615-foot Tysons skyscraper proposal would be the tallest in all of Virginia, Maryland, or DC...The tower, if built, will be 48-stories and 615-feet tall, directly adjacent to Spring Hill Metro station. It would be mainly condos, with some floors reserved for a hotel, and retail along the sidewalk....According to developer Dan Clemente, funding is lined up and ready to go as soon as Fairfax grants zoning approval. That will probably take 12-18 months.
