Hi - My wife and I did a preview drive (yes in our car) of part of the Pacific Coast Highway south of Monterey. We can across two single lane restrictions due to road repair work. The first was on Map 47, near Rocky Creek. The second was on Map 48, near Lucia. There is a bike button to push for the lights, presumably making them longer. Both spots were extremely constricted. The road width appeared to preclude a car and ANYTHING else coexisting on the lane - in other words, no passing room, from a car approaching from the front, or the rear.
What is the community experience with riding through this? For instance, on Monday afternoon, the Rocky Creek stop was not staffed, and relied on light control, causing me to wonder if a heavily loaded bike would actually have time to get through the uphill toboggan run without getting creamed. The second stop, near Lucia, was staffed, shorter, and more likely to be successfully negotiated.
