Casey Arborway - Look Ahead

3-Week Look-Ahead: April 3rd to April 21st​


Through June 2017, all Orange Line train service will arrive and depart from the western side of the Forest Hills platform (towards the Arboretum). Normal two track operation will continue immediately north of the station.

Throughout the period covered by this look-ahead, work will take place below ground at Forest Hills Station to install electrical components and support structures associated with the jet fans and new head-house.

Likewise, over the course of all three weeks, excavation and construction will take place for the Morton Street/Orchard Hill Road wall.

During the week of April 3rd, operations will concentrate on the following:

  • Relocation of water line under the permanent westbound Arborway.

  • Installation of elements of the 48” MWRA water line near Shea Square.

  • For the area west (towards the Arboretum) of South Street along the mainline Arborway:

  • Installation of drainage from the westbound Arborway into Toole Square and South Street.

  • Installation of traffic signal and street lighting conduit at the intersection of South Street and the Arborway.

  • Reconfiguration of traffic signals in preparation for Stage 3A.

  • Demolition of ventilation elements original to Forest Hills Station which conflict with the new roadway alignment.
