Veterans Memorial Bridge remains unlit because of mayfly hatch

Mayflies have been hatching along the Susquehanna River, and the lights on the Route 462 bridge have been shut off for more than a month now to help keep their carcasses off the structure.

Several hatches have been seen this year, said Mark Stivers, Columbia borough manager. A recent one left the mayfly carcasses an inch and half deep at Columbia Crossing.

The insects are attracted to the lights on the bridge, and piles of bug carcasses littered the structure.
