AUSTIN (KXAN) — While two newly-constructed flyovers are opening Sunday at the I-35/U.S. 183 interchange, one existing flyover will be closing for at least a few months for reconstruction.
The Texas Department of Transportation said the existing northbound I-35 to northbound U.S. 183 flyover will shut down for about four months, beginning 10 p.m. Sunday. Crews will demolish and reconstruct one portion of the flyover.
A long-term detour will be put in place. Drivers looking to use that flyover will instead be directed to the Rundberg Lane exit (#241) to take a U-turn at Rundberg Lane and transfer onto the new southbound I-35 to northbound U.S. 183 flyover. The U-turn at Rundberg Lane will also be closed to local traffic to manage the flow of cars, TxDOT said.
TxDOT put out the below YouTube video to explain the detour.
On Sunday at 11 p.m., TxDOT is planning to open the new southbound I-35 to northbound U.S. 183 and southbound I-35 to southbound U.S. 183 flyovers.
TxDOT said this is a “significant milestone” in the project that’s expected to add three new flyovers total to the interchange.
