The Massachusetts Bay Transportation Authority (MBTA) will begin construction later this fall on a new Orange Line T station in Somerville's Assembly Square.

The Massachusetts Department of Transportation allotted $29,229,184 for the project to S&R Construction Co., Inc. of Lowell Mass., the company in charge of building the new station.

The new stop will be located between the Wellington and Sullivan Square stations and is projected to be in operation for the fall of 2014.

Construction of the new Assembly Square station will impact approximately 200,000 Orange Line riders and an additional one million public transit riders whose travel intersects with the Orange Line each day, according to Wig Zamore, a founding member of Somerville Transportation Equity Partnership (STEP). STEP is a local group that advocates for improved transportation in Somerville.
