What's Happening Now

On March 5, 2015, the Texas Department of Transportation issued a Record of Decision (ROD) which allowed the SH 45SW project to proceed to final design and construction, with specific commitments to protect the environment during construction and operation of the roadway.

Agency Roles

Mobility Authority logo The Mobility Authority will design, construct, operate and maintain SH 45SW.


TxDOT logoTxDOT was the lead agency in the development of the SH 45SW environmental study, including related environmental documentation and coordination of public outreach.


The Process

Prior to development of final design plans, the Mobility Authority will collect additional field surveys, obtain geotechnical information and review and refine the schematic that was developed during the environmental phase. During this process, the Mobility Authority may identify a design change that would benefit the project by reducing the impact to environment, improving operations, or increasing safety.

When the final design process is complete, the project team will release the plans for bid by construction contractors.

What's Next?

The development of the construction plans will take several months. Before construction begins, the Mobility Authority will "let" the project by releasing the plans and requesting bids. The bidding process allows the Mobility Authority to get the most competitive pricing on the project and allows multiple businesses to compete for the work.
