Congress will need to enact an appropriations bill to dole out the new dollars included in an already-approved $1.2 trillion infrastructure package, but once that happens, Massachusetts is set to receive a first-year increase of more than $215 million to the funding it receives for highways and transit, a state Department of Transportation official said Wednesday.

Officials continue to unpack the impacts of the new law, which reauthorizes federal funding programs under the Obama-era FAST Act with more money to improve the nation’s roads, bridges, railroads and buses, and to help prepare for the impacts of climate change.

MassDOT Director of Capital Planning Michelle Ho said Wednesday that early projections indicate that the Bay State will see a roughly 19 percent increase in formula funding for highways in federal fiscal year 2022, from $678.7 million in the current spending cycle to $804.6 million.

“That’s a significant increase for us overall,” Ho said.

On the transit side, Ho said the MBTA, MassDOT and the state’s regional transit authorities should receive about $483 million in federal fiscal 2022, a $92.5 million or 23.6 percent increase over fiscal 2021.

Ho added that it may be “challenging” for the Bay State to program all of the new funding in the 2022 federal spending year, which runs through September 2022, once the money begins to flow. Massachusetts can compete with other states for sizable pots of additional grant funding, which Ho said MassDOT and the T would “aggressively pursue.”

The state Transportation Department will also return to a five-year model for crafting capital spending programs and work on a plan covering 2023 to 2027, a shift back toward the norm after using single-year plans amid the uncertainty of the pandemic.
