Denny Substation Program Update

Beginning in mid-October, crews will be working on a transmission line in E Denny Way and Denny Way. This work is necessary for the Denny Substation to tie in to the transmission line that runs underneath Denny Way.

E Denny Way Westbound Closures


Beginning in mid-October, crews will be working on a transmission line in E Denny Way between Summit Ave and Bolyston Ave E for approximately ten weeks. The first phase of this work involves excavating a large pit to expose the transmission line. The second phase of work involves freezing the oil-filled transmission line, splicing in new cable, filling the new line with oil, and restoring the street.

In order to complete this work, crews will close the westbound lane of E Denny Way between Belmont Ave E and Boylston Ave E beginning as early as October 17 for approximately 10 days (Phase 1). Beginning as early as October 28, they will extend the closure area to the west for approximately 2 months (Phase 2). Eastbound access on E Denny Way will be maintained during both phases.
