IH-45 Traffic Conditions

Communication from UTMB Health

Aug. 26-29: Major closure of IH 45 in League City

TX-DOT announced some significant highway closures THIS WEEKEND in the League City area that could impact access to the UTMB Health League City Campus and other clinics in the region. The work will be concentrated on IH-45 between FM 518 and FM 517, and is scheduled to begin on Friday, Aug. 26 at 9 p.m. and conclude Monday, Aug. 29 at 5 a.m. 

The closures will enable a contractor to apply final striping on the southbound main lanes from south of FM 518 (in League City) to north of FM 517 (in Dickinson). It will affect travel lanes and entrance and exit ramps. Here's what's planned for this weekend: 

IH-45 Gulf Freeway:

  1. Alternating closure of two southbound main lanes from north of FM 518 to south of FM 517. No detour is required, as one southbound main lane will remain open, but slowdowns will be likely. 

  2. Total closure of the southbound main lane ENTRANCE ramps between FM 518 and FM 517. Detour – Motorists can enter the southbound mainlanes south of FM 517 using the entrance ramp from FM 517, but the feeder lanes in the area may be congested and slowdowns are likely.  

  3. Total closure of the southbound main lane EXIT ramps ramps between SH 96 and FM 517.
    Detour – Motorists can exit the main lanes using the southbound exit to SH 96 or the exit to Holland Road, as these will remain open.

Please check Transtar and other online traffic monitoring tools to plan accordingly and avoid slowdowns. As always, highway work is weather dependent and closures may be adjusted accordingly.
