MBTA and MassDOT staff today presented plans for a $2.3-billion Green Line Extension that would keep the originally planned seven stations but would eliminate amenities such as fully enclosed waiting rooms, escalators, fare gates and, at several stations, elevators and stairs.
The proposal would also cut in half the size of a maintenance facility - and shorten the length of a proposed community path alongside the tracks. Several bridges that had been originally slated for complete replacement will instead stay as is, due to changes in track alignments.
A key part of the savings would be roughly $204 million in the fees paid to contractors and consultants to oversee the work.
Last week, Somerville and Cambridge officials vowed to seek local approval to pour $75 million into the extension to keep it afloat - including money already committed by the developer of the North Point project towards relocating and improving the Lechmere station.
Even with the savings, the project is still roughly $300 million above what was once supposed to be a $1.92 billion cost - $1 billion of which would come from the federal government. Staffers suggested looking for fill the gap with contributions from local businesses that would benefit from the new trolley line and from the city of Medford.
