Just a heads up to anyone planning to ride this route, the entire surface is a mess at the moment. Your options are fresh tar or deeply grooved de-surfaced rock.
Rode through there this morning, they are making nice progress and it is very passable at the moment (no fresh oil, not grooved just that tar-papery stuff they lay down - not sure what it really is) but I am sure they will be pouring asphalt soon.
