Construction Page

Commencing February 24th and continuing through the end of September 2015 it will be necessary for the GLX contractor, White Skanska Kiewit (WSK), to close the southbound travel/bike lane and west side sidewalk between School Street and Walnut Street to vehicular, bike, and pedestrian traffic for the purposes of erecting a temporary utility bridge. Residents will be able to cross Medford Street over to the east side sidewalk to cross over the bridge and the westbound lane will be re-configured to allow for 2-way vehicular and bike traffic.

The section of road and sidewalk will be closed to vehicular, bike, and pedestrian traffic starting on Tuesday, February 24th at 8:30 AM and will not reopen until the end of September 2015. Update: Due to ongoing work and coordination with utility companies, it was necessary that the Medford Street closure be extended. It is now estimated that the Medford Street closure should be re-opened in the first quarter of 2016.]

Signage providing direction and detail police providing assistance will be available to assist vehicular, bike, and pedestrian traffic.
