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 six spans and a main span of 350.75 metres (1,150.8 ft) totaling 2.4 kilometres (1.5 mi) across the Saint Lawrence River and Saint Lawrence Seaway.[2] The bridge is owned and operated by the Ogdensburg Bridge and Port Authority, which also owns and operates Ogdensburg International Airport, the Port of Ogdensburg-Marine Terminal Facility, Commerce Park, the Port of Waddington, a medium-heavy industrial park and two short line railroads. The Ogdensburg Bridge and Port Authority is a New York State public-benefit corporation.[3][4]


The 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.[5] 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 US interstate highway.[6]

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.

On the US side, the bridge connects to New York State Route 812, which connects with New York State Route 37 a few blocks from the southern end. Route 812 joins Route 37 west into Ogdensburg. It then goes south to Village of Lowville in Lewis County. Route 37 continues west to a fork at Morristown, N.Y. where Route 12 picks up to Alexandria Bay and Interstate 81.

Border crossing[edit]

The Ogdensburg–Prescott Border Crossing connects the cities of Ogdensburg, New York and Johnstown, Ontario at the Ogdensburg–Prescott International Bridge. The US border inspection station was built in 1960. The inspection canopy was replaced, and the building significantly upgraded and expanded in 2004. The Canada border station was replaced in 2012.


On 1 September 2015, the Ogdensburg–Prescott International Bridge made headlines after Prime Minister Stephen Harper posted a video to his Facebook page standing in front of the bridge and the Port of Johnstown.[7] The video was supposed to be a congratulatory video about the shipbuilding industry in the Halifax harbour in Halifax, Nova Scotia, however upon its release, locals of Halifax noticed inconsistencies with the scenery compared to that of the Halifax harbour and began to question where the video was actually shot. By 5 September, viewers had determined the video was actually shot in Johnstown, Ontario based on the quick shot of the port in the background, which was unmistakably the Port of Johnstown. Viewers then accused Harper of trying to pass off the scenery as the Halifax harbour due to the undeniable similarities between the Ogdensburg-Prescott bridge and the A. Murray MacKay Bridge in the Halifax harbour.[8]
