Speed Limits in Construction Zones 

Speed limits are substantially reduced in construction areas, both on and off of roadways. This is to ensure the safety of both motorists and construction crews. When approaching a construction zone, look for posted signage (similar to the picture above) which will specify the speed limit of that particular area. A typical speed reduction is 10 mph or more below the road's regular speed limit.

Missing Sign

To report a missing speed limit sign, please call the Public Works Traffic Division at (817) 748-8370 during business hours of 7:00 a.m. to 4:00 p.m. Monday through Friday. When reporting an issue, please provide a specific address or the appropriate cross streets.
