As a part of mobility improvements on Spicewood Springs Road, the city of Austin will rehabilitate a wastewater pipe near the end of its service life.

According to a press release from the city, the pipe crosses underneath parkland between Spicewood Springs Road and North Capital of Texas Hwy.

Instead of implementing a new pipe, “Austin Water has proposed rehabilitating the pipe by inserting a liner between two manholes,” according to the press release. The decision will allow the city to avoid an excavation project that could affect parkland.

The liner will “restore structural integrity, reduce infiltration, eliminate leaking joints and improve water quality,” said Jack Flagler, public information specialist with the Austin Transportation Department.

The project will require the city to use the parking lot shown below for one month. The public can provide feedback on the use of that parking lot by emailing [email protected] before staff makes its request for temporary parkland use at the parks and recreation board meeting Sept. 28.

According to the press release, the Spicewood Springs project will widen Spicewood Springs Road between North Capital of Texas Hwy. and 0.2 miles west of Mesa Drive to two lanes in each direction. It will also include a new raised median with left-turn bays and shared use paths on both sides of the road.

Construction for the project is expected to run from early 2022-24, with the wastewater rehabilitation project taking place during that time period, Flagler said. The installation of the liner requires a two-week period when little rain is anticipated, he added.

The project includes $17 million in funding from the city's 2016 mobility bond. For more details on the project, visit the Regional Mobility Project website.
