Council backs temporary 4‑way stop, crosswalk bump‑outs for traffic calming during downtown work

Public works staff outlined two traffic‑calming demonstration projects the council approved June 16 to address safety concerns tied to upcoming downtown construction and detours.

Matt (public works staff) explained the Grammer Road/Grammer Street demonstration will install a temporary 4‑way stop and visual lane‑narrowing devices to slow traffic during the Carter Street detour associated with the RAISE project. The state’s safety engineer and region traffic engineer participated in planning; staff said MaineDOT provided LED flashing signs with a value of about $10,000 and engineering support. The demonstration will be monitored during construction and evaluated for permanence.

Councilors also approved a related demonstration for Route 109 (Main Street) at the two crosswalks south of Front Street. Staff proposed using temporary stand‑up delineators and marked bump‑outs to narrow the roadway so drivers cannot pass a stopped vehicle in the crosswalk, an action intended to reduce near misses documented in the area. Crosswalk signs were installed earlier through a pedestrian safety grant; staff said the bump‑outs are the next evaluation step.

Council discussion addressed neighborhood impacts, possibility of congestion during detours and whether devices should remain after construction. Several members said the measures are appropriate to test during the detour window and can be revisited later. The motion to support both demonstrations passed on voice votes.
