Multiple lane closures along I-35 set for this weekend

AUSTIN, Texas - Drivers should prepare for lane closures and detours this weekend while TxDOT crews are working at multiple locations along I-35.

Closures are set in four locations across Travis, Hays, and Williamson counties. TxDOT says most closures will have a minimal impact on the I-35 mainlanes.

This closure is set to begin at 9 p.m. Friday, Dec. 15 and last through 1 p.m. Saturday Dec. 16.

The Williams Drive bridge in Georgetown will close as crews prepare to open the new diverging diamond interchange (DDI).

The bridge will then close again at 9 p.m., Dec. 16, and remain closed overnight until 10 a.m. Dec. 17 for final preparations for the new DDI.

According to TxDOT, a DDI is an "innovative design" that addresses congestion by allowing vehicles to travel more quickly through busy intersections and is particularly effective at locations with a high volume of left-turning traffic. 

A DDI increases traffic flow by temporarily shifting traffic to the left side of the roadway, allowing through-traffic and left-turning traffic to proceed through the exchange simultaneously, eliminating the need for left-turn signals, according to TxDOT.
