Environmental Assessment (EA)

CTRMA Bergstrom Expressway


On Friday, March 6, 2015, the Texas Department of Transportation cleared the way for the 183 South Project to proceed into final design and construction. In accordance with state and federal regulations, TxDOT issued a “finding of no significant impact”, or FONSI. It is a public decision document that briefly describes why the project will not have any significant environmental effect, and it also confirms the selection of the proposed tolled expressway presented in the final Environmental Assessment (see below) as the Build Alternative.

The environmental review, consultation, and other actions required by applicable Federal environmental laws for this project are being, or have been, carried-out by TxDOT pursuant to 23 U.S.C. 327 and a Memorandum of Understanding dated December 16, 2014, and executed by FHWA and TxDOT.


On November 19, 2014, the Federal Highway Administration (FHWA), and the Texas Department of Transportation (TxDOT) conducted a public hearing to discuss plans to improve US 183 between US 290 and SH 71 in Travis County (the Bergstrom Expressway). The Environmental Assessment (EA) as well as the public hearing summary and analysis, comment response report, and transcript are available for download and review.

The project limits extend from US 290 to SH 71, a distance of approximately eight miles. The purpose of the project is to improve system connectivity, local mobility, and travel times, while providing an efficient alternative route to congested local roadways in eastern Travis County. The social, economic, and environmental impacts of the project have been analyzed in the EA. The EA includes an assessment of the build alternative and the no build alternative and identifies the build alternative as the preferred alternative. The roadway would have six tolled main lanes and four to six non-tolled general purpose lanes (two to three in each direction). The preferred alternative includes a 10-foot-wide bicycle and pedestrian shared-use path, sidewalks, and bike lanes in the outer general purpose lanes. Approximately 4 acres of additional right-of-way and 9 acres of easements would need to be purchased for the proposed improvements to US 183.
