The Ross Island Bridge, which opened in 1926, carries over 55,000 vehicles per day and is the only bridge connecting Portland's South Waterfront district to the Southeast side. The 3,700-foot-long cantilever deck truss bridge was designed to accommodate the city's growing automobile traffic and was not designed to raise for river traffic. It was originally painted black but underwent a "phthalo blue" makeover in 1965. The bridge also features large pipes that move water from the Bull Run reservoir system to Portland's west side.
