The Ship Canal Bridge is a double-deck steel truss bridge[1] that carries Interstate 5 (I-5) over Seattle's Portage Bay (part of the Lake Washington Ship Canal, after which it is named) between Capitol Hill and the University District.
Construction was completed in 1961 and the bridge opened to traffic on December 18, 1962.
It was the largest bridge of its kind in the Northwest when it first opened.
The bridge is double-decked, with the upper deck carrying traffic in both directions and the lower deck (the express lanes) carrying traffic southbound in the morning and northbound in the afternoon.
