October 9. 2014 MBTA Red Line Weekend Diversion – October 11 

On Saturday, October 11, the Massachusetts Department of Transportation (MassDOT) will close the Longfellow Bridge to all motor vehicle travel, except MBTA buses. The closure is necessary to implement an MBTA Red Line diversion to accommodate bridge construction. Buses will replace Red Line trains for service between Kendall/MIT Station and Park Street Station, with a stop at Charles/MGH Station. The bus route and stops are shown on this map. All shuttle bus stops are accessible for people with disabilities.

Bus service will be in place for Boston and Cambridge-bound Red Line customers during service on Saturday, October 11. Red Line trains will resume service on Sunday morning, October 12. The diversion is necessary for MassDOT’s design/build contractor, White-Skanska-Consigli JV, to perform work in close proximity to the Red Line tracks that is not possible during MBTA service hours. Please visit the MBTA’s service updates webpage for additional information.

MBTA buses will be the only motor vehicles permitted on the bridge. All other motor vehicles, including passenger vehicles, trucks and all other buses, will need to use one of two routes to reach Boston. One route uses Memorial Drive westbound to make a U-turn at Ames Street for access to Memorial Drive eastbound to Land Boulevard and Charles River Dam Road (Monsignor O’Brien Highway/Route 28) to reach Leverett Circle. A second route uses 3rd Street and Binney Street to reach Land Boulevard. Truck restrictions are in place for Memorial Drive.

Emergency response, bicycle and pedestrian access will be maintained across the bridge during this weekend diversion. Please note: Bicyclists must walk their bikes on the sidewalk across the Longfellow Bridge to ensure the safety of all bridge users. The Massachusetts Avenue Bridge and Dr. Paul Dudley White Bike Path across the Craigie Dam Bridge can be used as an alternate route to ride bicycles across the Charles River.

The Cambridge-bound detour remains in place using a signed route from Charles Circle following Charles Street to Leverett Circle, Monsignor O’Brien Highway/Charles River Dam Road and Edwin H. Land Boulevard.

MassDOT to Motorists: Plan Ahead for Bowker Overpass Construction Work
Storrow Drive EB Fenway Route 1 South Offramp Closure is Saturday, August 9th

On Saturday, August 9, the Storrow Drive Eastbound, Fenway Route 1 South offramp will be closed from the hours of 7 AM to 11 PM.  The closure is due to construction work scheduled on the Bowker Overpass

A traffic detour will be in place, directing cars to the previous Kenmore exit along Storrow Drive Eastbound.  There will be signage, and police details to guide motorists to exit at the Kenmore off-ramp.  Work will also require a right lane closure along Beacon Street where access to the sidewalk and bike path will be closed, and traffic will be maintained in the center and left lane.

The scheduled work consists of demolition of deck surface along the Bowker Overpass.  Rapid set concrete will then be installed and finished to match existing grade of bridge deck. Upon completion of recommended curing, traffic will be opened.

MassDOT encourages drivers to avoid the area and seek alternate routes to minimize delays.  Those traveling through the area should expect delays and should reduce speed and use caution while traveling along the detour routes.

“Salt and Pepper” Tower Dismantling to Begin this Week

More than 100 years after the last stone was set on the “salt and pepper” towers of the Longfellow Bridge, the Massachusetts Department of Transportation (MassDOT) will begin dismantling them for storage, cleaning, and repair as part of the Longfellow Bridge Rehabilitation Project. The work is anticipated to begin later this week, and is weather dependent.

The tower dismantling work will take place using a barge-mounted crane on the Charles River. On Thursday, March 6, MassDOT’s contractor, White-Skanska-Consigli JV, will begin preparations by moving into place the crane via barge from the staging area in Charlestown to the upstream side of the bridge. An ice-breaker will precede the barge to provide an unobstructed path. Once the crane is in position at the Cambridge tower the granite stones will be removed and loaded on a barge. The stones will be taken to the contractor’s staging area for cleaning, storage, and repair.

The towers will be dismantled to sidewalk level only. All remaining pier granite below the sidewalk will be restored in place. During stone removal, waterway access will be partially restricted through span 7 (see waterway navigation plan attached), immediately adjacent to the tower. Booms and lighting will be deployed in accordance with US Coast Guard requirements for boater safety.

Concurrent with the tower granite removal, the contractor will need to demolish a concrete liner to expose the inner face of the tower stonework. The concrete demolition work will take place from staging set within the towers and will not be visible to pedestrians from street level. Once the Cambridge-side tower is dismantled, the contractor will start work on the adjacent upstream Boston tower (or Pier 5). The two downstream towers will be dismantled and restored when that side of the bridge is rehabilitated during the final phase of construction, which is planned to begin in fall 2015.

As conditions dictate, the uppermost stones comprising the tower roof may need to be removed using a mobile crane situated on the bridge deck. In this case, the work will be done at night, during MBTA Red Line non-service hours.

The contractor plans to rebuild the iconic towers after seismic reinforcement construction is completed within the bridge tower piers. The fully restored upstream “salt and pepper” tower stonework is planned to be reassembled on the bridge later this year.

Cambridge-Bound Vehicle Detour begins on July 20

Beginning on July 20, 2013, the Massachusetts Department of Transportation (MassDOT) will begin major construction activity on the Longfellow Bridge (State Route 3), which connects Boston and Cambridge over the Charles River.  As part of the rehabilitation project, the bridge will be closed for vehicular travel in the Cambridge-bound direction.  This three and a half year project will rehabilitate the iconic “Salt and Pepper” Bridge to improve structural integrity and capacity, meet modern codes (including ADA accessibility), and create a safer configuration for all bridge users.

One vehicle travel lane to Boston, MBTA Red Line service inbound and outbound, emergency response, and bicycle and pedestrian access will be maintained throughout construction.  

Effective July 20, 2013 through September 2014, one lane of traffic will carry vehicles into Boston (using the current Cambridge-bound lane) and Cambridge-bound traffic will be detoured using a signed route from Charles Circle to Land Boulevard using Leverett Circle and Monsignor O’Brien Highway (detour route map is attached).

Subsequent to September 2014, the Boston-bound travel lane will shift its position on the bridge while keeping the Cambridge-bound detour in place. 

Preliminary work to prepare for construction and the traffic shift began in April 2013 and will be completed by July 20. Traffic signal timing changes, lane restriping, and curb modifications at five area intersections will accommodate the traffic management plan. Overhead highway signs on I-93 and I-90 and portable variable message boards on local roads will provide advance notice of traffic pattern changes. Traffic conditions will be monitored at key locations and through the use of traffic cameras installed as part of the project.

Tree Removal begins in Boston and Cambridge on July 8

On July 8, the Massachusetts Department of Transportation’s (MassDOT) design/build contractor for the Longfellow Bridge Rehabilitation Project, White-Skanska-Consigli (WSC), will begin removing trees as part of preliminary work to prepare for major construction. The work will begin with removal of trees on Mugar Way in Boston for construction of the new Americans with Disabilities Act (ADA) compliant pedestrian bridge from Charles Circle to the Esplanade. Trees on the south (upstream) side of the bridge in Cambridge will be removed to begin rehabilitation of the bridge. Trees that will be removed during Phase 1 of the project are marked with a yellow ribbon and paint. Trees that will be removed in a later phase are marked with a yellow ribbon only. This preliminary work also includes transplanting eight trees in Boston and nine in Cambridge, which will be completed in mid-July. Trees that will be transplanted are marked with a green ribbon. Please refer to the Tree Protection and Removal Plan on the project website for details.

 

WHAT’S NEW

WSC will implement Traffic Stage 1 in mid July 2013. The proposed traffic management plan for Stage 1 includes closing the west side of the bridge for construction and shifting Boston-bound traffic to the east side of the bridge. Cambridge-bound traffic will be detoured using a signed route that starts at Charles Circle and uses Charles Street and Storrow Drive to reach Leverett Circle, a left turn onto Monsignor O’Brien Highway and a left onto Land Boulevard to reach the Kendall Square area. View the proposed detour map.

Preliminary work on Main Street in Cambridge includes removing trees just north of the MBTA’s Kendall portal and modifications to the median to install jersey barriers to accommodate the traffic shift. Please view the public notice of the preliminary work and map of the Main Street median crossover.

Ongoing preliminary work in Boston, includes new signals, curbing modifications and lane restriping at Charles Circle to accommodate the new traffic pattern of inbound traffic entering the circle on the east side. Additional modifications are being made at Mugar Way and the Storrow Drive westbound off-ramp to accommodate construction of the new pedestrian bridge.

July 10, 2013 Public Meeting
