Fore River Bridge Replacement Project, Quincy | Weymouth

Massachusetts Department of Transportation
Route 3A, Quincy/Weymouth, Massachusetts

The deteriorating Fore River Bridge carries 32,000 vehicles per day and is a gateway to the South Shore. The Massachusetts Department of Transportation (MassDOT) constructed a new, permanent, movable bridge that safely and efficiently met cyclists’, pedestrians’, drivers’, and maritime users’ needs while improving residents’ and drivers’ quality of life through fewer and faster bridge openings. HSH developed all traffic engineering plans, including temporary traffic control plans (TTCPs), interconnected traffic signals, signage, and markings, including re-design of striping of the rotary to the west of the bridge. We evaluated and designed mitigation for alternate routes and performed an extensive evaluation to determine a very specific Limitations of Operations regarding required numbers of lanes by seasonality and time of day. 

HSH performed a comprehensive outreach program across the South Shore to find alternate routes for motorists and to understand what the lane restrictions would mean for their daily commute. HSH provided support to MassDOT’s press and legislative liaison units for site walks by local media and elected officials; briefings to the Mayors and their key staff; and public information meetings in Quincy and Weymouth, among other public outreach tasks.
