Construction on the nearly 2,000-foot-long (609-meter) bridge began in late January 2005 and the bridge spans the Black Canyon (south of the Hoover Dam) and rises nearly 900-feet above the Colorado River. As a consequence of the heightened security following the September 11, 2001 attacks, truck traffic over the Hoover Dam had been banned, in an effort to safeguard the dam from hazardous spills or explosions. However this has not eliminated the threat of a possible attack on the dam, as regular traffic still passes over it and the new bypass bridge will replace the dangerous dam roadway, and reduce the possibility of an attack or accident.

In the US, nuclear operators have focused on improving safety and efficiency at existing plants. There have been no notable US accidents since 1979 at Three Mile Island and the US reactor fleet has produced at about 90 percent of licensed capacity since 2001, up from efficiency figures of the early 1980s. Nuclear plants today produce about 20 percent of the electricity used in the US. Dozens of electrical companys are seeking licenses for as many as 31 new nuclear power reactors in the US.FILE - In this Oct. 15, 2015, file photo, vehicles pass a highway construction site on eastbound Interstate 80 in Sacramento, Calif.
