PART II: Main Thoroughfares|
Pittsburgh: Main Thoroughfares and The Down Town District
Frederick Law Olmsted report to The Pittsburgh Civic Commission, 1910
the Castle Shannon railroad bridge a branch connection should be run west across the valley to Boggs Avenue, about at Minsinger Street, thus connecting the new tunnel with Boggs and Southern Avenues leading to Mt. Washington.
73. (a) Beechview Thoroughfare. -- The higher lands to the south, upon which most of the future development will take place, can best be reached by a street around the west end of the Beltzhoover ridge at, or slightly above, the level of the Castle Shannon railroad, about the location of the present Boggstown Avenue. From a point two or three hundred feet east of Sylvania Street a sloping viaduct should be run southwest up over the street railway bridge and the West Side Belt tracks to the nose of the opposite hill. From here a new street should be run west climbing gradually along the north slope of the hill to the high land at the northern end of Beechview. An extension of this line should then be made from Crane Street and Center Avenue southerly along the west side of the Beechview ridge joining Seventh Avenue just south of South Sharon Avenue. Beechview and the West Broadway thoroughfare, running south along the ridge, can thus be reached on a gradient under 4 per cent instead of 6-1/2 or 7 per cent along the present street car right-of-way, or considerably more than that on the present streets. The viaduct from Southern Avenue to Price's Hill, proposed in the recent bond issue program, has been studied with some care, but the steep gradients it would require -- 6 per cent or over -- to reach the hilltop land have led to its abandonment in favor of the plan just proposed.
(b) West Broadway Extension. -- West Broadway should be extended along the present street car route from Snyder Street south to the junction of the Banksville and West Liberty Roads.
(c) Lang Avenue Connection. -- Starting again from the southerly end of the above proposed viaduct over Sawmill Run, a street should be built running south over the West Liberty road and striking the opposite hillside at or just above Lang Avenue. Southwest from here, nearly to Summerhill Street, Lang Avenue should be shifted slightly down the hillside to reduce its gradient from about 12 to 4 or 5 per cent.
(d). Sawmill Run Hillside Thoroughfare. -- Returning now to the northerly end of the proposed viaduct over Sawmill Run, the thoroughfare from Washington Avenue should be extended south
