This link points to a large pdf file with annotations by me describing many of the features of the western end of the new Casey Arborway:
The western end of the project has been one of the last to be designed. Highlights of the plan here include:
- New sidewalk and off-street bike path along the northern side of the Arborway west of South St.
- A pedestrian-activated crosswalk providing access to the Forest Hills Gate of the Arboretum from the north.
- There will be no westbound left turns onto Washington Street. This change of direction will be accomplished by the western "Bow-Tie" U-turn at the Forest Hills Gate of the Arboretum. A turning apron accommodates wide-turning vehicles. Westbound traffic only stops for turns and pedestrians.
- New trees soften the large existing retaining wall along the Arborway Hillside.
- A new, lower retaining wall separates Arborway Rd's grade differential from the Arborway proper at Hampstead Rd.
- Off-street bike paths and sidewalks along eastbound Arborway.
- New boulevard trees (Red Oaks) throughout
- New Northern plaza with MBTA Head House, programmable space, bike paths, permeable surfaces for drainage.
- Revamped southern MBTA plaza
- Mid-block pedestrian crossing eliminated
