Oooh, need to check it out! And, I need to rent a vehicle to test the roadway... (don't have my '90 Q45 anymore - 185 with reprogramming electronic limiter).
Once I drove that road towing my travel trailer. I maintained 60-70 mph. In the right lane.
Never again.
The cars, trucks, 18 wheelers, etc. flying by 30-40 mph (at least) faster can make one a little nervous and concerned.
