The traffic signals at the intersections of Independence Street and Kingshighway and William and Broadview streets will be upgraded at night, starting Sunday.
Missouri Department of Transportation crews plan to replace existing bulbs with new 12-inch light-emitting diodes. MoDOT officials said the diodes only have to be replaced once every seven years and use less electricity.
The work will be done from 8 p.m. to 6 a.m., beginning Sunday and running through Wednesday evening. The work will be done at night to minimize the inconvenience to motorists, MoDOT officials said.
