Demolition of the parking deck adjacent to the St. Marys City Utility Office on East Spring Street began earlier this week. The 40-year-old structure was showing wear and tear and had been closed for more than a year. The project, which also butts up to the newly uncovered Miami & Erie Canal lock 13, is expected to be completed sometime this fall. The demolition is being done by VTF Excavation of Celina for about $13,000.
