A second lawsuit has been filed by the River Fields conservation group over the closing of the Harrods Creek Bridge.The group has already sued to stop the city from rebuilding and widening the one lane span. Now it has filed a second suit, claiming the Coast Guard did not properly review the city's plans for the project.The bridge was deemed unsafe by the state and closed last year. River Fields' Attorney Don Cox says the group has done its own study on the bridge and says the construction project is unnecessary."Our engineer has indicated the bridge is as sound today as it was the day it was built. Some work needs to be done on the railings to bring them up to snuff and the bridge itself needs to be repaved," he says.The city has already awarded a $2.3 million contract to rebuild and widen the bridge. A spokesperson for the mayor's office says the project will continue.
