Widen road-add lanes on SL 1604 from IH 10 to US 281.

The Federal Highway Administration (FHWA) awarded $43.4 million to the Texas Department of Transportation (TxDOT) on August 14, 2025, under the Highway Planning and Construction program (CFDA 20.205) to widen State Loop 1604 and add lanes on the corridor between Interstate 10 and U.S. Route 281 in Texas. This formula grant supports highway construction and improvement activities authorized under the Infrastructure Investment and Jobs Act, enabling TxDOT to enhance transportation capacity and safety on this critical state highway corridor.

The award funds the design and construction phases of the road widening project, which represents a typical highway infrastructure improvement eligible under CFDA 20.205. As a formula grant administered through TxDOT's established transportation planning processes, the funding supports the state's prioritized highway construction activities in compliance with Federal Highway Administration approval requirements, environmental review standards, and applicable federal regulations. The substantial funding level reflects the scope and complexity associated with multi-lane highway expansion on a major regional transportation corridor.
