Neponset River Bridge 3 MassDOT’s Contractor will be installing the final components associated with the work zone for the first phase of construction on the Neponset River Bridge Phase II, which carries traffic between Quincy and Boston. 

On Friday, April 30, through the weekend, the Northbound left lane will be closed from the midpoint of the bridge to Neponset Circle and the Southbound right lane will be closed.  Other closures:

Monday, May 3, from 7 AM to 3:30PM – there will be a Southbound double, left-hand lane closure.

Monday May 3, at 3:30 PM to Tuesday, May 4 at 7 AM – the Southbound right lane will be closed.

Tuesday, May 4, from 7 AM to 3:30 PM there will be a Southbound double, left-hand lane closure.

Tuesday May 4, from 3:30PM to Wednesday, May 5 at 7 AM the Southbound right lane will be closed.

Wednesday May 5, from 7 AM to 10 AM there will be a Southbound double, left-hand lane closure.

On Wednesday, May 5 at 10 AM, the remaining components of the Phase I work zone will be implemented.  Beginning at approximately 3:00 PM, 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 in order to accommodate the work zone.

Once the Phase I work zone is implemented, 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 weekdays between 6 AM to 10 AM.  At all other times, two lanes will be provided in each direction on the main span of the bridge; however, there may be instances where only one southbound travel lane from Neponset Circle to the midpoint of the bridge will be available between 10:00 AM and 3:30 PM weekdays to allow for construction activities to occur. 

MassDOT strongly advises drivers to reduce speed and use extreme caution when travelling through the work zone.  MassDOT encourages auto commuters to consider alternative transportation options.  For information visit www.mbta.com or contact the MBTA Customer Support Services Center at (617) 222-3200 or TTY (617) 222-5146. Customer Service representatives are available Monday-Friday 6:30 AM – 8:00 PM and Saturday-Sunday from 7:30 AM – 6:00 PM.  MassDOT's Neponset River Bridge website is here.
