Construction of the 45 Southwest Expressway began on November 8, 2016. The 3.6-mile $109 million project is being built by McCarthy Building Companies, Inc. Construction is expected to take approximately three years with opening of the new expressway slated for late 2019.
The Mobility Authority oversaw design of the project and has contracted with McCarthy Building Companies to construct the project. Once the project is complete the Mobility Authority will operate and maintain the 45 Southwest Expressway.
TxDOT was the lead agency in the development of the SH 45SW environmental study, including related environmental documentation and coordination of public outreach.
