Ogdensburg–Prescott International Bridge

The Ogdensburg–Prescott International Bridge, also known as the St. Lawrence Bridge and the Seaway Skyway, is a suspension bridge connecting Ogdensburg, New York in the United States to Johnstown, Ontario (a few kilometres east of Prescott) in Canada. Designed by Modjeski & Masters and completed in 1960, it has 6 spans and a main span of 350.75m totaling 2.4km across the Saint Lawrence River and Saint Lawrence Seaway.AccessibilityThe Ogdensburg–Prescott International Bridge allows for both passenger and commercial vehicles to cross the Canada-United States border; neither cyclists nor pedestrians are permitted to cross this bridge. The bridge is a very popular border crossing for passenger vehicles due to its proximity to Ottawa on the Canadian side, with 410,000 vehicles crossing in 2011 alone. The bridge was designed for heavy loads and has a weight capacity of 105,000 pounds. The weight limit easily accommodates semi-trailer trucks. This bridge, however, does not see as much commercial traffic as the nearby Thousand Islands Bridge, as it is not a direct route to any American interstate highway.On the Canadian side, the bridge connects to Highway 16, a highway which interchanges with Highway 401 and Highway 416 that continues north to Ottawa.
