Funds to replace the aging Bourne and Sagamore bridges did not make the cut Wednesday when the Federal Highway Administration announced $2.1 billion in bridge grants as part of a first round of funding under the Bipartisan Infrastructure Law.

The omission was announced in a press release from the Massachusetts Department of Transportation, which expressed disappointment by the outgoing administration of Gov. Charlie Baker.

“Despite these bridges being federal assets, the administration has spent considerable time, energy and funds to support replacing the bridges, including working with the Legislature to pass significant funding to replace the approaches to the bridges and authorization for Massachusetts to compete for federal grants,” MassDOT spokesperson Jacquelyn Goddard said in the release.

The U.S. Army Corps of Engineers had applied for $1.882 billion from the Federal Highway Administration to replace the two bridges that connect the Cape to the mainland over the Cape Cod Canal. A 2019 study found the bridges to be functionally obsolete. The funding request represents 47 per cent of the estimated $3.976 billion total project cost.

Although the Army Corps currently owns and operates the two bridges, once the bridges are rebuilt responsibility for their maintenance will shift to the MassDOT under a determination made in 2020.

The grants announced Wednesday will fund construction of four projects: the Brent Spence Bridge connecting Kentucky and Ohio over the Ohio River, the Golden Gate Bridge in California, the Gold Star Memorial Bridge on I-95 between New London and Groton, Conn., and four bridges spanning the Calumet River on the southside of Chicago.

The infrastructure law includes funding of nearly $40 billion over five years for bridge reconstruction.

In a joint statement, U.S. Senators Elizabeth Warren and Edward Markey and U.S. Rep. Bill Keating, said it was "frustrating" that the bridges were not included in the current funding round. But they noted that the Biden adminstration had previously awarded a $1.6 million planning grant for the project, which they said signaled a "strong commitment" to reconstruction of the bridges.

“Congress has appropriated unprecedented infrastructure money for bridges around the country, and we remain confident that the Army Corps and MassDOT can learn lessons from this grant cycle to submit a more competitive application in the next round of federal funding," the statement continued. "Cape residents deserve safe, secure public infrastructure and we’ll continue to work with federal, state, and local partners until it’s delivered.”
