[/caption] The St. Johns bridge is the Willamette Valley’s only major suspension bridge but at the time of its opening in 1931 it had the longest span of any suspension bridge west of Detroit’s Ambassador bridge. the main span length is 1,207 feet and the tower height is 400 feet above the water. The St. Johns is also the tallest bridge in Portland. There is pedestrian access for both joggers and bicycles and you have a pretty nice view of the Port of Portland and downtown Portland at about the mid point of the bridge. It’s worth making the walk and make sure to bring your camera and tripod. You can get a good view of the bridge from either side of the river. Forest Park, on the west side, has several vantage points and the St. Johns neighborhood, on the east side of the river has great views from the park. You also have a good chance of seeing Osprey, bald eagle or Hawks near the bridge.
