Sharon: The tunnel is closed unfortunately. There is a well marked detour to get up and over the tunnel but you will be walking your bike both up and down due to steepness and not great riding terrain. With gear, the extra weight will make this slightly more difficult but certainly can be done with patience.
Scroll through the forum here, there’s been quite a few posts over the last couple months about the detour that have better details than my post here.
