About This Project

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 the Jamaica Plain area of the City of Boston. The Overpass is located directly adjacent to the Forest Hills MBTA Station. (see locus map).  The area of the Overpass serves many neighborhoods and traveling 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 original design flaws.  The structure has deteriorated beyond the point where it can be effectively maintained and will be replaced with a new, at-grade boulevard to be known as the Casey Arborway, between spring 2014 and fall 2016.  Replacement is being funded through the Patrick-Murray Accelerated Bridge Program (ABP) which seeks to reduce the number of structurally deficient bridges in the Commonwealth through repair or replacement. 

Project Overview

DESIGN PROCESS

On March 8, 2012 following substantial discussion and input from both the community and Working Advisory Group, MassDOT announced its decision to replace the existing Casey Overpass with a new, multimodal at-grade roadway.  As of the summer of the 2013, the project has passed many significant milestones, including receipt of a MEPA certificate for the project in January 2013 and the 25% design public hearing in February 2013. 

 As of November 2013, the Plans, Specifications and Estimate (PS&E) drawings for the project have been submitted to MassDOT. A general plan of the corridor as the new Casey Arborway can be seen here. At this time the design for the project is generally complete.  MassDOT is currently reviewing the finalized design with particular attention to design details regarding landscaping and pedestrian accommodations. MassDOT and its design team have also concluded their work with the Design Advisory Group  (DAG). A closing meeting of the DAG was held on November 19th to provide this group with a final overview of the 100% design. Both DOT and its design team want to express their thanks to the membership of the DAG for their hard work over the course of the design phase.  Members of the DAG who began with the Working Advisory Group (WAG) in 2011 are especially thanked for their long commitment to the project.   It is currently anticipated that the project will be put out to bid in January 2014 with construction to begin in spring 2014.  MassDOT encourages you to become involved in the project as it transitions from design towards construction.  Community members with specific ideas about the construction period or who would like to join the stakeholder database to receive updates during the construction phase are encouraged to contact Michael Trepanier Community members are reminded that members of the design team can be made available for neighborhood or stakeholder group briefings upon request.

PLANNING PROCESS

In March 2011, the Massachusetts Department of Transportation (MassDOT) initiated a study of alternatives to replace the existing Casey Overpass. The study worked 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.

As part of this process, MassDOT formed a Working Advisory Group, made of representatives of local neighborhoods and organizations that will be effected by the outcome of the Casey process. This group met regularly from March 2011 through November 2011. To review the materials developed by and for the Working Advisory Group members, please visit the project meetings page.

what's new


As of the fall of 2013, the PS&E drawings for the Casey Arborway have been submitted to MassDOT and a final DAG meeting to share the changes made since the August DAG meeting has been held. The August DAG meeting detailed changes to the design made in part based on community commentary received at the 75% design public information meeting held this past July. At this point, the design phase is largely complete and construction is expected to begin in the spring of 2014. To keep up with the project during the construction phase, please join our stakeholder database; please contact Michael Trepanier.
