Nightly total closures of the main southbound lanes of IH-45—from NASA 1 to FM 518 and SH 96—will begin on Tues., January 24, and run through Weds., February 8. The lanes will be closed from 9 p.m. to 5 a.m. on weekdays, and from 9 p.m. to 8 a.m. on weekends. Southbound IH-45 traffic will detour via the FM 518 exit and re-enter IH-45 via the entrance ramp south of FM 518.
To keep southbound feeder road traffic moving during the closures, there will also be nightly total closures of the FM 518 intersection at IH-45 for vehicles traversing on FM 518.
Construction crews will be working on the IH-45 bridge over Clear Creek, requiring the lane closures. All work and dates are weather permitting. Please see the TX-DOT website for updates, check traffic conditions online and adjust commute times as necessary.
