All five passengers in that vehicle were transported to UW Hospital, including one with life-threatening injuries.

No names have been released at this time.

The state patrol says one of those crashes involved three cars heading eastbound.

Two vehicles were slowing down for a crash across the median in the westbound lanes when 47-year-old Karl Gallagher of Genoa, Ill., hit one of the cars and caused the crash.

A 7-year-old passenger in Gallagher's vehicle had non-life threatening injuries.

We're still waiting on information for the other crashes that happened in that area around the same time.

Dane County dispatchers say three crashes about an hour ago called for Med Flight and a number of ambulances.

The interstate is shut down both east and westbound near the Highway 51 exit for Stoughton -- that's to allow a landing zone for Med Flight.

The state patrol says at least one of these crashes has injuries reported.

We'll have the very latest on these crashes on NBC15 News at 10.
