The Central Corridor light-rail line received a $106.7 million funding boost Wednesday.

The Counties Transit Improvement Board, a regional group that helps advance and invest in transit, awarded the project its third of four grants. The board promised to pay 30 percent of the capital costs for the light-rail line.

The money will cover final design, right-of-way acquisition, vehicle design and construction.

The Central Corridor light-rail will connect downtown Minneapolis and St. Paul on an 11-mile line that is estimated to cost $957 million.

The CTIB receives funding from a quarter of a percent of county sales tax and vehicle registration fees from five of the seven counties making up the Twin Cities metro, including Hennepin, Ramsey, Anoka, Dakota and Washington counties.

The board also awarded grants to other projects. The Southwest Corridor, which will connect downtown Minneapolis with southwest suburbs, received $12.2 million and the Cedar Avenue Bus Rapid Transit project received $12.9 million.
