Engineers: Lucas Oil Stadium roof working properly

A state agency says Indianapolis Colts fans can rest assured: Engineers have verified that the Lucas Oil Stadium retractable roof is working properly.

The news comes nearly a month after a structural bolt fell in the middle of an Indianapolis Colts preseason game and injured three fans.

After several tests, engineers have certified that the roof is now fully operable, according to a written statement from the Indiana State Convention and Building Authority on Friday morning.

Inspectors found that the bolt that fell and seven others in two locations were not tightened properly, authority director John Klipsch said in the statement. To fix it, engineers replaced the “improperly installed” bolts with redesigned washers, longer bolts and double nuts.

Klipsch said engineers have monitored the repairs and have observed the successful opening and closing of the roof.

The roof has remained closed for all games since the incident.
