The Neponset River Bridge was constructed in 1970, and serves as a major artery between Quincy and Boston over the Neponset River. The bridge is a 24-span structure with three additional ramps. The average daily traffic consists of 70,700 vehicles.

MassDOT awarded a construction contract for the full rehabilitation of the Neponset River Bridge Phase II to J. F. White of Framingham on January 6, 2010. This project is being constructed as part of the part of the $3 billion Patrick - Murray Accelerated Bridge Program, which aims to restore and repair structurally deficient bridges across the Commonwealth of Massachusetts. The project is 70% complete and the contract end date is scheduled for August 2013.

Purpose and Goals

The goals of the Neponset River Bridge Phase II Rehabilitation Project are to improve the bridge's structural integrity and enhance accessibility. Currently, the bridge deck and joints are in poor condition. During Phase II of the project, the concrete deck, expansion joints, sidewalks and lighting system will be replaced. The project will improve safety and accessibility for pedestrians, bicyclists and automobile traffic and to meet the American's with Disabilities Act. New ADA compliant 8' sidewalks will replace the 4.4' sidewalks and a new access ramp and sidewalk with replace the stairs on the Quincy side of the bridge.

Current Work Schedule

Lane Restrictions/Ramp closures are as follows:

• There will be 3 northbound travel lanes from the mid point of the bridge to Neponset Circle and one southbound travel lane from Neponset Circle to the midpoint of the bridge Monday to Friday from 6 AM to 10 AM.
• At all other times, two lanes will be provided in each direction on the main span of the bridge and southbound traffic traveling to Quincy Shore Drive will be directed to the left lane that will occupy a portion of the northbound side of the bridge and Southbound traffic traveling to Hancock Street will be directed to the far right lane on the southbound side of the bridge.
• The ramp from Quincy Shore Drive to Hancock Street (area of Neponset River Landing beneath the Neponset River Bridge) will reopen November 16, 2011.

Pedestrian Access Impacts:
The northbound and southbound sidewalk are open for pedestrian use.

Hancock Street Bridge over Sagamore Street, the MBTA Red Lines and the MBTA Commuter Rail in the City of Quincy.

MassDOT crews will be implementing a phase change on the Hancock Street Bridge, which carries Sagamore Street over the MBTA Red Line and the MBTA Commuter Rail, in the City of Quincy.

Effective Monday, March 5, 2012 at 3 PM through June 2012, the northbound lanes on Route 3A Hancock Street in Quincy will be closed as part of the phase II bridge demolition. During the work, the bridge will be reduced to one travel lane in each direction on the southbound side and the ramp to Sagamore Street will remain open.

Traffic exiting from the parking lot at Panera Bread and Applebees to Hancock Street northbound (heading towards Boston) will travel to Sagamore Street and proceed approximately one half mile onto Commander Shea Blvd. and turn right onto Quincy Shore Drive northbound. Traffic exiting the parking lot heading to Hancock Street southbound will proceed to Kendall Street and turn right onto Newport Avenue in order to access East Squantum Street back to Hancock Street by North Quincy High School
