Two bridges in Greenwich were among 12 in the state listed in "critical" condition by state safety inspectors as of August 2007.
The Riversville Road bridge, built in the 1950s, now has a weight limit of 3 tons, but as of August 5, 2007, the bridge had not been inspected in over two years (in March 2005), according to state records obtained by the Hartford Courant, although a state official said the bridge was inspected in August 2005 and would be inspected again in August 2007.
In the March 2005 inspection, the bridge's above-ground structure was deemed to be in critical condition, with other components in poor condition.
The Bailiwick Road bridge in town was closed in April 2007 and remained closed as of August 2007 due to storm damage.
The ratings for the two bridges were worse than the Interstate 35W bridge in Minneapolis, which collapsed during rush hour on August 1, 2007.
