All reports I have read says it’s open. There is bridge across Salt creek a few miles west of the tunnel that is not passable and may be a while before it’s repaired. The recommended detour is on 40 hiway, however there is a gravel alternative if you don’t like road riding. Scroll down the forum a few posts there is a thread discussing this issue and the detours.
