Upcoming Work

3-Week Look-Ahead: September 26th to October 14th

Work will not take place on Monday, October 10th, in recognition of Columbus Day.

Throughout the period covered by this look-ahead, work will take place below ground at Forest Hills Station.  During all three weeks, electric components associated with the jet fans and the jet fans themselves will be installed.  To facilitate this work, one side of the Forest Hills platform is shut down.  This condition will continue through December, 2016.  The MBTA has a protocol in place to ensure that this temporary condition, which the agency has used elsewhere in its system, does not impact service.  Taking this approach allows work to proceed without resort to weekend or late night bus substitutions.

During the week of September 26th, operations will concentrate on the following:

  • For the area between Washington Street and Shea Circle:
    • Installation of light poles
    • Installation and wiring of traffic signals for the future Shea Square
    • Installation and wiring of traffic signals at Cemetery Road
    • Installation and wiring of traffic signals at the eastern median U-turn
    • Placement of sidewalk between Shea Circle and the courthouse
    • Construction of the frontage road between Washington Street and the courthouse
    • Placement of trees between Washington Street and Shea Circle
  • For the area west (towards the Arboretum) of South Street formerly occupied by the overpass:
    • Full depth reconstruction of the eastbound (towards Franklin Park) Arborway from the western limits of work to the crest of the hill.  This operation requires the short segment single lane eastbound Arborway implemented during the week of September 15th.  This operation remains on track to be completed by September 30th. 
  • At Forest Hills Station forming and reinforcing of the upper busway deck will continue.
  • At the intersection of Washington Street/New Washington Street, a northbound (towards Doyle’s Café) left turn arrow signal will be implemented.

During the week of October 3rd, operations will concentrate on the following:

  • For the area between Washington Street and Shea Circle:
    • Installation of light poles
    • Installation and wiring of traffic signals for the future Shea Square
    • Installation and wiring of traffic signals at Cemetery Road
    • Installation and wiring of traffic signals at the eastern median U-turn
    • Construction of the frontage road between Washington Street and the courthouse
  • For the area west (towards the Arboretum) of South Street formerly occupied by the overpass:
    • Setting up of westbound (towards the Arboretum) traffic for water line work.  In this set-up, two lanes heading up the hill will remain available for westbound traffic; however, these lanes will split apart for a short segment to allow a safe work zone for water line construction.
  • At Forest Hills Station, concrete for the upper busway deck will be poured.

During the week of October 10th, operations will concentrate on the following:

  • For the area between Washington Street and Shea Circle:
    • Installation of light poles
    • Installation and wiring of traffic signals for the future Shea Square
    • Installation and wiring of traffic signals at Cemetery Road
    • Installation and wiring of traffic signals at the eastern median U-turn
    • Construction of the frontage road between Washington Street and the courthouse
  • For the area west (towards the Arboretum) of South Street formerly occupied by the overpass:
    • Installation of new 48-inch water lines
  • At Forest Hills Station, forming and reinforcing of the upper busway sidewalk and median will begin

All work is subject to weather conditions.

For your safety:

Motorists: are reminded to reduce speed, pay close attention to all signals, pavement markings, signage and directions from police details. In particular:

  • Yield to pedestrians on turns. This is particularly important at the intersection of New Washington Street/South Street where some motorists have been observed disregarding clearly visible signage.
  • Please do not block the box at intersections. If you cannot clear the intersection on its opposite side, do not proceed until there is space for you to do so.
  • Please do not turn onto Martinwood Road from South Street as a way to access Washington Street. Making this movement requires you to pass through two Do Not Enter signs. Doing so is both illegal and dangerous.
  • Please do not take a left turn at the bottom of the eastbound off-ramp to South Street. This ramp is now right turn only from both lanes. This condition has been and will be enforced by State Police.
  • Motorists with destinations on Hyde Park Avenue, Washington Street north of Forest Hills or east of Franklin Park are reminded to bear left on the Arborway east of Murray Circle to access the eastbound temporary roadway. Please do not exit to the right at the end of the Arborway unless you are bound for Forest Hills Station, Roslindale Square or points south on Washington Street. Making a loop around Forest Hills Station to go east to Shea Circle takes longer and is counterproductive to the successful operation of the temporary traffic set-up.
  • Likewise, motorists seeking to access Shea Circle and points east should remain on the mainline Arborway. Using the Arborway Carriage Road to go east to Shea Circle ultimately takes longer and is counterproductive to the successful operation of the temporary traffic set-up.

Pedestrians: are reminded to please cross only at designated crosswalks. Any crosswalk which has been temporarily removed has been taken out for your safety. This applies particularly to the former crosswalk at the South Street end of New Washington Street and the former crosswalk on South Street at the Route 39 bus driveway. Pedestrian routing diagrams have been made available to WalkBoston, Livable Streets, were shared at the May public information meeting, and are posted in Forest Hills Station. To receive a routing diagram, please contact CaseyArborway.Construction@dot.state.ma.us.

Cyclists: are reminded that when passing over the connections between the Southwest Corridor Path and Washington Street or South Street, cyclists should reduce speed and watch for pedestrians as these are shared pathways. Cyclists may occupy the full lane within the work zone, but must obey all signage and signals.
