Dec 03, 2008 — The "rooftop highway" is almost mythical in northern New York. The idea of an Interstate linking Watertown and Plattsburgh, through Gouverneur, Canton, Potsdam, and Malone, has been bouncing around since the 1950s. It's seen as a key to economic development in the North Country. New York's department of transportation estimates the whole project would cost $2 billion and take decades to build. So the DOT is taking public comment on a new plan to take the smallest of steps forward--a passing lane here, decongesting intersections there, maybe even a bypass. 75 people came to last night's meeting in Canton. Few were pleased with what they heard. David Sommerstein reports.
