DEL MAR, Calif. -- The Del Mar Arena at the Del Mar Fairgrounds is scheduled to reopen Thursday following a $15 million renovation that included installation of a 76,267-square-foot roof.

Officials will mark the completion of the project with a ribbon-cutting ceremony to coincide with the start of the three-week Del Mar National Horse Show, which will be held in the arena.

The renovation project, which began last September, was funded through revenues generated at the Del Mar Fairgrounds.

The new roof, built by Turner Construction Co., will allow the arena to be used year-round for concerts, trade and consumer shows and sporting events, according to fairground officials.
