A proposed skyscraper in Tysons Corner will be 435 feet tall, making it the tallest in the DC region, and first to breach the 400 foot threshold. The building is proposed as part of the SAIC redevelopment, adjacent to the Silver Line’s Greensboro Metro station.

Traditionally, the tallest skyscrapers in the region have been in Rosslyn. But Rosslyn is in the flight path to National Airport, so buildings there can’t rise higher than 400 feet. A bevy of development projects in Rosslyn, Alexandria, Tysons, and North Bethesda are in the 300-400 foot range, but this is the first serious proposal to crack 400 feet.

Outside the DC region, Maryland’s tallest building is 528 feet, and Virginia’s is 508 feet. Richmond’s is 449 feet.
