[/caption] The Morrison Bridge was once a wooden truss swing span bridge that opened in 1887 and was the first Willamette River bridge in Portland and the longest bridge west of the Mississippi. The second Morrison Bridge was built in 1905 and wasn’t designed for automobiles so the bridge was again redesigned in 1958 in order to accommodate automobiles. The Morrison Bridge is a draw bridge and has three steel deck truss spans with one double-leaf bascule movable main span and two fixed side spans. the main span length is 284 feet with its total length at 760 feet and is 69 feet above the water line at its center length. Pedestrians and bicycles are allowed on the bridge and it serves as a major commuting tool for pedestrians. The two towers on the south side of the bridge resemble old fashioned airport control towers. There are several great views of the city if you are walking over the bridge. You have great views of downtown Portland or of old town Portland on the north side and the Lloyd district on the east side of the river.
