LOS ANGELES, Aug. 3 (Xinhua) -- Cities across the United States are scrambling to double-check safety of bridges after the collapse of a Minneapolis bridge into the Mississippi River, killing at least five people and leaving about 100 injured.

In Los Angeles, city council members Friday introduced a motion asking the Bureau of Engineering and the Public Works Department to provide an update on the city's bridge-renovation program.

Los Angeles County Supervisor Mike Antonovich also planned to ask his colleagues next week to have county road engineers "redouble their efforts" to look at area bridges in light of Wednesday's tragedy in Minneapolis.

"We are confident with our bridges, but we're asking them to take one more look, to be vigilant in their inspection and maintaining practices," said a spokesman for Antonovich.

Los Angeles officials said there are two bridges in the city similar in design to the Minnesota bridge, and both are scheduled for replacement.

Each of the 500 bridges in Los Angeles is inspected every two years to assess safety, ability to accommodate traffic and structural integrity, according to the city's Board of Public Works President Cynthia Ruiz.

Ruiz said the city is responsible for inspecting 66 of the bridges, with California state transportation agency Caltrans responsible for the remaining 434.

Caltrans officials earlier on Thursday began emergency structural inspections of 69 bridges across the state, many of them among the nearly 3,000 bridges that have been classified as "structurally deficient," the same rating held by the collapsed Minneapolis bridge.

Engineering experts warned that with many of California's bridges 40 to 70 years old, it is likely the state will suffer failures of its own at some point.
