Going to the Galleria this weekend will take a little longer if your trip includes southbound Loop 610.

Workers will close the southbound lanes at Woodway so crews can hang steel beams for a freeway overpass, according to the Texas Department of Transportation. The closing is scheduled from 9 p.m. on Friday to 5 a.m. Monday morning.

As a result, transportation officials are warning drivers to plan for slow traffic or choose another route. Police at the Woodway exit will manage traffic along the southbound frontage road, which can re-enter the southbound freeway at the entrance north of Post Oak Boulevard.

The overpass and other work along the freeway is related to a dedicated busway meant to speed trips from the Uptown area to Metropolitan Transit Authority’s transit center north of Interstate 10. The project, overseen by TxDOT, is expected to cost $57.2 million and open in 2020.

The bus lanes follow another project in the area, managed by the Uptown Houston Management District, that adds bus lanes to Post Oak. Combined, they will give buses the ability to bypass heavy traffic and use their own lanes from the transit center, south along Post Oak to Richmond.
