Island Electric will be upgrading traffic signals in Ketchikan Monday through Thursday, starting at 7 p.m each evening.
Work will begin at the intersections of Tongass Ave and Washington Street, and Tongass and Carlanna Lake Road.
The upgrade is related to a recent decision by the Alaska Department of Transportation to install flashing yellow lights to traffic signals in Southeast cities. The flashing yellow lights are meant to show when it’s safe to turn left.
In addition to the two upgraded lights in Ketchikan, one will be installed in Sitka, and eight will be added in Juneau. The capital city already has three flashing yellow lights.
Below is a link to an animated illustration of how the lights work.
