Winter weather on the same road? See the Interstate Weather Alerts. To plan the trip around delays, use the HOS Trip Planner, and check low bridges before you take a detour.

Data: state DOT work zone feeds in the Work Zone Data Exchange (WZDx) format, from the list in USDOT's WZDx Feed Registry. A zone is active when its start date has passed and its end date has not. Times are shown in your time zone. This is not a route plan and does not say if a road is open. Feeds can be late or miss jobs, and a limit not listed does not mean there is none. Read the posted signs and check the state 511 site.

Numbers tight? Let a dispatcher find better loads.

This tool is free. If it shows you are leaving money on the road, Grow Trucking finds loads, negotiates rates and does the paperwork for owner-operators and small fleets.

How do you find work zones on your route?

Search by interstate, state or place. The Work Zone Finder reads state DOT feeds in the USDOT WZDx format and lists each active or upcoming zone with its road, direction, dates, lane impact, speed limit and posted height, weight and length limits. It covers the states with a free public feed and says which states it could not read.

  1. Choose an interstate, a state, or a place and a distance.
  2. Choose how many days ahead to include work that has not started yet.
  3. Read the counts: zones active now, lanes affected, and truck limits posted.
  4. Check which states were read and which were not.
  5. Filter to active zones, lane closures or truck limits, then read each zone.
  6. Check the 511 site of any state that was not read, and read the posted signs.
What is shown for each work zone
ItemWhat it means
Active or starting soonActive: the start date has passed and the end date has not. Starting soon: it starts within the days you chose
Lanes affectedThe feed reports some or all lanes closed, alternating traffic, flaggers or a signal
Truck limitA height, weight, axle, length or no-trucks limit, or a width of 10 feet or less
WhereCross streets or mile markers from the feed
Speed limitThe reduced limit in the zone, when the feed gives one
Source and update timeThe agency and when the zone was last updated

Data is read from state DOT work zone feeds listed in USDOT's Work Zone Data Feed Registry on data.transportation.gov (read September 26, 2026). Feeds that need no key are used, plus Colorado's, Ohio's and the California Bay Area's, which are free with a key from the agency. The California feed covers the Bay Area only and mostly local streets. A feed not updated in 3 days is hidden. Feeds can be late or miss short jobs, and a limit that is not listed does not mean there is none. Interstates are matched from road names; Missouri names roads in a way that cannot be matched to interstates yet, so it shows in state searches only. This is not a route plan and does not say if a road is open.

Frequently Asked Questions - Work Zone Finder

How do I check for road construction on my route before a trip?
Pick your interstate, a state, or a place in this tool. It reads the state DOT work zone feeds and lists what is active now and what starts in the next 7, 14 or 30 days, with the lanes affected and any posted limits. Then check the state's 511 site for the states it could not read, and read the signs on the road.
Which states does the Work Zone Finder cover?
Only states whose work zone feed the tool can read: Arizona, California (San Francisco Bay Area only), Colorado, Delaware, Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Minnesota, Mississippi, Missouri, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Utah, Vermont, Maine, Washington and Wisconsin. Most of these feeds are free to anyone. Colorado, Ohio and the California Bay Area feeds are free with a key from the agency. A state whose feed is down, out of date or needs a key is shown as not read, not as having no road work.
What does WZDx mean?
WZDx is the Work Zone Data Exchange, a USDOT standard for sharing road work data. State DOTs publish feeds in that format, and USDOT keeps a registry of them. This tool reads those feeds. It does not use a private data source.
Does it show height, weight and width limits in a work zone?
Yes, when the state publishes them. Limits show in feet and inches or pounds. A limit that a feed leaves out is not shown, so a zone with no limit listed may still have one. Always read the posted signs. Some feeds fill unused limits with zero. The tool ignores those zeros instead of showing a 0 ft height limit.
How current is the work zone data?
The tool keeps each feed for up to 10 minutes and shows the time each zone was last updated. A feed that has not updated in 3 days is treated as out of date and its zones are hidden. Feeds can lag the road, so a short job may not be listed yet.
What does lanes affected mean?
The feed says traffic is changed: some lanes closed, all lanes closed, one lane alternating, flaggers, or a temporary signal. When the feed lists the lanes, the tool also shows how many are closed, like 1 of 2 lanes. If a feed does not say how traffic is affected, the tool shows impact not stated.
How dangerous are work zones for trucks?
FHWA reports that in 2022, 248 of the 821 fatal work zone crashes, or 30.2 percent, involved a large truck or bus. On rural interstates, more than 57 percent of fatal work zone crashes involved one. FHWA's advice for commercial drivers includes slowing down and staying informed about upcoming work zones, detours and restrictions.
Can a speeding ticket in a work zone hurt my CDL?
It can. Under 49 CFR 383.51, speeding 15 mph or more over the limit is a serious traffic violation, and serious violations can lead to a CDL disqualification that depends on your record. Fines and rules for work zones also differ by state, so check the state you are driving in.
Why does a state say no free feed, feed did not answer, or needs a key?
No free feed means the state does not list a public work zone feed with no key. Did not answer means the feed was down when you searched. Needs a key means the state offers the feed only to registered users. These states are listed so you know to check their 511 site.
