Part of the Marquette Interchange is closed due to a fatal motorcycle crash on Sunday, June 14.

The initial WisDOT notification for the accident came in just after 10 a.m.

The system ramp that goes from I-94 East to I-43 North (and part of the Kilbourn Tunnels) is currently closed, with MCSO squad vehicles blocking access.

The Milwaukee County Sherriff's Office says deputies and other first responders are tending to a fatal, single-vehicle motorcycle crash, and that the circumstances are under investigation.

MCSO says it will provide an update when the freeway opens back up.
