Hoover Dam Closed to Commercial Vehicles
Hoover Dam and surrounding highways have been closed indefinitely to commercial vehicle traffic, according to a report issued by the Federal Motor Carrier Safety Administration (FMCSA). The agency said in an e-mail that FBI sources indicated the action was precautionary, and not in response to any direct threat.
According to a report on the Las Vegas Review Journal web site, Hoover Dam is open to passenger cars only. The visitors center and parking areas remain closed, the web site said.
US Route 93 runs over Hoover Dam, which is on the Nevada-Arizona border. It is 30 miles southeast of Las Vegas NV.
