Prior to the renovations of Roosevelt Dam in 1989, traffic had to be diverted off the top of the dam. The Roosevelt Lake Bridge was constructed to relocate Highway 188. The blue painted steel bridge spans 1,080 feet across the reservoir. It is the longest two-lane, single-span steel arch bridge in North America. In November of 1995, it was designated as one of the top twelve bridges in the United States along side the Golden Gate Bridge and Brooklyn Bridge.
