Clinched County Route G17 today and just got my photos posted:

Oddly G17 isn't even signed from CA 1 all the way southeast to Davis Road for some reason. The rest of the signage south to G16 at the Elm Avenue Bridge is generally pretty poor and you have to look for it. River Road in particular was difficult to keep following since the natural grade runs over the Salinas River on Chullar River Road with no reassurance shield. South from Chullar River Road G17 is in generally bad shape until it becomes Arroyo Seco Road. I did manage to find a decent vantage point of the Elm Avenue Bridge for once. I'll post the road blog here once it is done, I might couple it with the ruins of Fort Ord.
