The construction contract for the Colorado River Bridge, was awarded to the joint venture partnership of Obayashi Corporation and PSM Construction USA, Inc., in October of 2004 for US$ 114 million. Construction began in early 2005 and is expected to be completed in 2010. When completed, the 2000 ft-long (610 m) Colorado River Bridge will span the Black Canyon (about 1500 ft/457 m south of the Hoover Dam), connecting the Arizona and Nevada Approach highways nearly 900 ft (274 m) above the Colorado River.
