Maintenance work on the Maple-Oregon Street Bridge in Sturgeon Bay has been delayed again.  Friday, the Wisconsin Department of Transportation announced another delay due to colder temperatures forecasted for next week.  The low temperatures would inhibit the ability to apply a polymer overlay to the bridge surface.   The future work on the bridge will include concrete deck repairs, laying a polymer overlay to protect their work, marking the pavement, and rebalancing the lift spans during the month-plus long project.  Repairs on the Maple-Oregon Street Bridge, which was to begin Monday and continue through May 15, will now be rescheduled for a later date.  The full project was originally expected to be finished by June 19.
