(Previous notification 3/20/2025):
WEBSTER PARISH – The Louisiana Department of Transportation and Development advises motorists that the $19.3 million project to replace the LA 531 overpass over I-20 near Minden in Webster Parish is moving closer to completion.
Major construction on the new LA 531 overpass is now complete, and the contractor is preparing to swap traffic onto the newly built bridge.
On the nights of March 25-29, 2025, I-20 eastbound and westbound at the LA 531 interchange will be closed. These nighttime closures are scheduled to take place from approximately 7:00 p.m. to 6:00 a.m. each night, and is necessary to allow the contractor demolish and remove the old bridge.
Through traffic on I-20 will be detoured on to and off the LA 531 ramps during these closures. This will allow the contractor to safely conduct the bridge removal operations.
Other current work includes the construction of the two roundabouts that are taking shape at the on and off-ramps and will replace the stop sign controlled intersection. These roundabouts will allow for a much safer and more efficient traffic flow as drivers enter and exit the interstate and turn onto LA 531.
The entire project is anticipated to wrap up in early Summer 2025, with progress dependent on weather conditions and other factors that can impact construction timelines.
The LA 531 corridor at I-20 is home to several truck stops and services about 9,000 vehicles per day. This infrastructure investment will ensure continued connectivity for both residents and businesses who utilize this route on a daily basis.
