Center Street Signal Improvements

Two traffic signals in Old Town that were damaged by a severe wind storm in October 2017 were completely replaced and modernized through MaineDOT’s LAP program. In addition to the replacement of these traffic signals, modifications to the geometry of the intersections were also provided to improve both pedestrian and vehicular safety.

project Details

Upgrading traffic safety in Old Town

The City of Old Town, in partnership with the Bangor Area Comprehensive Transportation System (BACTS) and MaineDOT, contracted with Sebago Technics to replace two traffic signals located at the intersections of Main Street @ Center Street and Water Street @ Center Street through MaineDOT’s Locally Administered Project (LAP) program. This replacement was necessary due to a severe wind storm in October 2017 that knocked down multiple traffic signal mast arm structures.

Design elements provided as part of this project included:

  • The complete replacement of two traffic signals being operated by one traffic signal controller. This replacement consisted of six (6) new mast arm structures supported by spread footings due to the presence of shallow bedrock (foundations designed by MaineDOT). Ten (10) pedestal poles were also designed to accommodate pedestrian crossings. Vehicular detection was also upgraded to new non-invasive video detection.
  • The traffic signal controller and cabinet architecture were upgraded to the latest Advanced Transportation Controller (ATC) Standard.
  • Implementation of flashing yellow arrow operation to improve safety of permissive left turn movements at the intersections.
  • Upgrade of all pedestrian ramps to bring crossings up to current ADA compliance.
  • Conversion of a right-turn slip lane being controlled through yield signs to a squared-up signalized lane to improve safety of both vehicles and pedestrians.

Project construction was completed in 2024.
