Original story

Summit County Sheriff Jaime FitzSimons said Interstate 70 is experiencing closures following a multi-vehicle crash near mile marker 207 around roughly 1:40 p.m on Friday, Feb. 14.

FitzSimons said I-70’s westbound lanes are closed near the Eisenhower-Johnson Memorial Tunnels and that the interstate’s eastbound lanes are closed at Exit 205 near Silverthorne and Dillon, as of 1:40 p.m.

U.S. Highway 6 over Loveland Pass is closed in both directions due to “safety concerns” as snowfall is accumulating on highways and roads across Summit County.

Summit County is currently under a winter weather advisory as double-digit snowfall is expected through Sunday. The winter storm is coinciding with Presidents’ Day weekend, which is the second busiest winter holiday in Colorado, and officials say traffic is expected to be heavy while road conditions will be dangerous.
