The Monroe Street Bridge is a deck arch bridge in the northwestern United States that spans the Spokane River in Spokane, Washington. It was built 113 years ago in 1911 by the city of Spokane, and was designed by city engineer John Chester Ralston, assisted in construction supervision by Morton McCarthy (and by assistant engineers J. F. Greene and P.F. Kennedy) with ornamentation provided by the firm of Kirtland Kelsey Cutter and Karl G. Malmgren as part of Cutter & Malmgren.

At completion, it was the largest concrete arch bridge in the U.S. and the third longest in the world. After more than ninety years of service, it was closed in January 2003 for restoration and reopened in September 2005.

History

MonroeStreetBridgea
The third bridge under construction

The current bridge of 1911 is the third in this location. The first, a rather rickety wooden structure, was built in 1889. It was closed for a time due to arguments in the city over rights of passage and ownership, and burned down in 1905.

The design of the third bridge was largely copied from the Rocky River Bridge in Cleveland, Ohio, but was built one foot (0.3 m) longer to make it the largest concrete arch in the U.S. at the time. In turn, the Rocky River Bridge was modeled after the Walnut Lane Bridge in Philadelphia, which was modeled after the Adolphe Bridge in Luxembourg.

The Monroe Street bridge was designed with ornamental features such as bison skulls, covered pavilions, and a chain-link railing motif. The bison skull was an inspiration of P. C. Shine, who had found it in Alberta at Drumheller in the early 1900s. Located just west of the Falls, the bridge runs due north-south and opened on November 23, 1911.

20th century modernization

The bridge underwent changes in 1925 and in 1934, and submitted to the modernization of Spokane. The pavilion lamps were converted to electric lighting in 1925, and the electric car railways were removed from the bridge in 1934. Approaching 65 years of service in 1976, the bridge was listed on the National Register of Historic Places.

21st century restoration

By the 1990s, the bridge had deteriorated to the point where rebuilding it was necessary. In January 7, 2003 it was dismantled down to the central arch, and rebuilt faithfully to its original appearance. The bridge was reopened in 2005 on September 17, with new railings and concrete separating the walkways from the road.
