Representatives from the state Department of Transportation have met with Ridgefield residents to discuss the Portland Avenue bridge replacement project.  Plans for the project include adding a traffic light on Route 7, two through lanes and a left-turn lane for southbound traffic.  The bridge itself will have one lane in to the train station from Route 7 and two lanes out.  The DOT says at least one of the two bridges that connect the Branchville Train Station to Route 7 should be open during the work.  The Depot Road bridge at the north end of the station will have to be repaired and reopened before the Portland Avenue bridge project begins.  The Depot Road bridge was closed earlier this month due to structural deficiencies.
