Beginning Monday, April 15, 2013, the City of Port Huron in cooperation with the Downtown Development Authority will commence with the abandonment of the Sperry’s basement area under the sidewalk along Grand River and Superior Mall. West bound Grand River from Huron Avenue to Superior Mall will be closed to through traffic. Superior Mall and east bound traffic of Grand River will remain open but may have intermittent delays for certain work activities. Access to businesses will be maintained. This work will be ongoing through approximately mid June 2013.
