Portions of 1st Avenue and Jefferson Street in Sturgeon Bay will be formally closed on Tuesday at 7AM. 1st Avenue will be closed from just north of Kentucky Street to Iowa Street/3rd Avenue, and Jefferson Street will be closed westerly of the alley that serves 3rd Avenue. The street closures were approved by the city council in January as a means of assisting Fincantieri Bay Shipbuilding Company’s expansion into the vacant Palmer Johnson yacht facilities. As part of the street closure agreement, Fincantieri is meeting the 11 conditions placed on them for the city to close the streets. Those conditions include paying for public street/traffic improvements and certain improvements to their existing shipyard. Mayor Thad Birmingham said the street closures will mean residents and visitors will have to plan their routes accordingly.
