The Texas Department of Transportation on May 15 will finish the second of two legs of demolition on a ramp connecting I-35 to US 183 in North Austin.

Between 6-8 a.m. on May 15, TxDOT crews will close both directions of the I-35 and US 183 mainlanes and frontage roads at the intersection of I-35 at US 183 during the controlled implosions. The demolition will bring down sections of the existing northbound I-35 to northbound US 183 ramp.

Traffic will be stopped for about 20 minutes at a time during demolition procedures, TxDOT said in a May 13 news release.

TxDOT partnered with Make-A-Wish Central & South Texas to allow 6-year-old Archer, a local Leukemia survivor, to push the button to demolish parts of the northbound I-35 to northbound US 183 flyover.

The flyover demolition is part of a larger project to build four new or reconstructed flyovers connecting I-35 to US 183.

The northbound I-35 to northbound US 183 flyover is being demolished and reconstructed to reduce the incline on the ramp.

According to the state, the ramp was too steep and caused traffic—specifically large trucks—to slow down and delay traffic along I-35.

TxDOT states reconstruction of this ramp will take approximately four months to complete, weather permitting.

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, that U-turn will be closed to local traffic in order to manage traffic flow.
