The main lanes of Tomball Tollway and the eastbound lanes of the Grand Parkway will be closed nightly from Sept. 15-22, according to the Harris County Toll Roll Authority.

The closures will affect the main lanes of the Tomball Tollway—the tolled portion of Hwy. 249—between Boudreaux Road and the Grand Parkway; the eastbound Grand Parkway main lanes from the Rocky Road exit ramp to the Boudreaux Road exit ramp; and the northbound entrance ramp from Northpointe Boulevard and the southbound Holderrieth Road entrance ramp on the Tomball Tollway.

These roads and ramps will be closed nightly beginning at 9 p.m. Sept. 15 through 5 a.m. Sept. 22, according to the HCTRA.

Northbound drivers traveling on the Tomball Tollway can detour by taking the frontage road at the Boudreaux Road exit ramp and re-enter the tollway at the Grand Parkway entrance ramp, while southbound drivers can take the frontage road at the Grand Parkway exit ramp and re-enter the tollway at the Northpointe entrance ramp.

Drivers on the eastbound lanes of the Grand Parkway can detour by taking the frontage road at the Rocky Road exit ramp, turning right onto the southbound Hwy. 249 frontage road, turning left at Boudreaux Road and then turning left onto the northbound Hwy. 249 frontage road, which will return drivers to the eastbound Grand Parkway frontage road.
