"The Seaway Skyway is one of the longest bridges over the Saint Lawrence River. It is also one of the most unusual. The Seaway Skyway has a main span that is a suspension bridge supported by Warren pony trusses. However, the bridge also features an extensive approach system composed of a variety of deck truss types. Additionally, the entire bridge has a steel grating deck instead of an asphalt surface, something that is generally only found on historic truss bridges and moveable bridges. It is even more uncommon for a steel grating to be found on a suspension bridge." [BridgeHunter]
This bridge was designed by Modjeski and Masters. [HistoricBridges]

"According to the American Bridge Company, the main towers for this bridge are 243 feet (74 meters) tall. The cable bents are 106 feet (32 meters) tall. The truss spans are 15 feet (4.57 meters) deep and 36 feet (11 meters) wide. The two main cables are 11.75 inches (286 millimeters) in diameter composed of 37 wire rope strands. The main cables have an aluminum filler and wrapped with number nine wire." [HistoricBridges]

None of the street view car drivers were willing to go through customs so I can't get a photo of a tower using street view. Fortunately, one of the many photos Jann took while on a boat was of one of the towers.

HistoricBridges points out that this bridge uses cable bent piers to reduce the height of the anchor piers and that the approach has a curve. One of Jann's photos captures both of these features.

Actually, the bridge does go to Johnstown rather than Prescott. I don't know why everyone else uses Prescott.

The Ogdensburg–Prescott International Bridge is a suspension bridge that spans the St. Lawrence River, connecting Ogdensburg, New York, in the United States to Johnstown (near Prescott), Ontario, in Canada. Opened in 1960, the bridge is a crucial international crossing, facilitating travel and trade between the two countries. It carries two lanes of traffic, with customs facilities on both ends for border processing.Stretching over 1.5 miles, the bridge offers views of the St. Lawrence River and the Thousand Islands region, making it a scenic route for travelers. It links U.S. Route 812 in New York to Ontario Highway 16, which further connects to major Canadian highways. The bridge is part of a broader transportation network, supporting commerce, tourism, and daily travel for residents on both sides of the border. Its role as a key international crossing point has made it an essential component of the regional economy, facilitating the movement of goods and people across the U.S.-Canada border.
Greg Booth: wish they could accommodate cyclists and pedestrians.
Troy Benevitz: I think the sidewalk is still there. Amish teenagers used to cross halfway on foot to meet the Amish from Ontario to find a spouse.

Some comments on the above post implied that it has a steel-grate deck. This view confirms that.
