Columbus considers upgrade to traffic signals

COLUMBUS, Neb. (AP) - Columbus is considering upgrading its aging downtown traffic signals, but one council member thinks officials should take a larger look at whether some of the traffic lights are even necessary.  City staff told council members last week that traffic signals need to be modernized because some components for the aging system are no longer available. City Engineer Dave Goedeken says new controllers also are needed to stop some lights from malfunctioning.  Council President Ron Schilling asked whether downtown needs so many traffic signals. He says some should remain along busy streets, but others seem to have little value.  City staff says they'll consider a study that would determine whether stop or yield signs, or no control device at all, could work just as well.
