Northbound Interstate 25 is closed in between Monument and Larkspur because of a fatal crash near the Greenland exit, the Colorado State Patrol said Wednesday.

Editor’s note: Northbound lanes of I-25 have since reopened following the fatal crash. 

At least one person was killed in the crash about 5 p.m., said Patrol spokesman Gary Cutler. Both of the northbound and southbound lanes of I-25 are closed at County Line Road, Cutler said. Authorities advised motorists to avoid the area.

The Colorado State Patrol account tweeted at 5:39 p.m. that the northbound closure is expected to be 3-4 hours. Southbound I-25 is now open but expect heavy delays.
