I drove the road to McCarthy about 10 days ago with a half ton Ford F150, had no problems. The folks at air service told me it was about a 2 1/2 hour drive and that was about right. Met a Honda Civic and when I got to the walking bridge was surprised at the variety of vehicles parked there. Living on a farm I have found that the standard P rated tires that come with these half ton pickups do not stand up to the rocks and will have breaks in tires. Switching to the Load E rated tires pretty much eliminates tire trouble. I was passed by a Shuttle Van and it was moving pretty fast. 60 miles-2 1/2 hours, figure it out, just drive slow and enjoy the scenery. While filling with gas at Chitnia a local person told me the road was in the best shape he has seen it for years.
