HOUSTON --Road crews are shutting down the mainlanes of Interstate 10 at Highway 99 this weekend so they can hang steel bridge girders of the planned Grand Parkway-Interstate 10 interchange. At 9pm Friday, all westbound lanes of the Katy Freeway, as well as the U-turn lane, were closed at the Grand Parkway exit. Drivers were detoured onto the westbound frontage road at the exit ramp for Texas 99 and re-entered I-10 westbound mainlanes after the signal via the next entrance ramp. That closure remained in effect until 11am Saturday, then authorities switched sides and shut down the eatbound lanes of I-10.
Drivers will be detoured to the eastbound frontage road at the Grand Parkway exit ramp until they pass the construction.The closure is expected to remain in effect until 5am Monday.
