When CDOT closes Loveland Pass, 99+% of the time this means Highway 6 is closed between Loveland Ski Area and Arapahoe Basin. 99+% of the time Highway 6 between Keystone and A-Basin is still open and, most importantly, A-BASIN IS OPEN. People driving from the Front Range can almost always still access A-Basin by driving through the tunnel and coming through Keystone. When the road between Keystone and A-Basin is closed, it is due to major newsworthy event like an avalanche, rock slide or significant vehicle accident. Rare - maybe once every few years.
Closing the Pass is an inconvenience for everyone. CDOT does an outstanding job with snow removal and avalanche work, but there are times the road needs to be closed. The most up to date info on road status is on CDOT's website, cotrip.org. Unfortunately, re-opening times can be tenuous and hard to pin down.
