Notice of Availability - MoPac (Loop 1) Finding of No Significant Impact

Purpose: TxDOT is advising the public of the availability of the Finding of No Significant Impact (FONSI) for the proposed MoPac (Loop 1) intersections project from north of Slaughter Lane to south of La Crosse Avenue in Travis County, Texas.
Description: The proposed improvements will involve grade-separating the cross streets of Slaughter Lane and La Crosse Avenue such that MoPac will pass under the existing cross streets. Traffic traveling northbound and southbound in this corridor will no longer need to stop at a signalized intersection to travel through the area. The proposed improvements to MoPac consist of two 12-foot lanes with one auxiliary lane in each direction, and 10-foot outside shoulders and 4-foot inside shoulders in each direction. The construction limits extend from approximately 2,500 feet north of Slaughter Lane to approximately 3,700 feet south of La Crosse Avenue, which results in a total project length of 2.07 miles. The construction limits allow the intersection improvements to tie back into the existing MoPac facility north of Slaughter Lane and south of La Crosse Avenue. The proposed improvements will be constructed within existing right of way.

Copies of the FONSI, approved Environmental Assessment (EA), and Public Hearing Summary and Analysis Report are available for public inspection and reproduction at the Central Texas Regional Mobility Authority:
