: Bridge, Tunnel Safety Measures Enhanced"> "Were able to get then information either to an individual or to an agency, and we were able to get it to folks accurately and timely, and it was invisible as far as the [international] border was concerned," he said When it comes to other new technology on bridges and tunnels, though, officials are guarded about offering details with the threat of terrorist attacks still looming."Pre Sept. 11 we might have thought about it, but now absolutely we wont talk about it," he said. In San Francisco, the landmark Golden Gate Bridge has faced heightened security since last years terrorists attacks on the east coast. That included two "super-heightened" alerts, one for three days in mid-August after word of a terrorist threat to crash a plane into the bridge and earlier in July after Spanish authorities found a videotape of potential terrorist target believed to be from al-Qaida members that included footage of the Golden Gate bridge. The Golden Gate Bridge Highway District has upgraded and expanded its system of surveillance cameras on the bridge, said district spokeswoman Mary Currie. But she declined to offer any more details on technology steps taken since Sept. 11. Bridges across the state of California, as in other states, have heightened physical security. The California Highway Patrol has stepped up its patrols of bridges such as the Golden Gate and the San Francisco-Oakland Bay Bridge, said Sgt. Wayne Ziese, public information officer for the CHPs Bay Area command, in Vallejo, Calif. Officers also have begun using handheld thermal imaging devices, or night vision, to allow officers to see better. The CHP also has budgeted for more aircraft for its patrols, Ziese said. "Obviously the real threat from terrorists has been well documented since 9/11 and the responsibility has been put on us to make safe to the best of our abilities these key transportation links," he said.
