Excerpt from Exhibit of the Office of Public Roads: Alaska-Yukon-Pacific Exposition Visitors will probably decide that the most striking feature of the display is the miniature model of a section of Rock Creek Park the most beautiful of the many breathing spots in the District of Columbia. In this handsome miniature is shown not only some of Rock Creek Park's most picturesque landscape features but also some of the best examples obtainable of scientific road construction. The model includes the famous Bowlder Bridge, the Pebble Bridge, and one other, with Rock Creek passing beneath them and winding in and out among the hills. Picturesque, and yet practical, as is this handsome centerpiece of the exhibit, it will not attract as much attention from scientific road builders as will the miniature sections illustrating every type of road now 111 use. Among the types thus illustrated, built to exact scale, are macadam, bituminous macadam, tarred macadam, Telford, slag asphalt, slag tar, oiled macadam, oiled earth, sand clay, burnt clay, and dragged earth.
