The Burnside bridge takes its name from Burnside Street, which was named for Daniel W. Burnside (1825-1887), a Portland flour merchant, and a partner in the firm Snow, Burnside & Savier, located on S.W. 4th Ave.

The original Burnside Bridge was completed in 1894. Two of its spans were relocated over the Sandy and Bull Run rivers, and some of its girders were used in the approaches of the Sellwood Bridge.

This Burnside Bridge was the eleventh of twelve movable bridges built in Portland's harbor during the twentieth century; only the Morrison Bridge is newer. It was originally designed by Ira G. Hedrick and Robert Kremers of Portland. The opening mechanism is the patent of Joseph Strauss (1870-1938), whose Golden Gate Suspension Bridge would open 11 years after the Burnside.

The Burnside Bridge was Portland's only bridge designed with an architect's input, resulting in its Italian Renaissance towers. In the 1920s, fiscal shenanigans resulted in the indictment of public officials and engineers responsible for erecting three bridges across the Willamette. Gustav Lindenthal, consulting engineer, was called from New York City to save the day. One of the most respected bridge engineers in the world, Lindenthal redesigned the Ross Island and Sellwood bridges, and finished the Burnside Bridge. The three were the largest construction projects on the West Coast at the time and came in on budget. They opened the east side to vast expansion of residential neighborhoods.

The entire bridge is 2,308 feet long, with a 252 foot center span and two 268-foot steel deck truss spans. The bridge is 86 feet wide and originally featured six traffic lanes. One lane was removed in 1995 to make room for two bicycle lanes.  Its concrete deck makes it one of the heaviest bascule bridges in the United States, and the counterweights in the piers weigh 1,700 tons.
