First Street signal malfunction in Ketchum requires timing work
KETCHUM – A recent malfunction with the underground traffic detection for a traffic signal at the intersection of Main Street (Idaho 75) and First Street in Ketchum has required a timing change, the Idaho Transportation Department announced. The signal remains in operation with a specific time allotted for traffic in each direction.
ITD personnel initiated the signal timing change on Thursday (April 12). The signal will continue to operate by timing until a new system of traffic-detection cameras can be mounted from the signal poles in the coming weeks.
Drivers are urged to use caution through the intersection and watch for other drivers unaware of the signal changes.
In the past, the signal changed to allow traffic to cross from First Street following detection from an underground system of magnetic “loops” or wires placed in the asphalt roadway. The loops were installed with the signal in 1996 and lost connectivity with the signal control cabinet recently. Without the detection loops, traffic on First Street was not recognized by the control cabinet.
