Long Description:
The Gothic-tower St.
Johns Bridge, completed in 1931, is the most spectacular bridge in
the city of Portland. The bridge was designed by Holton Robinson
and internationally renowned bridge architect David Steinman. It
was the longest rope-strand suspension bridge in the world at the
time of its construction.
The bridge is a
two-tower cable steel suspension, steel deck half-through truss. It
spans the Willamette River, connecting the St. Johns area of North
Portland with the industrial area of Northwest Portland—US 30
bypass.
The bridge is 2,067 feet
long. The bridge has two 408-feet-high Gothic towers with a 1,207
foot main (center) span, a total length of 2,067 feet, and a
navigational clearance of 205-feet at low water. It was painted a
pale green color to blend into the landscape. The bridge was
renovated from 2003 to 2005 including repainting
it.
The bridge is named for
the community at its east end, which was originally named in honor
of settler James John. James John, the founder of St. Johns,
Oregon, was born in 1809 in Ohio. In 1846 he built himself a brick
building at the edge of the river on what was once an Indian
camping ground. He filed for a Donation Land Grant of 320 acres in
1850. In 1852, he operated a general merchandise store as well as
started a ferry across the river near this place with just one
rowboat.
The bridge has been
designated a historical landmark. It has four benchmarks: RD3632,
RD3634, RD3654 and RD3627. The coordinates are the location of the
northwest tower. There is a pull off on the Oregon side (US-30)
where it is possible to get a great photo of the entire
bridge.
