The new promenade on Sturgeon Bay’s west side waterfront is expected to open before Independence Day after some slight delays.  Contracted construction crews mounted benches along the promenade’s concrete sidewalks this week and will be placing topsoil and completing other final details in the next week.   City of Sturgeon Bay Administrator Josh Van Lieshout says the nearly 1.4 million dollar project is slightly behind the originally scheduled opening of June 15.  He says high water conditions contributed to delays due to the abandonment and relocating of storm sewers.  The Sturgeon Bay Submarine Cable Replacement Project by American Transmission Company also lingered long into the spring.  The waterfront promenade project will keep the tug boats belonging to Sarter Marine Towing, although they will be positioned slightly closer to the Oregon Street Bridge.
