MORTON — A semi driver lost control of his vehicle Tuesday afternoon on the ramp between Interstate 155 and westbound Interstate 74, shutting the ramp temporarily.

The driver was traveling northbound on the I-155 ramp about 4:45 p.m. when he lost control of his vehicle for unknown reasons, Illinois State Police said in a news release.

The semi rolled onto its side, and the ramp is closed to other traffic.

Motorists trying to use the ramp are being routed onto I-74 eastbound to turn around and re-enter the interstate westbound at exit 102 in Morton.
