Motorists headed west on Interstate 70 near the Eisenhower Tunnel were at a standstill for nearly an hour and a half after several cars went off the interstate just west of the tunnel Sunday night.
CDOT said they weren't sure when they could reopen after the 6 p.m. wreck near mile marker 215, and that their main goal was working to clear the roadway after five cars went off in just 30 minutes.
The eastbound lanes weren't slowed.
CSP commented on 9NEWS' Facebook Live telling drivers to slow down.
"Slow down. Need to hear it again? Slow down," they wrote.
