LANCASTER, Pa. (AP) – Authorities say a swarm of mayflies blanketed a Pennsylvania bridge, prompting them to close it after a series of motorcycles crashed because of the insects.
Police in West Hempfield Township in Lancaster County said the Route 462 bridge between Columbia and Wrightsville was shut down at about 10:30 p.m. Saturday.
The LNP newspaper reports that the mayflies swarmed around the lights on the bridge and then fell to the ground, making piles several inches deep on the roadway.
Fire police blocking traffic on the Wrightsville side of the bridge attributed the swarm to four motorcycle crashes.
Officer Brad Rohrbaugh said the bridge was reopened sometime before 6 a.m. Sunday.
