Workers from the Idaho Transportation Department and the City of Lewiston will modify the existing signal at 18th Street and Main Street in Lewiston starting tomorrow (April 21) to improve traffic flow.
The modified signal will feature flashing yellow arrows.
“This change improves drivers’ mobility by allowing them to turn left after checking for pedestrians and oncoming traffic without waiting for a solid green arrow,” ITD Traffic Engineer Jared Hopkins said.
Work will start at 8 a.m. and will last for several hours, during which time drivers will be directed to treat the intersection as a four-way stop.
