Every year, participants in Canstruction, a charity food drive, create sculptures out of canned goods. This year’s theme was transportation, which led to replicas of the Metro map, Washington Dulles International airport, and a Car2Go.

Sponsored by the Washington Architectural Foundation, Canstruction’s goal is to raise awareness about hunger in DC. According to the event’s website, Canstruction teams donated nearly 56,000 pounds of food and $8,000 in cash in 2014— the equivalent of about 42,000 meals.

The photo above is of the OutSMARTing hunger Metro map, which the Young Constructors Forum (YCF) of Associated General Contractors of Metro DC built with 2,800 cans.

Even the popular car sharing service Car2Go was featured, with a Can2Go sculpture by Barnes Vanze Architects.

All of the 68,313 cans used in the 24 sculptures were donated to the Capital Area Food Bank on Black Friday, says the Washington Architectural Foundation.
