Thousands of shoes left on Florida highway

State troopers are looking for a charity to take thousands of shoes that were dumped on a Miami expressway, tying up rush hour traffic.

Lt. Pat Santangelo says the Florida Highway Patrol received a call about the shoes this morning.

Santangelo says he's not sure where the shoes came from. There were no signs of a crash and no one stopped to claim them. He says he hopes someone will take them because he doesn't want to send them to the dump.

Workers using a front-end loader and a dump truck were able to quickly clear at least one lane by sweeping all the shoes to shoulder, but delays were expected until they could all be removed. - chron

Someone dumped thousands of shoes all over the southbound lanes of Palmetto Expressway. There were a wide variety of shoe types: slippers, sandals, and work boots. The piles of shoes on the highway disrupted traffic for hours. ... The shoes will be picked up from the field where they were moved to by Soles4Souls, a nonprofit group in Nashville, TN, which distributes shoes to the needy. The founder of the group, Wayne Elsey, said "We throw nothing away. Right now they'll probably go to Haiti." Florida Highway Patrol Lt. Pat Santangelo said "No witnesses have come forward, but whoever is responsible would be charged for the cleanup." - ac

Police said thousands of work boots, bath slippers, tennis sneakers, beach sandals, even pairs of in-line skates, all inexplicably materialized shortly before 8 a.m. on the busy roadway, disrupting traffic for hours. A private contractor had to be hired to pick up the sea of soles and deposit them at an empty field near the U.S. 441 exit off I-95. - mh
