About this project

Summary of work

  • Replacement of the bridge on 11th Drive over I-90 in Austin.  Work includes grading, paving, bridge replacement, shared use trail and drainage improvements.  The new bridge will be widened to accommodate two 12-foot lanes, two 8-foot shoulders and 10-foot sidewalk.  The existing roadway alignment will remain the same. I-90 will remain open except when existing bridge is demolished and bridge beams are set. During those closures, traffic will be routed up and down the ramps on I-90. The bridge crossing will be closed and detoured for the duration of the project.

Cost

  • $2.97 million
