Traffic signal changes set along bypass

-A A +A

Traffic signals at College Street and St. John Road along the U.S. 31W Bypass in Elizabethtown are being reprogrammed for variable phasing, allowing better traffic flow, officials said. The term “variable phasing” refers to a signal pattern only being used at specific times, based on traffic volume.

Beginning Thursday, motorists traveling on the bypass will be able to make a left turn when given a flashing yellow arrow at each of these intersections. This signal will not be used during peak traffic hours. During heavy traffic hours of 6:30-9 a.m. and 3-7 p.m., motorists must wait for a green arrow to turn left.

Department of Highways traffic crews implemented variable phasing at the intersection of U.S. 31W and Ky. 447 near Kohl’s in November 2011 to decrease potential for angle collisions. Data gathered since then show fewer wrecks at that location. Some signals along Ring Road also are programmed with the flashing yellow arrow feature, but they are not variable.
