Beginning at 10 p.m. Dec. 2, the Texas Department of Transportation will close several I-35 main lanes between US 183 and Rundberg Lane in North Austin.

All northbound I-35 main lanes will be closed from 10 p.m. Dec. 2-5 a.m. Dec. 3 as construction crews remove an overhead sign bridge and set high mast lighting poles, weather permitting, according to a TxDOT news release. The work is part of the $124.2 million project to improve I-35 between Rundberg and Hwy. 290 and add three flyovers to connect I-35 and US 183.

During construction, northbound vehicles will be detoured to the frontage road at Rundberg Lane and can enter I-35 at the next entrance ramp before Rundberg Lane.

TxDOT will reduced southbound I-35 traffic to two lanes during that work. According to TxDOT, southbound drivers can expect lane reductions and one rolling lane closure between 10 p.m. Dec. 2 and 1 a.m. Dec. 3

All lanes will reopen to traffic once work is completed. TxDOT in its news release stated work will finish no later than 5 a.m. Dec. 3.
