The southbound I-45 traffic south of Park Road 40 will be shifted from the existing southbound lanes into the newly constructed lanes in the median, beginning Wednesday night, March 6. Traffic shift is weather dependent, if the weather is not favorable for traffic switch this week, this operation will occur on a later date. Traffic will travel on the middle portion of the newly constructed FM 1374 bridge overpass and merge back to the existing southbound lanes just south side of FM 1374 bridge. Traffic configuration will be two 12 foot lanes with 2 foot inside shoulder and 9 foot outside shoulder contained within the concrete barrier. Drivers should reduce speed and maintain safe traveling distances between vehicles.
Southbound I-45 traffic will remain in this location until the existing southbound lanes are constructed into three lanes of concrete pavement.
I-45 will be reconstructed to pass over local roads (including FM 1374 and FM 1375) to increase public safety by reducing any interference with I-45 traffic due to future bridge maintenance and to eliminate the damage caused by over-height loads.
To alert drivers to the lane closures, changeable message signs will be placed near the northbound and southbound lanes of I-45 beginning one week before the traffic switch. The speed limit is reduced to 65 MPH throughout the limits of the project.
The I-45 lane closures are part of the reconstruction of IH 45 that will involve replacing the existing four-lane divided highway with a six-lane highway with a concreted median barrier in southern Walker County. The project is scheduled to be completed in September 2021.
During the 4.5-year project, multiple lane shifts and relocation of traffic will take place at various times to accommodate construction activity.
