The referenced HAER record is PA-5, and it says to access PA-3. But I could not find PA-3. Fortunately, pghbridges did find it. Unfortunately, I could not find a link to the source. Fortunately, pghbridges copied the content. Search for ": 1877" in pghbridges. It has the history and an extensive description of the 1877 bridge.
The 1877 bridge was removed soon after it was replaced by the 1927 bridge. The 1927 bridge was replaced by the Fort Pitt Bridge in 1959, but it was not removed until 1970.

The Point Bridge, Pittsburgh, Pa.
Evidently someone enhanced the above LoC photo. This source has some additional photos.
The original Point Bridge in 1900.
Engineering News – July 8, 1876 reported,“The center span is 800 feet center to center of towers, and the side spans are 145 each in the clear. The height of the towers above low water is 180 feet, and the deflection of the chain is 88 feet. The roadway is 20 feet wide with double tramways and one track for a narrow gauge railway; outside of the roadway are sidewalks six feet wide each. The piers and anchorages are founded upon timber platforms sunk to a gravel bed. The masonry is of the best quality Baden sandstone. The superstructure will be the first example of a stiffened chain suspension bridge of long span and will differ considerably from others in existence.”
This photo clearly shows the amount of redundancy in the tie-bar chains.

While researching the Point Bridges that were in Pittsburgh, I came across this Detroit Publishing Co. photo, circa 1900-15. It shows the importance that riverboats, railroads and street cars once had in that area.
Dennis DeBruler: Robert Swenson So they are waiting for the wet season so that there is enough water in the Ohio River to provide the needed draft. I remembered that this was well before the 9-foot channel project was built. But I never realized how they queued up waiting for the rains to come.

HAER describes this as "a cantilever, arch-truss" bridge.

The two Point Bridges side-by-side in 1927. The old suspension bridge would soon be dismantled.
