MassDOT crews will be installing barriers and setting the work zone for the first phase of construction on the Neponset River Bridge Phase II, which carries traffic between Boston and Quincy. During the work, the following lane restrictions will be in place for the week of April 11th. The MassDOT Neponset River Bridge construction web page is here.
On Sunday, April 11, through Thursday, April 15, the northbound (inbound) lanes of Quincy Shore Drive will be closed for barrier installation from 9 PM to 5 AM and all northbound traffic will be detoured at the northbound exit ramp near the Adams Inn and through the Quincy Loop in order to reverse direction and access the bridge northbound from Hancock Street.
On Monday, April 12, the left lane in the southbound (outbound) direction will be restricted on the bridge from 7 AM to 3:30 PM and the left lane in the northbound (inbound) direction on the bridge will be restricted from 9:30 AM to 3:30 PM. At the completion of the work on Monday, April 12th, the left lane closure in the northbound direction will remain in place from Quincy Shore Drive up to the area of the mid point of the bridge as part of the permanent traffic management plan for the first phase of construction.
On Tuesday, April 13, through Friday, April 16, the left lane in the southbound (outbound) direction and the left lane in the northbound (inbound) direction in the area from the midpoint of the bridge to Neponset Circle will be restricted on the bridge from 7 AM to 3:30 PM.
On Sunday, April 11, between 9 PM and 5 AM, the traffic signals at Neponset Circle will be modified to facilitate traffic flow during the construction period. As part of this work, the dual right turn lanes from Gallivan Boulevard northbound around and up on to the bridge will be brought under full signal control. These lanes currently are controlled by a flashing yellow light and YIELD signs. Beginning Monday morning, April 12th, drivers turning right at this location MUST adhere to the traffic signal indications (green, yellow and red).
