Make it 8' so police could pass and restrict it to golf carts, 4 wheelers and emergency vehicles as is the law. that would be pretty cheapif we used soil stabilization techniques. Before we never wanted that graded because we knew that when we broke the hard crust and got into loose sand we would have big problems. With bigger, heavier vehicles someone decided to grade to accommodate the illegal traffic instead of doing the right thing and demand enforcement of the existing vehicle ban on North Ambergris as a first solution and then build the 8' road for super light vehicles. Then change the law to accommodate the heavier traffic as soon as the road and bridge will support it but not before. Realize that the road can never be a practical way to get construction materials north as all trucks would have to pass through town and the bridge will not support it for long at all.
