A civic planning organization is proposing a trail network connecting New York, New Jersey and Connecticut.

The Regional Plan Association has released a report proposing connecting 1,650 miles of biking, hiking and walking trails in the three states.

The plan describes three routes extending from New York City using existing trails that would need to be connected.

One route would connect Manhattan to the 750-mile cross-state Empire State Trail proposed by Gov. Andrew Cuomo early this year. The Empire State Trail would connect existing trails into one network from Buffalo to Albany and northward to Canada.

A proposed day trip by bicycle would go from Grand Central Terminal to the Mohonk nature preserve in Ulster County.

The report doesn't estimate the cost of completing its proposals.
