Lane closures on I-35 will be in effect just north of Williams Drive in Georgetown during the overnight hours Sept. 7-10, weather permitting, a news release from the city said. The closure is to allow construction work on the center support structure for the Northwest Boulevard bridge project.

The Northwest Boulevard bridge will be a new east-west connection over the interstate and an alternative to Williams Drive, the release said. The project connects Rivery Boulevard to the west and FM 971 to the east and is scheduled to be complete in early 2021.

Closure of one northbound main lane and two southbound main lanes on I-35 will be in effect from 9 p.m.-5 a.m. starting each evening Sept. 7-10.
