Approving a Weiss Lane Roadway Improvements Interlocal Agreement (ILA) with Travis County and authorizing the City Manager to execute same.
Summary
The current ILA was approved following the City's 2014 General Obligation bond election in November 2014 approving funds to collaborate with Travis County to construct Weiss Lane safety improvements. The scope included rehabilitation of the existing two lanes, the construction of 4-foot shoulders on both sides and left turn lanes at roadway intersections.

Ideally, it should be constructed with 3 lanes or to support future expansion to 3 lanes, but also include pedestrian facilities since the transportation plan shows Weiss Lane as a 6-lane corridor (ultimately).
In our meeting, these challenges were discussed and we mutually identified the fo...
