The three flyovers—also called overpasses—will ease traffic at the I-35 and US 183 interchange.
Construction for the project included a southbound I-35 flyover to northbound US 183, a southbound I-35 flyover to southbound US 183 and a northbound US 183 flyover to northbound I-35. Extensive construction was also completed at the existing flyover from northbound 1-35 to northbound US 183 and on the St. Johns Avenue bridge.
Construction of the $124.2 million project began in January 2018 and was completed in August. The project was funded by the TxDOT Texas Clear Lanes Congestion Relief Initiative.
The project was completed in an effort to address Texas’ most congested points. Prior to construction, the I-35 and US 183 interchange was ranked No. 41 out of the 100 most congested points in the state.
“The population of Texas has grown by almost the entire state of Oklahoma just in the last decade,” Texas Transportation Commission Chair J. Bruce Bugg Jr. said at the groundbreaking. “ When you have that kind of population growth in Texas ... we have to think about how we create transportation solutions.”
Bugg added that while Austin’s population continues to boom, the capacity of state highways has only grown 19%.
“As Central Texas continues to grow, the I-35 and US 183 interchange is key to moving people and goods throughout the region,” TxDOT Austin District Engineer Tucker Ferguson said in a news release. “The new flyovers ensure better connectivity between the highways and significantly improve mobility for commuters.”
