Unguarded border bridges could be route into US

On each side of a towering West Texas stretch of the $2.4 billion border fence designed to block people from illegally entering the country, there are two metal footbridges, clear paths into the United States from Mexico. The footpaths that could easily guide illegal immigrants and smugglers across the Rio Grande without getting wet seem to be there because of what amounts to federal linguistics. While just about anyone would call them bridges, the U.S.-Mexico group that owns them calls them something else. "Technically speaking it's not a bridge, it's a grade control structure," said Sally Spener, spokeswoman for the International Boundary and Water Commission, which maintains the integrity of the 1,200-mile river border between the U.S. and Mexico. The structures under the spans help prevent the river -- and therefore the international border -- from shifting. Whatever they're called, there are fresh sneaker tracks on the structures -- indicating they're being used as passages into the country. In a border tour with the Hudspeth County Sheriff's Office in March, Associated Press journalists happened upon the bridge moments after a man with a bicycle used the bridge to cross the river from Mexico. The border crosser, who told authorities he was only trying to fish from the north side of the river, was promptly arrested. "If he can do it, so can drug cartels with loads of narcotics of any kind," Hudspeth County Sheriff's Lt. Robert Wilson said. "Even a terrorist could pass here with weapons of mass destruction and be in the United States and up on the interstate and gone in a short time." It's unclear how often the bridge is used, but it's common to see people on the Mexican side lingering around the crossing or others playing in the river in the area...more
