comm-ave-bridge-work-august-10-2017MassDOT has announced that work continues 24/7 on the Commonwealth Avenue Bridge eastbound deck and MBTA Green Line B Line tracks and it is anticipated that, weather permitting, trolleys and private motor vehicles will be able to use the area of the bridge by the middle of the upcoming week.

In the last 24 hours, some of the final construction-related activities such as placing rail and grout have been taking longer than planned, and weather conditions including rain have delayed some of the pouring of concrete.

At this time, crews continue placing rail and concrete on areas of the deck. The concrete will need to cure for at least 24 hours and the rail must be tested prior to service. Other current activities include building sidewalks, curbing, putting in place waterproofing materials, installing final pavement and markings, and carrying out other finishing work. Weather permitting, trolley service on the MBTA Green Line B-Branch and private vehicle access to the Commonwealth Avenue Bridge and Boston University Bridge and local roadways will resume by the middle of the upcoming week.

“While some of our construction activities on Friday and Saturday have required more time than expected, our crews continue to focus on operations related to the project around the clock,” said Transportation Secretary and CEO Stephanie Pollack. “This weekend’s scheduled work, by necessity, is continuing into the upcoming week while our crews continue to finish building the eastbound side of the deck of the Commonwealth Avenue Bridge. We appreciate the cooperation and understanding of the local community, residents and commuters, area businesses, and civic leaders, and thank them for their patience and efforts to consider travel options during this construction project.”

“Crews have been working diligently with tasks such as setting rail and grout and project managers for MassDOT and the MBTA decided collaboratively to adjust the project schedule so the impacts to the MBTA Green Line service and restrictions to private vehicular travel along local roadways and Commonwealth Avenue will continue into the beginning of the upcoming week,” said Acting Highway Administrator Jonathan Gulliver. “Work crews will be letting the concrete that is being poured later this weekend and early next week cure, and will also be taking advantage of this schedule to conduct work on the MBTA Green Line B rail, sidewalks, curbing, and carrying out other finishing work that is scheduled to continue into the following weeks. This has been a full team effort and decision by MassDOT engineers, MBTA personnel, as well as the contractor and project team, and we are working to complete our operations as efficiently as possible.”

The full upcoming schedule is as follows:

  • Through the middle of the upcoming week: the BU Bridge and Commonwealth Avenue Bridge are anticipated to remain closed to private vehicles.
  • Through the middle of the upcoming week: the MBTA Green Line B will continue to accommodate customers with bus shuttles for stops in the area of the Commonwealth  Avenue Bridge.
  • Through the middle of the upcoming week: MBTA bus route detours continue.
  • I-90: four lanes of travel east and westbound under the Commonwealth Avenue Bridge will be maintained.

In several days, bridge deck construction operations will transition from the intensive structure replacement work to finishing tasks such as completing the final paving work as well as installing curbing and sidewalk. These minor operations are expected to occur throughout the coming weeks and are not expected to significantly impact traffic or the local community. Accommodations including temporary pavement markings, delineated bicycle lanes, and detours for pedestrians around the minor finishing work will be in place in this area.

For the next several weeks, there will be short term, off-peak lane reductions on Commonwealth Avenue in the vicinity of the bridge to allow for the finishing work and minor operations. Crews will also carry out utility relocations and signal work between the major operations this summer.  Next summer, the westbound deck of the Commonwealth Avenue Bridge will be replaced. Members of the public are encouraged to check transit schedule information to learn about B Line bus shuttles and regular service:  www.mbta.com.  In addition, MassDOT’s free app, GoTime, (www.MassDOTgotime.com), has real-time travel time to specific destinations on major roads in the state.  Other resources to learn of real-time information include the following Twitter accounts:  @MassDOT @MBTA and @MBTA_CR.

The Commonwealth Avenue Bridge Project has been years in the planning and logistics are being deployed in such a way as to best to shorten the length of time the work will impact the public.  MassDOT contractors will continue to work continuous shifts seven days a week and utilize Accelerated Bridge Construction techniques in order to reduce the overall construction duration and minimize the impact on travelers.

This project, which would take an estimated four to five years using conventional techniques with significant lane-takings and service disruptions, is scheduled for two short duration construction phases.  The eastbound side of the bridge deck of the Commonwealth Avenue Bridge and the MBTA Green Line B track area are being replaced now and in the summer of 2018, the westbound side of the bridge deck will be replaced.  In addition to a new bridge deck, the entire project will result in functional and safety improvements for vehicles, the B Line, for cyclists and for pedestrians.

The full project impacts of the Commonwealth Bridge Project are as follows:

For Pedestrians and Bicyclists:

  • Pedestrians and bicyclists are able to travel across a portion of the Commonwealth Avenue Bridge on the westbound side throughout construction this summer.
  • Bicyclists heading in some directions will encounter occasional minor detour routes, such as, where they are able to cross Commonwealth Avenue.
  • Some areas of Commonwealth Avenue near the construction zone have jersey barriers and fencing to protect the public from heavy construction equipment which is deployed and sometimes moving along the road.  As always, during the construction period, pedestrians and bicyclists will have full access across the Commonwealth Avenue Bridge on the westbound side.
  • Due to safety and logistic reasons, the temporary mid-block crossing between Carlton Street and St. Mary’s Street has been closed.  The western crosswalk at the Commonwealth Avenue/St. Mary’s intersection has been re-opened, allowing pedestrians and cyclists to cross Commonwealth Avenue at St. Mary’s Street under police detail control.
  • Eastbound bicyclists heading to the BU Bridge will cross Commonwealth Avenue at St. Paul Street to a shared bike/bus travel lane in the westbound roadway.  Bicyclists continuing eastbound will cross back to eastbound Commonwealth Avenue at St. Mary’s Street.
  • Westbound bicyclists will continue to use the existing westbound bicycle lanes.  There are no crossings between Amory Street and St. Mary’s Street.
  • As before, there will be portions of the route near the work zone where cyclists will have to walk their bicycles.
  • There are additional Hubway bike rental stations on Commonwealth Avenue during the shutdown (see below).

For Drivers:

  • Commonwealth Avenue Users:

o   Commonwealth Avenue (between Packard’s Corner and Kenmore Square) is closed to non-emergency and non-MBTA bus shuttle traffic (local access only) until the middle of the upcoming week.

o   See the “Commonwealth Avenue Closure Detour” on the Traffic Management page.

o   Access is maintained for businesses and abutting properties. 

  • Boston University (BU) Bridge Users:

o   The BU Bridge is closed to non-emergency vehicular traffic until the middle of the upcoming week. See the “Boston University (BU) Bridge Closure Detour” on the Traffic Management page.

  • I-90 (Mass Pike) Users:

o   Four lanes of travel in each direction under the Commonwealth Avenue Bridge now and on very rare occasions perhaps in the coming weeks there may need to be periodic, off-peak lane reductions on I-90 for short-term durations as needed.

For MBTA Green B Line Users:

  • The Green B Line in the area of the Commonwealth Avenue Bridge has been replaced with shuttle buses between Babcock Street and Blandford Street Stations until the middle of the upcoming week. These buses have regular stops along the detour route for boarding/disembarking.
  • For more information, please visit the Green Line page on the project website.

For MBTA Bus Users:

  • MBTA Bus Routes CT2 and 47 are detoured from the normal routes until the middle of the upcoming week.
  • See the MBTA Bus page on the project website.
  • Route 57 Bus is operating its normal route.

MassDOT Encourages Active Transportation

  • There are recently installed pedestrian and bicycle wayfinding signage near Green Line shuttle bus stops on Commonwealth Avenue and in the area of Boston University to non-motorized travel especially for short trips. The signs list walking and biking distances to specific destinations.  This is helping to optimize shuttle bus operations by shortening bus wait times and headways.  In general, the public will find it a ten minute walk from where the B Line trolley service will terminate due to construction and from where the B Line train service will resume. 

Additional Hubway Stations

  • MassDOT is partnering with Hubway to provide additional temporary Hubway stations on Commonwealth Avenue during the construction period so the public can rent a bike.   These stations are located at:

o   Babcock Street

o   Silber Way

  • Hubway Ambassadors are assisting users at these temporary locations Monday through Friday from 7:00 a.m. through 10:00 a.m. and from 4:00 p.m., though 7:00 p.m., providing additional bikes on a first-come, first-serve basis. All existing Hubway stations along Commonwealth Avenue and the rest of the Hubway service area will continue to be operational. 

For New Hubway Users

  • Download the brand new Hubway mobile app, available for iPhone and Android.
  • Use the app to find a station near you.
  • You can also get a pass via the app (only $1 for a single trip or save $20 on a full annual membership during the shutdown.)
  • For more information, visit thehubway.com, and download the new Hubway mobile app.
