1 person dies in crash on NB I-25 after Castle Rock Pkwy. heading toward Happy Canyon Rd. Tuesday

CASTLE ROCK, Colo. — A deadly crash on northbound Interstate 25 after Castle Rock Parkway on the way to Happy Canyon Road backed up traffic Tuesday morning, CSP confirmed.

The wreck happened just after 6 a.m. Tuesday when a driver hit and killed a person who was out on I-25, according to Colorado State Patrol's public information officer Trooper Gabriel Moltrer.

All lanes were temporarily closed when the crash first happened, but one lane reopened at 6:25 a.m., CSP told Denver7.

Then, another lane reopened by 7:05 a.m. to relieve some of the bottleneck, Denver7 Traffic Expert Jayson Luber observed.

Drivers were delayed past Founders/Meadows Parkway to Plum Creek Parkway by that time though, because of the reduced number of lanes open, Luber said.

The delay could last for over an hour, Luber estimated at 7:05 a.m. Tuesday. And by 8:40 a.m., the wreckage was completely cleared and all lanes of northbound I-25 reopened. However, there were still some delays leftover from the bottleneck.

Luber recommended Happy Canyon and Daniels Park Road as alternates. Santa Fe could get crowded before too long, according to Luber.

Douglas County Sheriff's Office was also on scene to help Colorado State Patrol and tweeted that drivers should be aware of multiple emergency responders in the area.

Moltrer told Denver7 how the fatal auto-pedestrian wreck happened is still under investigation.
