We went up Glacier Point road and we did not have to stop and wait, just drive slow for about 1/4 mile. Same on Hwy 41 at 2 spots, one near Wawona visitor center and one on 41 just south of the park entrance. Same situation both times, we had to drive slow through the construction zone, but did not have to stop and wait. Virtually no delay. Though as it gets later on and more people come to the park, lines may form.
