Crystal Bridges Museum of American Art in Bentonville announced Thursday that it won't charge admission for patrons to see what's promised to be one of the best art collections in the nation.

The museum will replace that revenue with a $20 million grant from Bentonville-based Wal-Mart Stores Inc., which will provide the money over five years. The museum had planned to charge $10 per person.

The museum is funded by the fortune of Wal-Mart heiress Alice Walton and has been outbidding top museums for acquisitions that will go on display to the public on Nov. 11.

Wal-Mart President and Chief Executive Officer Mike Duke said the world's largest retailer made the donation so its workers and the rest of the community could regularly enjoy the museum.

Crystal Bridges Executive Director Don Bacigalupi said the gift enables the museum to "become a daily resource in our community."

"One of the greatest challenges for museums today is finding ways to remove barriers to community participation, including admission charges," Bacigalupi said.

The museum and grounds, designed by architect Moshe Safdie, are expected to attract visitors from around the world.

Arkansas Parks and Tourism Department Director Joe David Rice said the free admission will help generate tourism from state residents and the larger surrounding area. Bentonville is in the far northwest corner of Arkansas, and Rice said free admission will help draw repeat visits from people on day trips from Tulsa, Okla., Springfield, Mo., southeast Kansas and other communities.

"We're trying to figure out exactly how big this is going to be up there," Rice said.

The Clinton Presidential Center in Little Rock turned the city's formerly desolate downtown into a thriving area with new hotels and office buildings, loft apartments, galleries, nightclubs and museums.
