Notice of Availability of Finding of No Significant Impact (FONSI) for 183A PHASE III From Hero Way to SH 29


This notice advises the public that the Texas Department of Transportation (TxDOT) has issued a finding of no significant impact (FONSI) for the proposed extension of 183A from Hero Way to SH 29 in Williamson County, Texas.


The proposed 183A tollway project will have two tolled lanes in each direction to start and will be widened to three lanes in the future. The proposed tollway is planned to be located mostly in the existing right of way (ROW) within the median of the US 183 corridor. The extension will also feature a shared use path north from Hero Way to the proposed Seward Junction Loop project located just north of the existing Mourning Dove Lane.

The proposed Build Alternative would be constructed within the existing ROW of 183A and US 183 with the exception of additional ROW totaling approximately 19.3 acres near the northern portion of the project. The additional ROW is to provide sufficient area for constructing the transition to US 183 for approximately 1.1 miles north of SH 29. The proposed 183A facility would stay within the existing 183A and US 183 alignment and no new location roadways are proposed as part of the project. Although additional right of way is required, no residential or non-residential structures would be displaced.

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.
