The Texas Department of Transportation will be closing part of I-35 on Thursday night and a section of US 183 on Monday night in the Austin area to allow crews to remove overhead signs.

The state agency is in the midst of several construction projects along I-35 in Central Texas. At Oltorf Street in South Austin, TxDOT is reconstructing the bridge and improving the interchange south of Woodland Avenue to Woodward Street, according to TxDOT. Work includes improving entrance and exit lanes and ramps as well as adding U-turns at Oltorf.

At the US 183 interchange in North Austin, the state agency is adding three direct connect flyovers between I-35 and US 183. Other work includes rebuilding the St. Johns Avenue bridge, adding frontage road U-turns and adding bypass lanes so drivers can avoid the traffic signal at St. Johns, according to TxDOT.

TxDOT released information Wednesday on the overnight closures on I-35 and US 183:
