In an exciting announcement CPR News published the article "After years of repairs and careful restoration, historic Alpine Tunnel Road reopens near Pitkin." The article lauds the multi-year work done to repair the rock wall damaged in 2016 by an avalanche. The damage closed the road for vehicles to the Alpine Tunnel station complex and the west portal for roughly eight years. During that time, vehicles needed to be parked just a little upgrade of Sherrod Loop. Finally, as the article states, "After years of repairs, a historic road deep in the Rocky Mountains has finally reopened — just in time for fall."
But the news is a bit tempered. If you read to the end, you come across this sentence: "There still is one hiccup when visiting the historic district: a large boulder that’s a little less than a mile from the historic tunnel. Visitors can park at the intersection of the Alpine Tunnel Road and Williams Road, and walk the rest of the way."
What???
There is no other info on the boulder and the circumstance surrounding it. But, essentially, you can at least drive over the old South Park grade eastbound past the former parking spot above Sherrod and, presumably, past the rock wall, but not much farther.
