Please be advised that TxDOT will be performing a total closure of I-45 this Saturday morning to set the remaining 2 overhead large sign structures on the project both near the SH 96 overpass. This work will include a total NBML closure on Saturday from 6AM to noon and a short term total closure SBML only when setting the structures.
We will also be switching NBML traffic to the permanent configuration from north of FM 517 to north of SH 96 this weekend. This work will be performed beginning Friday at 9PM through Monday at 5AM including an alternating NBML 2 lane closure from FM 517 to north of SH 96 and closure of the following ramps:
NB FM 518 exit
NB FM 646 entrance
NB SH 96 exit
NB FM 517 entrance
The NB FM 646 exit ramp will remain all weekend. This will serve as the exit during the total closure and the detour for the SH 96 and FM 518 exits all weekend during the traffic switch. The SH 96 entrance ramp will also remain open all weekend for traffic to re-enter the NBML. SBML traffic will exit to SH 96 during the short-term total closure and be able to re-enter via the SH 96 entrance ramp. We will also have off-duty officers assisting with keeping traffic flowing at the FM 517, FM 646, and SH 96 intersections.
Travelers should avoid this area if possible and expect delays in this area as there is a high likelihood of increased traffic and congestion during this project.
