    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.

    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.
