At least five people were hurt on Wednesday in a crash involving two semi trucks and several other vehicles on Interstate 70. It happened just after 3 p.m. west of the Eisenhower-Johnson Memorial Tunnel, and I-70 was closed in both directions as a result.

All lanes reopened overnight and traffic was flowing again early Thursday morning. 

The Colorado State Patrol said a semi truck traveling westbound hit another semi truck. Both tractor-trailers then went into the eastbound lanes and hit other vehicles.

One of the people who was hurt had injuries that were described as being life-threatening.
