Mobility Authority Awards Design-Bid-Build Contract for 183A Phase III Project

The Central Texas Regional Mobility Authority’s Board of Directors on Wednesday unanimously voted to award a $175.7 million design-bid-build contract for the 183A Phase III Project to The Lane Construction Corporation. A U.S. subsidiary of the global construction leader Webuild, The Lane Construction Corporation specializes in highway and bridge construction.

The 183A Phase III Project consists of a 6.6-mile extension of the 183A Toll Road from Hero Way to just north of SH 29 in south-western Williamson County. The project will include the addition of two tolled lanes in each direction and significant non-tolled improvements, including a shared use path from Hero Way to the proposed Seward Junction Loop project. The project will also feature landscaping and other aesthetic enhancements along the corridor – a vision developed through an extensive 16-month public input process led by the Mobility Authority and the Texas Department of Transportation (TxDOT).

Cleared last year by TxDOT’s Environmental Division to move into the final design and construction phase, the project will help improve mobility throughout the congested US 183 corridor.

“What we’re seeing is increased traffic and unimpeded growth throughout Williamson County,” said Mike Heiligenstein, Executive Director for the Mobility Authority. “This project is a huge opportunity to not only relieve roadway congestion but to enhance safety along the corridor at key interchanges like SH 29, by separating high-speed through traffic from local traffic.”

The Mobility Authority received four responsible and responsive bids from prequalified bidders, which were evaluated based on their price proposals against the Engineer’s Estimate of $174.6 million. The Board of Directors unanimously approved a motion to award the contract to the lowest responsive and responsible bidder— The Lane Construction Corporation, for $175.7 million. The project will not use state funds but rather will be financed by the Mobility Authority using available and flexible funding mechanisms such as the sale of toll revenue bonds.

Contract award and execution is conditioned upon receiving final concurrence from TxDOT.

The project will be constructed in phases and in coordination with construction north of TxDOT’s US 183 general purpose lane extension. Total project cost is $277.3 million. Roadway construction is expected to begin April 2021.

“This project will have positive far-reaching benefits for this fast-growing area of Williamson County,” said Heiligenstein. “Making for a safer, more mobile Central Texas.”
