Driving routes will soon change on the interchange at I-35 and US 183 in North Austin as the Texas Department of Transportation begins opening sections of a yearslong construction project.

The state agency announced April 22 it is opening two new flyovers connecting I-35 to US 183. On April 26, TxDOT is opening the southbound I-35 to northbound US 183 and southbound I-35 to southbound US 183 flyovers, weather permitting.

These ramp openings mark the first substantial milestone in the I-35 at US 183 flyover project. TxDOT broke ground on the $124 million project, which will deliver a total of four new or reconstructed ramps connecting the two major highways, in January 2018.

An hour before state crews open the new southbound I-35 flyovers, TxDOT will additionally close an existing ramp off northbound I-35 for a planned long-term closure.

The northbound I-35 to northbound US 183 ramp will close for the next four months as TxDOT crews reconstruct the ramp.


“We’re going to lessen the grade of that flyover to make it easier for traffic to climb it,” public information officer for TxDOT Diann Hodges said.

The state will close the ramp at 10 p.m. on April 26.

Vehicles wanting to enter northbound US 183 from northbound I-35 will have to take a detour using the Rundberg Lane exit, or exit 241 on I-35. The detour will take drivers around the U-turn at the Rundberg and I-35 intersection.

According to an April 22 TxDOT news release, this U-turn will be closed to local traffic in order to manage traffic flow.

Hodges said motorists taking the detour will have a dedicated ramp connecting the U-turn to the new flyover connected to northbound US 183.

“They will never encounter a signal,” Hodges said.

The state is currently working on the last new flyover at the interchange, which will connect northbound US 183 to northbound I-35. Hodges said TxDOT anticipates that flyover, the last substantial connection in this project, will open to traffic sometime this fall.
