UPDATE (WKOW) — Two people were injured Wednesday morning in a crash that eventually involved 10 semis.

Troopers were called about 8:20 a.m. Wednesday to a multi-car crash in Juneau County on I90/94 near Mauston, according to a Wisconsin State Patrol news release.

Significant snow had fallen throughout the morning resulting in poor winter driving. At approximately 8:25, a trooper had just taken the westbound exit from Mauston to respond to a crash when he saw two semis behind him.

The rear semi, loaded with metal piping, crashed into the back of the lead semi, loaded with aluminum bales.

The contents of the loads spilled out across the roadway. Eastbound traffic, observing the debris in the westbound lanes, slowed down significantly, which caused another muti-semi crash.

A westbound semi was unable to stop in time for the original crash, swerved across the median and crashed

head on into another semi that was traveling eastbound.

Ten semis were involved in these crashes.

Both westbound and eastbound lanes of traffic were completely blocked by spilled cargo, wreckage, and/or jack-knifed semis.

The interstate was closed for approximately 6 hours.
