Opening day for the Lions at the Silverdome was on October 6, 1975. The Silverdome became the largest stadium in the NFL with a capacity of 80,311. Three tiers of blue seats circled the entire Astroturf playing field. The roof at the Silverdome consisted of Teflon-coated fiberglass panels. In 1985 after a heavy snowstorm the roof was structurally damaged. However over the next several months a new canvas and steel-girder reinforced roof was added to prevent the problem from occurring again. The Silverdome had several amenities that included 93 executive suites and a club restaurant. Other than hosting football games, the Silverdome hosted many other events including tractor pulls, soccer and basketball games, and concerts. The first Super Bowl played in a northern city, Super Bowl XVI between the Cincinnati Bengals and San Francisco 49ers, was played at the Silverdome. In the mid 1990s, the Lions became dissatisfied with the Silverdome. By 1997, bonds were passed allowing construction of a new domed stadium in downtown Detroit. The Lions played their final game at the Silverdome on January 6, 2002. The team moved into Ford Field in August 2002. In July 2008 the Silverdome was sold to a local investor and the site is schedule to become a hotel and conference center.
