A plan to redevelop downtown Quincy is getting an $8.1 million boost in federal stimulus money.

Gov. Deval Patrick and Congressman Bill Delahunt announced Monday a grant that will help the second phase of a project meant to make improvements on Revere Road, an east-west connector road that will tie together the Quincy downtown area.

The project includes the reconstruction and realignment of 1,900 feet of roadway and the demolition of a city-owned building. The roadway will eventually connect a bridge to provide motorist and pedestrian access over the rail corridor.

The Quincy downtown area has long been separated by a north-south rail corridor.

Patrick said in a statement the project will "unlock economic development opportunities."
