It's not a common design for the late '50s. Perhaps the date is why it wasn't on the site. I also wonder if '57 is a rehab rather than a build. Nice to see a well cared for concrete arch.
I was worried I was adding a duplicate bridge here, I am not sure why this still extant large concrete arch bridge was not listed here... an unfortunate development as I drove over this bridge on my way to the Chagrin Falls Bridge. Due to the rehab it does not look historic from the road.
Clark,
I agree it might be that when James put together the website he only imported pre-1950 concrete arch bridges.
I pulled up the Historic Bridge Inventory and it seems the reason an arch was built here in the 1950s was because of its park setting. Here is the info from the inventory:
The South Chagrin Reservation bridge placed in 1957 and was designed by Osborn Engineering of Cleveland, who did other bridges for the Metropolitan Park Board in the 1950s and 1960s. The open spandrel arch bridge type was used because of the setting in the reservation. The bridge has no distinctive or innovative details, and it is traditional in its design and aesthetics. While handsome and representative example of its monumental bridge type, the bridge is a late example of a technology that had been used in Ohio and throughout the nation in similar settings since about 1910. There are numerous earlier examples including the 1909 Barrett Road railroad bridge in Berea and the 1925 Hilliard Road Bridge, both in Cuyahoga County, and the 1917 Victory Parkway Bridge at Cincinnati, as well as many of them have been determined to be select. This bridge is not historically or technologically significant. Osborn Engineering Company was the earliest engineering firm in Cleveland, and in addition to their many bridges and buildings in Cleveland, they are nationally known for stadiums.
