TxDOT will temporarily close the southbound main lanes of IH 45 in Huntsville tonight, weather permitting. The closure is needed to safely hang beams for the new Smither Drive bridges over IH 45.
The closure will begin at 8 p.m. and conclude by 5 a.m. the following morning. During the closure, all southbound IH 45 main lane traffic will be detoured to the IH 45 frontage road at Exit 115 and will be able to re-enter IH 45 at the entrance across from Huntsville Memorial Hospital.
Law enforcement officers will be on site to help guide motorist safely through the detour. TxDOT urges drivers to plan ahead and exercise caution through the detour area.
This is part of the $200 million reconstruction of IH 45 that involves replacing the four-lane freeway with a six-lane freeway with concrete media in Walker County. The project is anticipated to be completed in fall 2027.
