequently Asked Questions
What is the best first place to check U.S. road closures?
Use the Federal Highway Administration’s National Traffic and Road Closure Information directory, select the state or territory, and open the linked official transportation or traveler-information service. It directs you to the responsible source but is not itself a nationwide live closure map.
Does every state have the same 511 features?
No. State and regional providers differ. One may offer a web map, app, text or route alerts, social updates, cameras and telephone access, while another may provide a different combination. Check the local service’s coverage and alert terms.
How do I find a closure on a city street?
Check the city transportation or public works department and search for the street name, project page, construction bulletin, detour diagram or lane-closure notice. A state or regional 511 feed may not include every municipal road.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteCan I rely on a navigation app alone?
Use it as an additional warning, not as the sole authority for a consequential trip. The available sources do not establish a universal accuracy, completeness or update interval for commercial navigation apps. Confirm the road, direction and timing with the responsible agency.
What details should I verify in a closure notice?
Match the route number or street, cross streets or milepoints, direction, affected segment, status, start and end dates, daily hours, and any official detour. Distinguish a lane restriction or planned work from a full closure.
How close to departure should I recheck?
Recheck near departure because construction, incidents and weather-related restrictions can change. Compare the notice’s latest publication or revision time with your planned travel time; there is no universal refresh interval for every service.
What should I do if two official sources disagree?
Determine which agency owns the road, compare the exact segment and update times, and see whether one page describes planned work while the other describes an active incident. If the conflict remains, contact the responsible agency or use its traveler-information telephone service.
What are the federal 10-minute and 20-minute figures?
The 2023 federal regulatory edition includes a benchmark of 10 minutes or less after verification for roadway- or lane-blocking traffic incidents in metropolitan areas, and 20 minutes or less after observation for specified hazardous conditions and weather-caused roadway or lane closures or blockages. These do not promise that every construction or local project notice updates within those periods.
How can I check a closure safely while already driving?
Do not inspect or handle a phone in motion. Use a 511 voice service where available, ask a passenger to check, or pull over legally and safely before viewing a map or notice. Follow posted signs and roadway-worker instructions.
The Bottom Line
Use the FHWA directory to reach your state or territory’s official 511 or traveler-information service, then check the responsible city or county agency for local roads. Match every notice to your route, direction and travel time, recheck just before departure, and never read a phone while driving.
