Casey Overpass Project

Upcoming Work

May 9 - Permanent Closure Process Begins

During the weekend of May 9th, the westbound (towards Jamaica Pond) lane of the Casey Overpass will close to traffic. By the time of the closure, temporary lanes to the north of the Overpass and the temporary signals which match them will be fully operational and ready to receive traffic.

During the weekend of May 16th, the Casey Arborway Overpass will close permanently. Demolition will begin during the week of May 18th.


Eastbound (towards Franklin Park and Dorchester) traffic will be split at the western (Arnold Arboretum) end of the Overpass. Traffic seeking to access South Street, Forest Hills Station, and points south, will bear to the right, making a right turn onto South Street at the bottom of the ramp. Left turns onto South Street northbound will not be permitted. Eastbound through traffic for Shea Circle, Hyde Park Avenue, West Roxbury Municipal Court, Franklin Park, and Dorchester will bear left onto the eastbound temporary roadway. Eastbound right or left turns to South Street in either direction will not be permitted. Right and left turns at Washington Street will be open to traffic. Generally speaking, north and southbound movements along Washington Street and South Street will remain as they are today for this phase of construction. The southbound exit of Forest Hills Street into Shea Circle will remain closed to ensure the safety of the traveling public.


The Southwest Corridor Path will terminate and cyclists will need to turn left or right based on their desired destination. Cyclists seeking to access South Street, north or southbound should bear to the right. Cyclists with destinations on Washington Street or to the east should bear to the left. These temporary connections are shared with pedestrians. We ask cyclists to reduce speed and exercise additional caution when using the temporary connections. Cyclists may also use the sidewalk connection along the northern edge of the temporary roadway adjacent to the Arborway Yard MBTA bus maintenance facility. This space is also shared with pedestrians

In areas signed accordingly within the work zone, bicyclists may use the full lane if they wish to travel on the road. If they do so, they must comply with all signs and signals.


Pedestrians traveling from points east of the project area will traverse Shea Circle at the existing crosswalks provided today. A sidewalk will be provided along the northern edge of the temporary roadway adjacent to the Arborway Yard MBTA bus facility to provide a connection to Forest Hills.

Signalized crosswalks will be present on the north and west sides of the intersection of Washington Street and the temporary roadway. Signalized pedestrian crossings will also be provided on the northern and western sides of South Street and temporary roadway intersection. Existing signalized crosswalks south of the Overpass on South Street and Washington Street will be maintained during this phase of construction.

All work is subject to weather conditions.
