When you look at the mileage between NH state line and switch in Andover it is probably about 12 miles, than on their own track to Lowell about 10 miles than 4-5 miles to N Chelmsford than about 15 miles to Ayer total about 40 miles with multiple switches to go through AND slow spots on curves, so it really is not worth going 60 mph you would be on and off the throttle.Is the bridge in haverhill still 10 mph.Does anyone have the exact mileage for these segments.
