The I-94 eastbound off-ramp at Highway 100 was closed early Monday morning after a crash, according to Waukesha County Sheriff's Office.
The sheriff's office says the incident was due to a chase that started just before 12 a.m. when they observed a vehicle traveling at a high rate of speed on I-94 near Moorland Road.
The chase came to an end when the fleeing vehicle crashed into a median on Highway 100 over I-94.
The 20-year-old female driver was transported to the hospital along with another 20-year-old female passenger and a 19-year-old male passenger.
The eastbound off-ramp to Highway 100 was shutdown for several hours, as well as the north and southbound lanes.
Investigation into this incident is underway.
