I'm thinking of exploring the Old Coast Rd from Bixby Bridge to Big Sur. On my Delorme SA map it shows a break in the road that it marks as a trail. On my Delorme Topo it shows a complete road. On this map I have shown the SA version and circled the trail in the road. Is this a passible area with a 4x4 or must I go out to Hwy 1 and cut around it?
