From our friends at MGNA…
The MBTA today began to solicit bids for Phase I of the Green Line Extension project with an advertisement in the Boston Globe.
Phase I, scheduled to being late this year or early next year, will consist of three elements:
+ In South Medford, reconstructing and widening the railroad bridge over Harvard Street to accommodate the Medford Branch extension. Work includes relocating the commuter rail tracks, building retaining walls/noise barriers, and performing ancillary utility and roadway improvements
+ In Somerville, widening of the railroad bridge over Medford Street, which currently carries the Fitchburg commuter rail tracks. This bridge will carry the Union Square branch Green Line tracks.
+ In Cambridge, demolition of the MBTA tire facility building at 21 Water Street. This property will be used for staging and parking during later phases of construction.
Estimated cost of the Phase I work is $18.3 million – $15.3 million for the two bridges, and $3 million for the building demolition.
Bidding documents will be available at the Contract Administration Office (Room 6720, State Transportation Building, 10 Park Plaza, Boston) on Wednesday, July 18, from 8:30 a.m. to 4 p.m.
