Two people are confirmed dead in a crash involving a semi and a car on Interstate 94 in St. Croix County, Wisconsin. Eastbound traffic was diverted off the Interstate to allow emergency vehicles and helicopters access to the scene.

Authorities say the driver lost control of his vehicle on the ramp from southbound 280 to I-94 in St. Paul early this morning. The driver of the vehicle then fled the scene on foot, leaving the car behind.

Authorities shut down lanes on the highway and traffic was backed up for miles because of a "jumper" on a bridge just east of the Lowry Tunnel.

Transportation officials will shift traffic Tuesday night into Wednesday morning as the center lanes on that segment of interstate reopen and the outside lane closes.

The State Patrol shut down I-94 eastbound in the Twin Cities for two hours after reports of a man threatening to jump from an overpass. Kare 11 reports police spoke with the man and took him into custody.

Road construction may snarl traffic this weekend, as all eastbound lanes of Interstate 94 close for crews to lay pavement between Highway 55/Hiawatha Avenue and Highway 280 in Minneapolis. Interstate 35W in Arden Hills is closed in both directions between Interstate 694 and Highway 10 so crews can demolish the old County 10 Bridge. The closures continue through early Monday morning.
