Graupel (Snow Pellets) Causes Treacherous Travel with Crashes on Bridges on I-294, Route 53 and I-290


VIDEO: Multi-vehicle crash on I-294 over Central Road, crashes on Palatine Road, crashes on Route 53, and an extrication crash on I-290 over Addison Road.

Graupel or snow pellets fell about 10:00 p.m. Friday causing very slick roads. The pellets are extremely slippery when they are fresh on the streets. They often melt and then form black ice, especially on overpasses and bridges on interstates. That’s what happened overnight Friday. Traffic ground the pellets into dangerous ice on the roads. On most of the interstate and expressway, the bridge surfaces were frozen while the roadways were wet.

Palatine Road was immediately closed when crashes started occurring about 1:10 a.m. Wheeling police and Prospect Heights police were on each end of the Elmhurst Road (Route 83) bridge at Wheeling Road and Schoenbeck Road, respectively. Minutes later Glenview Fire Department requested an EMS Box at Interstate 294 in both the northbound and southbound lanes. Firefighter/paramedics from Morton Grove, Mount Prospect, Niles, North Maine, and Park Ridge responded to I-294. Prospect Heights firefighter/paramedics were kept busy on Palatine Road over Milwaukee Avenue.

Some drivers were whizzing by the crash scene at over 55 mph, apparently believing they were somehow immune to the fate of the other drivers that had crashed or were facing the wrong direction in the expressway lanes.

A crash with the center median wall also occurred on Route 53 over Palatine Road and on Route 53 over Northwest Highway — both crashes were in the southbound lanes. Minor injuries or no injuries were reported. At least two crashes also occurred on southbound Route over Interstate 90. The crash on Route 53 over Northwest Highway involved a dark vehicle unattended in a dark area with the rear end of the vehicle sticking out into the inside lane — very dangerous.

An extrication crash also occurred on westbound I-290 over Addison Road, just west of the Route 83 interchange. Both a van and a sedan were faced in the wrong direction at the median wall. The sedan already had it’s roof cut off, and Illinois State Police investigation was underway about 5:30 a.m.
