Tried an alternate route on the way home. One that would minimize the time on Hwy 17-A. I took Bonnoitt St, Whitesville Rd, and Old Whitesville Rd. All 3 roads have pretty rough tarmac and are 2 lane. I will stick with Hwy 17-A. At least it is 4 lanes and has good tarmac.
The segment I really want to replace is Black Tom Rd. A 2 lane 55 mph race track filled with impatient drivers.
