The Federal Highway Administration (FHWA) awarded $33.43 million under the Highway Planning and Construction program (CFDA 20.205) to the Massachusetts Department of Transportation (MassDOT) on August 28, 2025, for the Wilmington Bridge Replacement project (W-38-029). This formula grant funds the complete replacement of the State Route 129 Lowell Street bridge over Interstate 93 in Wilmington, Massachusetts, with an anticipated completion date of July 1, 2032. The project encompasses design, environmental clearance, and construction activities necessary to replace the existing bridge infrastructure on this state highway corridor.

The Highway Planning and Construction program provides federal-aid highway funding to states on a formula basis for highway and transportation infrastructure improvements, including bridge replacement and rehabilitation, roadway reconstruction, and related safety enhancements. As the designated state transportation authority, MassDOT administers this formula grant directly and is responsible for project execution, oversight, and compliance with applicable federal environmental and design requirements. This award represents one component of MassDOT's broader transportation infrastructure portfolio, which receives the majority of its federal funding through the Federal Highway Administration.
