The long-delayed and scaled-down expansion of Arlington County’s Long Bridge Park aquatics center and the related 10.5-acre park will go out for design bids this summer, county officials said, to cost no more than $67 million.

The design-build process is intended to provide a 73,000-square-foot facility with two pools and a fitness center. Options for the winning building would include advanced energy efficiency, a therapy pool, a 10-meter dive tower and more spectator seats. Bidders, once qualified by the county, would submit their designs to public scrutiny and would be subject to County Board approval. Construction is expected to begin in late 2018.

The construction was put on hold in 2014 after bids significantly exceeded the $79 million projected cost and after the cost of the facility became an issue in County Board elections that year.
