The Texas Department of Transportation announced Jan. 27 it plans to spend $1.3 billion on the state’s most congested roadways, including I-35 in Travis County.

About $158.6 million will go toward projects in TxDOT’s Austin District, including at 51st Street, Oltorf Street and between Rundberg Lane and Hwy. 290 E. The congestion relief plan still needs approval from TxDOT’s governing board, the Texas Transportation Commission, which likely will take a vote at its Feb 25 meeting.

“Relieving traffic congestion is essential for our economy and our quality of life,” state Sen. Kirk Watson, D-Austin, said in a news release. “I’m pleased this initiative has put the emphasis on I-35, which is the most pressing congestion problem for Central Texas as well as the state. We’ve worked hard and successfully to develop a plan for reducing congestion on I-35 and this investment is key to moving that plan forward.”

In recent years TxDOT has received more funding to put toward making improvements on I-35. The agency’s $4.3 billion Mobility35 implementation plan involves breaking down the plan into manageable projects that can be funded as money becomes available.

“We are so grateful in Central Texas for our governor and the commission’s interest in congestion relief. We are especially appreciative that Commissioner [J. Bruce Bugg Jr.] has spent so much time with us locally listening to the concerns of our region,” said Will Conley, chairman of the CAMPO policy board and Hays County Precinct 3 commissioner. “This correspondence has strengthened our partnership with the state and strong partnerships make it possible to effectively and efficiently meet the needs of our citizens.”

TxDOT has already allocated $58.7 million toward the four projects in the congestion relief plan. Those projects will cost a total of $387.3 million.
