A new traffic signal at the intersection of Mountain Avenue and Great Road is now in operation.

“This new traffic signal will help drivers make safer turns and help provide a safer pedestrian and bicycle link, connecting the Mountain Avenue path to the Johnson Trolley Line path,” said Mayor Liz Lempert.

Proposed in Princeton’s Community Master Plan since 1996, the new signal operated for the first five days in yellow “caution” flashing mode to Great Road and a red flashing “stop” for the Mountain Avenue approach. Signage and an electronic message board were in place on Great Road during the flashing operations to inform the drivers of the traffic pattern change.

Starting Wednesday, December 21, the signal will be fully operational. The overall improvement project is anticipated to be completed in the Spring of 2017 with the resurfacing of the intersection and the final surfacing of the paved pathway connecting to 300 Elm Court on the west side of Great Road.
