There are gaps, you are allowed to cross Route 6 but not ride on it.
Some gaps that are state roads, there are plans to close the gaps, but what people have done is ride the short sections to access another legal road. The only time I hear of problems with the cops is if your not wearing a helmet, eye protection and such.
Ive ridden up to the NY border and only had to make one jump across a non-legal road.
