Friday morning, around 9:15, the train track sensors mistakenly picked up on a rock or other debris near theHighway 425 train crossing, setting off the flashing red lights.
This, in turn, caused the northbound highway traffic control lights to change to constant red, causing a major traffic jam, reaching a quarter-mile to the south.
MPD directed traffic, until city workers brought a four-way stop sign,
Arkansas Midland was notified, and fixed the railroad sensor.
