Higginsport Bridge

From Higginsport side of creek
Road appears to be used only by campers. The bridge itself seems to be solid enough for light-duty use, but something would need to be done quickly.

Description
This bridge contains a a-frame lattice portal bracing with a cast iron decorative detail at the base of the a-frame. This is a detail associated with the Smith Bridge Company, and this bridge is thus associated with that company.The single span, 176'-long, double-intersection Pratt (Whipple) truss bridge is supported on stone abutments with concrete repairs. The truss is traditionally composed with built-up compression members and eyebar tension members. The upper chords are toe-out channels with coverplate and battens. The verticals are toe-out channels with lacing. The diagonals are eyebars with loop-welded eyes. The lower chord eyebars have forged eyes. The interior panels have a mid-height strut of toe-out channels with lacing. The upper lateral bracing is composed of I-sections with a U-shaped clip to form the connection with the upper chords at the pins. The A-frame lattice portal bracing features decorative cast-iron moldings at the base of the brackets. U-shaped hangers at the lower panel points pick up built-up floorbeams. The floorbeams carry rolled stringers and a steel deck pan (non original). The bridge has pipe railings with many sections missing.
The ca. 1885 double-intersection Pratt truss is a technologically significant example of an increasingly uncommon truss type/design. The builder is undocumented by available county records. Double-intersection Pratt trusses, also known as Whipple or Murphy-Whipple trusses, were among the most successful of long-span thru truss designs (up to 300’ long) of the 1860s to 1890s for both railroad and vehicular crossings. Surviving examples are uncommon nationally and considered technologically significant; Ohio with at least 14 identified examples dating from 1881 to 1898 (Phase 1A survey, 2008) has a very high number in comparison to most other states. The truss design is characterized by diagonals that extend over two panels. In 1847, Squire Whipple, one of America’s foremost bridge engineers, developed the design figuring that the double-intersection configuration increased the depth of panel without altering the optimal angle of the diagonals, thus allowing for increased span length. His design was further refined in 1859 by John W. Murphy, the talented chief engineer of Pennsylvania’s Lehigh Valley RR, who substituted wrought-iron pins for cast-iron connecting pieces, thus developing the connection detail that would prove to be advanced construction practice for this and other truss designs for the next several decades. Ohio’s surviving examples, which mostly date to the 1880s, were not cutting edge for their time, but they show how the form had evolved into the preferred long-span thru truss design of the period. Most have documented associations with prominent Ohio-based fabricators.
There are at least 14 examples of the bridge type important to the development and maturation of the pin-connected thru truss bridge (Dec. 2009). They date from 1881 and concentrate in the 1880s. Even though there are more than 12 extant examples in Ohio, each built in the 1880s has high significance based on overall scarcity (everywhere but in Ohio) of the design. This is a major and technologically significant bridge type. The bridge has high historic significance.

so cool! built in 1885? thanks for posting!
I rode across this bridge with my parents in the 1970's. That's hard to imagine looking at it now, but it was open for a long time after it was bypassed. Not sure when it closed, late 70's or early 80's. The last posted limit on it was 3 tons. Wish some benefactor could come along for it like the Loughery Creek Triple Whipple in Indiana.

Me and a few friends have been there and looked around and it was very cool. Believe it or not we even jumped off of it . We jumped from the top part and it was scary. I have a friend named Nixon and he is about 350 pounds and he even jumped from the very top part.
