The Fairfax County Park Authority's newest facility, Providence Recreation Center, was dedicated Sunday in memory of the late Dr. Edwin Bancroft Henderson, in recognition of his services to the community and the nation as an educator, pioneer in black athletics and civil rights activist.

Included in the 38,000-square-foot center at 7525 Marc Dr., Falls Church, are a 25-yard by 25-meter indoor swimming pool with two one-meter diving boards, an outdoor sun deck, saunas, locker and shower rooms, an exercise room, four racquetball/handball courts, a video game room, a dance room and a snack bar.

The new facility is completely accessible to the handicapped, according to Park Authority Providence District representative John Mastenbrook. "The rampways, elevator, parking lot, telephones, drinking fountains, showers, toilets, wash fountains and locker rooms all have been designed to provide accessibility to the elderly and physically disabled," he said.

The $3.1 million center was designed by Hughes Group Architects of Reston, and the construction contract was awarded to Gardiner and Gardiner of Crofton, Md. Funds for the center were approved by county voters in the 1977 park bond referendum. Operating and maintenance expenses are to be covered by fees generated at the center.

The center is open daily from 6 a.m. to 10 p.m., and the pool is open Monday through Friday from 8 a.m. to 10 p.m. and Saturday and Sunday from a.m. to 10 p.m.

General admission for county and noncounty residents is $2 for adults, $1 for senior citizens, and $1.50 for children under 16. For more information, call the center at 698-1350.
