PART II. ARCHITECTURAL AND STRUCTURAL INFORMATION

The northern approach spans of the West End-North Side Bridge carry L.R. 76, Spur 1, from Route 51 on the south to the Ohio River Boulevard on the north. The bridge crosses the Ohio River approximately one mile below the "Point," the confluence of the Monongahela and Allegheny rivers. The four northern approach spans are Warren half-through or pony trusses and were constructed in 1931-1932.

Examination of the original design drawings and field inspection of the four northern pony truss bridges reveal that they are virtually identical except in length and in the number of panels. Span 8, nearest Western Avenue, and span 5, nearest the masonry pier (spans 6 and 7) measures 152.75 feet in length. Table 1 presents the major measurements of the different trusses components. The northernmost pony truss (span 8) is typical of the four and has been selected for detailed description and photographic documentation. An extensive series of the original design drawings has been photographically reproduced (8x10-inch format) for the HAER recordation package and xerographically reproduced for the bound report. A second series of 4x5-inch negatives and contact photographs of members and components of span 8 is included in the HAER documentation; xerographic copies are included in the bound report.
