Lauren Rogers Museum of Art officials say a $5 million capital campaign will add 5,400 square feet to the Laurel museum.

The campaign, in its silent phase for the past 15 months, has already raised $4.25 million.

The museum will use $3.5 million for new gallery space, a new storage vault and an expanded loading dock.

The remaining $1.5 million will be directed toward the museum’s endowment.

Officials expect to break ground on the new space in January, with a grand opening planned for May 2013 – in time for the museum’s 90th anniversary.
