| HAER OHIO,31-LOCK,1--4 4. SIDE VIEW OF BRIDGE, LOOKING SOUTHWEST, SHOWING ARCHES, CANTILEVERED WALKWAY, DECK BEAMS AND STREAMBED - Benson Street Concrete Bowstring Bridge, Spanning Mill Creek at Benson Street, Lockland, Hamilton County, OH |
"Significance: The Benson Street Concrete Bowstring Bridge is important because it may be the first example of a through bridge of this design to be built in America. It was constructed in 1909 (not 1920 as was once thought) and therefore predates James Barney Marsh's influential patent for a concrete bowstring by two years. Although designed by E.A. Gast, It actually may have inspired Marsh at the time when he was working on bis own designs. Concrete bowstring bridges were not generally popular in America until about 1920. The bridge is listed as a "reserve pool bridge" in the Ohio Department of Transportation's Ohio Historic Bridge Inventory Evaluation and Preservation Plan." [HAER_data]

Evidentially the falsework was needed until after the concrete in the arch cured.

Bridges & Tunnels posted two photos with the comment:
This unassuming concrete pony arch bridge, often called a rainbow arch, was the first of its kind in Ohio—and possibly in the United States. Designed by E. A. Gast and completed in 1910 between Reading and Lockland, it preceded James Barney Marsh’s 1911 patent for a comparable design.🔗 Learn more about this bridge's history: https://bridgestunnels.com/location/benson-street-bridge/
