AUSTIN (KXAN) — A new bicycle and pedestrian bridge that would run under MoPac South, between Loop 360 and Southwest Parkway, has hit a snag in construction. Project developers on Thursday asked Austin City Council to allot $1 million extra to fund the completion of the project, which they later approved.
The MoPac Mobility Bridge Project started in 2013 but ran into issues earlier this year when engineers tested the bedrock to determine if it would support the foundation. Those tests showed it to be two feet down. However, when crews started digging in that stretch of the Barton Creek Greenbelt, they discovered most of the bedrock was 18 feet down.
“That caused us to go back, redesign the foundations, work with the contractor to do that, and those changes resulted in an increased cost,” said Chad Crager, division manager with the Public Works Department.
The bridge will now cost an estimated $8.8 million.
It’s expected to be completed in March of next year. Also, part of the project includes restriping MoPac south of Loop 360 from two lanes to three.
