Built in the first decade of the 20th century, a car barn was built on Wisconsin Avenue on the eastern side of the square. It is the site of transportation activities that contributed significantly to the development of the District of Columbia. It is associated with patterns of growth and change that resulted in significant development of the residential areas along the routes served by the buses.
The Western Bus Garage was designed by the architect Arthur Heaton. He was a lover of colonial architecture and made frequent trips to Williamsburg, Charlottesville, and Fredricksburg for fresh ideas and inspiration. He was particularly interested in the slight variations in moldings, bricks and details of old buildings. The Western Bus Garage reflects his interest in brickwork. The main 44th Street facade is given a monumental treatment in tapestry brick and limestone, using modernistic motifs of the 1930s Art Deco period.
