Avenue but along the hillside above the railroad tracks. This thoroughfare would leave Forbes Street at the bend about 1200 feet east of Brady Street, cross the little valley (which should be filled north of the new street) and extend eastward, crossing Bates Run on a viaduct, and using, where possible, parts of Lawn and Frazier Streets, to the mouth of Four Mile Run. Thence, by another viaduct, it would connect with Sylvan Avenue, on the north side of the valley, and follow this street widened to Hazelwood Avenue; by another viaduct it would cross the Flowers Avenue valley to Glenwood Avenue and follow the latter widened and partially regraded to Mansion Street. There it would bend to the northeast, cut through the plateau land to the next ravine, cross this on a viaduct and, bending southward again, descend around the nose of the hill to the Glenwood bridge. So easy a gradient can be obtained on this new street that it may reasonably be expected to carry nearly all the through traffic. With proper connections (the most important of of which are described below), it will also take most of the travel to and from the residential districts Iying above it to the northeast.

Diagram No. 7. Monongahela hillside thoroughfare -- a typical section

The location of this street, high on the hillside above the Monongahela River, presents unusual opportunities incidental to serving its primary purpose as a main thoroughfare. With an ample roadway for all kinds of traffic, with trees for shade and decoration, with a broad promenade overlooking the river and the hills to the south, it would furnish rare and much-needed facilities for recreation; and, further, it would have a distinctive character most appropriate to the rugged topography of the Pittsburgh District. (Diagram No. 7.)
