Traffic and construction updates for the Casey Arborway Project

3-Week Look-Ahead: March 18th to April 5th

Since the look ahead covering the period of February 25th to March 15th, the project has continued to advance work on the new north headhouse and upper busway canopy at Forest Hills Station.

Motorists are reminded that eastbound (towards Franklin) and westbound (towards the Arboretum) left turns off the Arborway at the intersections of South Street/Arborway and Washington Street/Arborway are now permanently prohibited. These movements will now be permanently handled by the eastern and western median U-turns. The only exception to this is the westbound left turn at Arborway/Washington Street which is available to general purpose traffic as directed by the electric sign mounted on the signal controlling the Arborway westbound approach. Drivers of private cars using this left turn when the approach is signed for buses only may be subject to fines and assigned moving violations. Additional warning signage addressing this issue has been installed and is subject to police enforcement. As of the period addressed by this look ahead, enhanced traffic enforcement by the State Police is in place.

Motorists are also reminded that the northbound (towards Green Street) right lane of Washington Street west (towards the Arboretum) of Forest Hills Station is now an active travel lane. Taxis are now operating from their permanent location on the Arborway north of Forest Hills Station. Private vehicles, Lyfts, Ubers, etc. are prohibited from stopping in the active travel lane. This will be subject to traffic enforcement during the three weeks covered by this look ahead and beyond. Regulatory signage to this effect has been placed and will be subject to police enforcement

  • Work at the new northern (towards Green Street) headhouse will focus on installation of electrical elements and elevator components.
