Developing: Crash closed all lanes of I-41 northbound in Slinger in Washington County

SLINGER -- A crash closed all lanes of I-41 northbound near Cedar Creek Road in Slinger in Washington County Tuesday night, Aug. 6.

The left lane of I-41 southbound was also closed.

Deputies were dispatched to the scene around 9:50 p.m. Upon arrival, they observed two people lying on I-41 -- one in traffic and on in a ditch.

One person was pronounced dead at the scene -- the second person was flown by Flight for Life to Froedtert Medical Center. Once there, the transported occupant was pronounced dead.

Officials say it appears both occupants were ejected from the vehicle after making contact with a guardrail on the east side of I-41. For an unknown reason, the vehicle first entered the median, prior to crossing both lanes of traffic and into the guardrail.

Occupants of the vehicle were not wearing seatbelts.

Northbound I-41 was closed for approximately four hours.
