A semitrailer truck crashed through the concrete median on westbound 94 at the Lowry Hill Tunnel earlier this morning and that has the left and center lanes blocked on eastbound 94.

Several vehicles are involved in the crash, which happened shortly after 5:30 a.m.

One vehicle that was heading eastbound rolled over and landed on the embankment on the right side of the freeway. Debris is littering the road on both sides of the crash.

Eastbound traffic is already stacked up to before 7th Street. Look for backups to develop on 394 as the rush hour gets busier.

Westbound traffic is getting by in the two right lanes.

There is no immediate word of injuries, but ambulances and first responders are on the scene.
