-Marquam       MARQUAM BRIDGE BRIDGE FACTS Type: Fixed Double Deck Continuous Steel Truss At mile marker: 13.5 Overall length: 1,043'-8" Owner: State of Oregon        Designed by the Oregon State Highway Department Bridge Section, the Marquam is a through-truss, fixed bridge with a suspended cantilever center span. It opened in 1966 as an element of Portland's Interstate transportation system and was the city's first double-deck highway bridge built exclusively for vehicular traffic.        It was named for Philip Marquam, a 19th century transportation advocate, but its strictly functional appearance engendered, ironically, an outcry for public participation in future bridge designs—and periodic discussions of the merits of its removal.
