DAVENPORT, Iowa (AP) — Davenport officials have closed a bridge that carries thousands of vehicles daily after finding the span’s surface showed “widespread deterioration.” The Quad-City Times reports that city officials announced Wednesday that Elm Street bridge would be closed to vehicles and pedestrians. Assistant City Administrator Brandon Wright says city workers first discovered holes in the bridge’s deck on Monday. He says they immediately closed off the bridge, though some people continued to use the span.

Wright says an inspector told the city midweek that the bridge should remain off limits. He says the city is waiting for a final inspection report and that it’s unclear when the bridge will reopen. Wright says the city received an estimate last year that says replacing the bridge would cost about $3.4 million.
