The Marquam Bridge is a double-deck, steel-truss cantilever bridge that

the lower deck carries southbound traffic.


The bridge was designed and built by the
Oregon Department of
Transportation
 at a cost of $14 million. The lower southbound deck
was opened on October 4, 1966, and the upper northbound deck on
October 18, 1966. The Marquam was
the first Portland bridge to
undergo a
seismic retrofit in 1995.
