Casey Overpass MapA public hearing to discuss the 25% design for the Casey Arborway Project is scheduled for:

Wednesday, February 27th, 5:30pm- Open House, 6pm- Design Hearing

Boston English High School Auditorium, 144 McBride Street

The Monsignor William J. Casey Overpass is the elevated section of Route 203 connecting the Arboretum at the Arborway over Washington and South Streets in Jamaica Plain.

The Overpass area serves many neighborhoods and constituencies, including walkers, bicyclists, MBTA riders, and motorists.  The area is also an important connection to such Boston institutions as Franklin Park, Forest Hills Cemetery, Shattuck Hospital, and the Arnold Arboretum, among others.

The overpass is structurally deficient and suffers from numerous superstructure and substructure problems due to a combination of deterioration and flaws in the original design.  The structure has deteriorated to a point where it can no longer be maintained.  Funding from the Patrick-Murray Administration's Accelerated Bridge Program is available to replace the existing Casey Overpass and examine opportunities for an improved transportation network in the area.

In March 2011, MassDOT initiated a study of alternatives to replace the existing Casey Overpass, to identify safe, accessible, multi-modal landscape, streetscape, and transportation options to accommodate all modes of transportation.  The planning study considered alternatives that would replace the existing Casey Overpass with a new bridge or overhead structure, as well as alternatives that would eliminate the bridge and instead build a new at-grade roadway to accommodate the traffic currently carried by the Overpass.

On March 8, 2012, following substantial public discussion and input, MassDOT announced that it will replace the existing Casey Overpass with a new, multimodal at-grade roadway.  MassDOT is now advancing the engineering of the new roadway to the 25% design phase.
