A blank canvas awaits artists next to a busy Metro entrance. The National Landing Business Improvement District is looking for designs for a Crystal City Metro station project: creating a mural on a blank retaining wall to greet travelers. The winner will have a space about 115 feet long and 20 feet high for their artwork. The art project comes amid an overhaul of the station plaza with new seating, a more open layout and other changes to the landscape and area planned for this year, according to the BID. Other imminent changes slated for the area include a second entrance for the Metro station closer to Crystal Drive as well as the ongoing construction of Amazon’s HQ2 several blocks away.
