The Traffic lights at Belt Highway and Frederick Street are back in working order Wednesday afternoon.

The traffic lights starting malfunctioning Tuesday and Wednesday forcing law enforcement and MoDOT to control traffic at the intersection.

Crews found the signal’s internal wiring at the main box had corroded due to moisture. This caused the lights to go into default mode and flash red.

The intersection was treated as a four way stop for motorist while the lights were out of service.  The temporary traffic control backed-up traffic at what is one of the busiest intersection in St. Joseph.

MoDOT’s Northwest District office announced  Wednesday afternoon the light’s had been restored to working order.  Some time will be taken to verify the timing is set right on the traffic signals.
