DENVER — Northbound I-25 is back open near Larkspur after several cars hit a piece of metal and a semi-truck overturned.

The Colorado Department of Transportation reported the crash just after 9 p.m. on I-25 north between the exit for Upper Lake Gulch Road and Spruce Mountain Road.

Colorado State Patrol said there was a piece of stray metal on the road, and several cars hit it.

A semi-truck also overturned during the incident.

CSP did not provide a total number of vehicles involved.

One person is being medically evaluated, but details on the severity of the injuries were not provided.

Two right lanes were blocked for some time, but the interstate was fully reopened by about midnight.
