Meetings

This page serves as the repository for the meeting minutes which supported the planning and design phases of the Casey Arborway project.  Looking through these documents provides a complete history of how the decision was made to replace the overpass and then how the design for the new roadway evolved from concept to finished product.  As construction on the new Arborway begins, materials developed to support the public involvement process associated with that effort will start to appear on this page.

  • Meeting Minutes
  • Landscape Drawings
    • Corridor
      • Corridor-RENDERED Plan.pdf :

        This figure illustrates how the Corridor Plan connects the Casey Arborway to the existing Emerald Necklace and draws upon Frederick Law Olmsted's 1892 vision for the parkway. Civic scale trees provide linkage to the regional network and enhance cyclist experience. A series of nodes along the corridor weave into the existing context, breakdown the larger scale of the corridor, recognize existing features and create additional points of interest. Roadways are noted in white, pedestrian paths are beige and cycle tracks are blue gray.

      • Corridor-Sections-rendered-FINAL.pdf:

        This figure graphically illustrates proposed cross-sections within the Casey Arborway corridor. The first section shows the proposed relationship of streetscape elements, paths and cycle tracks adjacent the Courthouse. The section describes the proposed elevated pedestrian path along the northeast side of the corridor.

    • Plaza
      • Plaza-A Board.pdf:

        This figure illustrates proposed design “A” in the MBTA and Southwest corridor Plaza areas. Reclaimed granite blocks frame planters that act to define circulation space and allow for flexible plaza use in addition to providing soil volume for trees above the tunnel. A great lawn allows for an informal "beach" that can be activated by events such as farmer's markets, performances, and other informal sports activities. The proposed cycle tracks are noted in blue

      • Plaza-B Board.pdf:

        This figure illustrates proposed design “B” in the MBTA and Southwest corridor Plaza areas. Contained planters, composed of reclaimed granite blocks, provide soil volumes for planted arboretum collections and edges for seating. Spaces between the planters allow for cycle tracks (in blue), pedestrian circulation, and the expanded corners necessary for informal activities like vendors or farmer's markets. The lawn includes both a pedestrian circulation path and remnants of the existing granite wall supporting existing utilities.

      • Plaza-HeadhousePerspective.pdf:

        Artist’s rendering showing the proposed headhouse within the plaza context. Existing Forest Hills Terminal is shown beyond.

    • Shea
      • Shea_Boards-option A.pdf:

        This figure illustrates proposed landscape design “A” in Shea Square. A "reminiscence" of Shea Circle is overlaid on the four corners of the new intersection. The circular pavement is outlined by a double row of tall shade trees of a species unique to Shea Square. A sense of place and of "entry" to the Arborway is created by the opening up of the narrower corridor and the presence of the strong circle of distinctive large trees.

      • Shea_Boards-option B.pdf:

        This figure illustrates proposed landscape design “B” in Shea Square. Each side and corner of the new intersection is designed to respond to what is adjacent. The two northern corners flank the southern entrance to Franklin Park and are addressed with a simple lawn ground plane, pavement minimized to the necessary pedestrian and bike circulation, and informal shade and flowering tree plantings of species related to this naturalized edge of the Park. The south side of the intersection responds to the residential edge with a plaza offering seating for visitors and residents of the Assisted Living Facility, and a more colorful planting at the ground plane.

      • Shea_Boards-option C.pdf:

        This figure illustrates proposed landscape design “C” in Shea Square. This plan is a "hybrid" of Schemes A and B. It overlays the unifying ring of "Shea Square" shade trees over the contrasting ground plane/understory treatments of the north and south sides of the roadway.

  • Headhouse Design
    • A1-Headhouse_Platform_Level_Floor_Plan-2013-05-16.pdf:

      Floor plan of the Forest Hill’s Orange Line platform level depicting the removal of the existing egress only stair and adjacent ventilation exhaust stack (shown in dashed lines), and the proposed platform extension (cross-hatched area) relocating the existing stair approximately 100 feet to the north with new elevator access.

    • A2-Headhouse_Street_Level_Floor_Plan-2013-05-16.pdf:

      Floor plan of the proposed Forest Hill’s Orange Line Head House relocated approximately 75 feet to the north of the current egress only head house. Proposed Head House to provide both fare control access to and egress from the platform below by way of stairs or elevator.

    • A3-Headhouse_Prespective_Views-2013-05-16.pdf:

      This graphic provides four perspective views.

      1. Head House perspective view from the northwest corner looking southeast.
      2. Head House perspective view from the northeast corner looking southwest.
      3. Head House perspective view from the southeast corner looking northwest.

  • Agenda
  • Minutes
  • Meeting Materials:
    • Construction Staging
      • Pre-Stage A

        This drawing displays the first of seven stages. It is called a “pre-stage” because no traffic movements have changed and most construction is off of the roadways. There are off-peak (approximately four hours long) closures of Casey Overpass westbound while temporary walls are installed. Other major work includes the construction of the Upper Busway extension and the Arborway temporary roadway.

      • Pre-Stage B

        This drawing displays the second of seven stages. It is called a “pre-stage” because traffic disruption is minimal and most construction is off of the roadways. This stage includes the demolition of a portion of the westbound, westerly approach of the Casey Overpass and the demolition of the existing Upper Busway. The only restricted traffic movement is Forest Hills Street closure at Shea Circle with access through Cemetery Road.

      • Stage 1

        This drawing displays third of seven stages. At this point, Casey Overpass westbound is closed, with traffic traveling on a temporary at-grade roadway. The westbound easterly and westerly approach abutments and the first spans are demolished. The eastbound temporary Arborway is constructed. In addition, Washington Street Southbound and half of the Upper Busway is constructed.

      • Stage 2

        This drawing displays the fourth of seven stages. At this point Casey Overpass is closed in both directions with traffic traveling on a temporary at-grade roadway to the north. Demolition of the bridge from both approaches to Washington Street to the west and Hyde Park Avenue to the east occurs. Traffic is shifted onto the new portion of Washington street and the Upper Busway and construction of northbound Washington Street and the second half of the Upper Busway occurs.

      • Stage 3

        This drawing displays the fifth of seven stages. Final demolition of the overpass along New Washington Street occurs and Casey Arborway is constructed. Construction of the Frontage Road, Shea Square, and side streets occurs. Construction of new ventilation grates for Amtrak and a new headhouse for the MBTA Orange Line occurs. The MBTA No. 39 bus is relocated to the Upper Busway.

      • Stage 4

        This drawing displays the six of seven stages. Casey Arborway has opened in its final condition from South Street to Forest Hills Street. Construction occurs on side streets, with closures on South Street entering at Washington Street, Arborway Road at South Street, and at Forest Hills Street.

      • Stage 5

        This drawing displays the seventh of seven stages. At this point, most major construction work is complete. The removal of temporary pavement and the final construction of sidewalks, bike paths, and medians is occurring. Final paving, striping, and landscaping is also occurring. Short temporary lane closures and turning-movement restrictions at certain intersections may occur, but are not likely to last more than a week.

  • Route 39 Busway Relocation Alternatives Memo
  • Figure 2A: Route 39 Bus and Taxi Swap

    Figure 2A depicts a proposal to ‘swap’ the area currently used at the MBTA Forest Hills Station for taxis with the area currently used for loading and unloading the Route 39 bus. The proposal shows an additional platform area to be constructed as part of the relocated Upper Busway to house the Route 39 buses. Under this proposal, the area in front of the station would include space for taxis and potentially other uses.

  • Figure 2B: Upper Busway Headlight Impacts

    Figure 2B depicts how the bus headlights would shine towards the residential area across Washington Street as buses exited the relocated Upper Busway. In this concept, MassDOT would collaborate with abutting residents to determine an appropriate method of screening the headlights.

  • Figure 2B-1: Upper Busway Existing Views

    This plan shows two views of the residential neighborhood across Washington Street from the Forest Hills Station Upper Busway. The top image is a view looking towards the neighborhood from the Upper Busway and the bottom picture is a view looking towards the Upper Busway from the neighborhood. The area highlighted in yellow is the existing chain link fence.

  • Figure 2B-2: Screening Examples

    This figure shows examples of light-filtration screening applications in various settings. None of the samples shown are actual designs for the Casey Arborway project, but they depict a range of opportunities available to mitigate for any headlight impacts from a relocated Upper Busway.

  • Figure 3A: Double-Lane Left Turn

    This drawing displays the most recent proposal for the Shea Square intersection design. The design now includes an additional left-turn lane from the Arborway to Circuit Drive.

  • Existing Conditions for the Casey Area

    This drawing displays the existing conditions for the entire Casey Arborway project and the areas immediately adjacent. The colored areas show the different constraints and limitations of the existing roadways, structures, and surrounding developments as they relate to maintaining traffic during construction.

  • Construction Sequence for Demolition - Proposed

    This drawing displays the general method for overcoming the existing constraints in order to demolish the Casey Overpass. The idea is to remove the bridge from the approaches to the center since many of the constraints are at the ends of the bridge.

  • Construction Sequence – Pre-Stage A

    This drawing displays the first of seven stages. It is called a “pre-stage” because no traffic movements have changed and most construction is off of the roadways. There are off-peak (approximately four hours long) closures of Casey Overpass westbound while temporary walls are installed. Other major work includes the construction of temporary pavement for the Arborway temporary roadway and the temporary Upper Busway.

  • Construction Sequence – Pre-Stage B

    This drawing displays the second of seven stages. It is called a “pre-stage” because no traffic movements have changed and most construction is off of the roadways. This stage includes the demolition of a portion of the westbound, westerly approach of the Casey Overpass and the demolition of the existing Upper Busway.

  • Construction Sequence – Stage 1

    This drawing displays third of seven stages. At this point, Casey Overpass westbound is closed, with traffic traveling on a temporary at-grade roadway. The westbound easterly and westerly approach abutments and the first spans are demolished. The eastbound temporary Arborway is constructed. In addition, Washington Street Southbound and half of the Upper Busway is constructed.

  • Construction Sequence – Stage 2

    This drawing displays the fourth of seven stages. At this point Casey Overpass is closed in both directions with traffic traveling on a temporary at-grade roadway to the north. Demolition of the bridge from both approaches to Washington Street to the west and Hyde Park Avenue to the east occurs. Traffic is shifted onto the new portion of Washington street and the Upper Busway and construction of northbound Washington Street and the second half of the Upper Busway occurs.

  • Construction Sequence – Stage 3

    This drawing displays the fifth of seven stages. Final demolition of the overpass along New Washington Street occurs and Casey Arborway is constructed. Construction of the Frontage Road, Shea Square, and side streets occurs. Construction of new ventilation grates for Amtrak and a new headhouse for the MBTA Orange Line occurs. The MBTA No. 39 bus is temporarily relocated to the Upper Busway.

  • Construction Sequence – Stage 4

    This drawing displays the six of seven stages. Casey Arborway has opened in its final condition from South Street to Forest Hills Street. Construction occurs on side streets, with closures on South Street entering at Washington Street, Arborway Road at South Street, and at Forest Hills Street. The MBTA No. 39 bus has moved to its permanent location on the Casey Arborway in front of Forest Hills Station.

  • Construction Sequence – Stage 5

    This drawing displays the seventh of seven stages. At this point, most major construction work is complete. The removal of temporary pavement and the final construction of sidewalks, bike paths, and medians is occurring. Final paving, striping, and landscaping is also occurring. Short temporary lane closures and turning-movement restrictions at certain intersections may occur, but are not likely to last more than a week.

  • Preliminary Design Base Map: The Preliminary Design Base Map displays the proposed roadway network, including edges of pavement, striping, sidewalks, and bicycle paths (as of June 15, 2012, as prepared for the 25% design process). Major changes to the design since the last Design Advisory Group meeting (May 16, 2012) are noted on the Map. This plan represents a “full-build” design to accommodate 2035 traffic projections, with a section of the Casey Arborway carrying three through traffic lanes in each direction between South Street/Washington Street and Hyde Park Ave/Washington Street.
  • Right-Turn Lane Alternative Base Map: The Right-Turn Lane Alternative Base Map displays a “opening year” design of the proposed roadway network, including edges of pavement, striping, sidewalks, and bike paths (as of June 15, 2012, as prepared for the 25% design process). This alternative differs from the Preliminary Design Base Map in that it displays only two through traffic lanes in each direction on the Casey Arborway, with dedicated right-turn lanes.
  • South Street/Washington Intersection: The South Street/Washington Intersection Focus Plan displays a close-up view of the lane arrangements at the South Street/Washington intersection and approaching roadways. The shaded areas depict the difference in roadway width between the Preliminary Design and the Right-Turn Lane Alternative.
