Merchant Street Bridge

It appears the bridge has a stone facing, but the Historic Bridge Inventory folks felt the stone facing dated to the 1919 construction of a stone arch, and they could not find any evidence that the original stone arch remained. The inventory comments follow:

The bridge carries a two-lane, brick-paved street and sidewalks over a creek on the Ambridge-Leetsdale line. The setting does not have historic district potential. There are modern buildings at the NW quadrant in Leetsdale, and the 1916 brick building beyond the NE quadrant has altered storefronts. There are highly altered buildings in Ambridge and a 1920s electrical substation beyond the SE quadrant. The area does not have consistency or cohesiveness.

The well-proportioned, one span, reinforced concrete arch bridge built in 1919 and reportedly incorporating an 1827 stone arch (not visible at all) is finished with rusticated ashlar spandrel walls and wingwalls. The arch ring is accented with vermiculated ring stones. The roadway is inclined across, so the paneled stone parapets are stepped. The bridge exhibits the same fine masonry as the earlier stone arch bridges built by the county. It is an example of a bridge type and design that are common in the county, and neither the bridge nor its setting are historically or technologically significant.

I fish under this bridge often and know it well. I was surprised to hear it categorized as "concrete". It appears to be built from cut stone blocks. I can send you some pictures of it, if you like.
