| | Parker pony truss bridge |
The skewed, 1 span, 146'-long, riveted Parker pony truss bridge has built-up chords and rolled I section web members. The end posts are vertical, not sloped, as is characteristic of most Parker trusses of this period. The gusset plates have been shaped to have curvilinear edges, rather than straight edges, giving them a "webbed" appearance. The bridge has rolled floor beams, stringer, and a concrete deck. The deck was replaced in 1985 and safety shape barriers placed to the roadway faces of the trusses. The bridge is supported on concrete abutments with U-shaped wingwalls finished with balustrades.
Integrity:
The bridge was rehabilitated in 1985. Summary of Significance: The Parker pony truss was fabricated by the Mt. Vernon Bridge Co. for the state highway department in 1935. It is a well-proportioned, although technologically late, example of the bridge type/design. It has nice aesthetic detailing, including the gusset plates and wingwalls. It speaks well of the bridge bureau's attention to design under the leadership of D. H. Overman. There is a similar thru truss in Richland County on SR 13 (7000243). The bridge was rehabilitated in 1985, which included replacing the deck. The project does not appear to have diminished the integrity or the ability of the bridge to convey its significance, and it was approved with no adverse effect by the SHPO. The prior inventory included the bridge in the reserve pool. It is recommended eligible. Camelback and Parker trusses are members of the Pratt-family of trusses with sloped top chords Technologically, Camelback and Parker trusses differ only in the number of top chord slopes (Camelbacks have exactly five slopes, and Parkers have more than five slopes.) The sloped-chord trusses provide the greatest depth at midspan where it is needed to accommodate the stresses, meaning that less material is needed in their construction as compared to a parallel chord truss of similar span, but fabrication is made more difficult due to the varying lengths of the members. The sloped-chord trusses are often associated with longer spans where the savings in material is great enough to be worth the additional fabrication costs. The practice of sloping the top chords dates to at least the 1840s and appeared early in the development of metal trusses. As with other truss designs, pin connections were used from the 1870s to 1900s, and mostly phased out during the 1910s. Rivet connections were being used by the early 1900s and were prevalent from the 1910s to 1940s. Standardized rivet-connected Camelback and Parker designs were used by many state highway departments, including the Ohio State Highway Department.

| | US Route 36 Camelback Rivited Thru Truss two center spans |
The bridge currently carries a 2 lane US highway over the Tuscarawas River south of Gnadenhutten. It is paralleled by a similar 2-span thru truss railroad bridge.
The 4 span, 509'-long bridge has two rivet-connected Camelback thru truss main spans (220 ft long each and 34 ft wide) flanked by steel stringer approach spans (30’ each). The trusses are composed of rolled sections for the web members and built-up sections for the chords. It has cantilevered sidewalks with state-standard metal panel railings.
The bridge is available as one individual truss span if that is all that is needed at a new location (approx. 200’). Any interested parties will have to contact us no later than 03/01/15. We anticipate the bridge will be available for pick-up between 04/01 – 06/30 2016. The salvaged bridge components will include the bridge truss components but no deck.

| | Marion 141 Truss (St James Road Bridge) |
The complete bridge is available for immediate use. It is currently being stored at the Kings Mill Golf Club (40.354800 / 83.022700), with easy access to load onto CR 141. A great opportunity to preserve the National Register of Historic Places-eligible, St. James Road Bridge, a Parker pin-connected, thru truss bridge, which carried County Route 141 (St. James Road) over the Olentangy River in Richland Township, Marion County.
The bridge dates to about 1905 and was moved to this location as part of a WPA project in the 1937. The ca. 1905 pin-connected Parker thru truss bridge ranks as 1 of the 2 oldest examples of the Parker or Camelback design in Ohio [NB -- the oldest (SFN 07XXXX1, 1893) in Belmont County over the Ohio River Back Channel (owned by WVDOT) is slated to be demolished later this year]. It is technologically significant as on Ohio's most complete surviving examples of a sloped-chord, long-span, pin-connected highway truss bridge with typical period detailing (Criterion C). Although the truss bridge is dated 1937 by a plaque, the bridge's steel truss superstructure actually dates ca. 1900 by style, design of its members, pin connections, and its 16' deck width. According to county records, the bridge was relocated here from State Route 4 (Marysville-Marion Road) over the Scioto River in 1937. Marysville-Marion Road was taken into the state highway system as State Route 115 about 1911 and renamed State Route 4 about 1921. County highway maps from 1914 and 1919 show a bridge crossing the Scioto River at that location. The truss bridge was in all likelihood originally a county bridge prior to being taken into the state system in 1911. It was returned to county ownership when it was relocated in 1937. The salvage and relocation of old truss bridges was (and still is) a common practice, and this portability was one of the "selling points" of the technology. The original date of construction and fabricator are not noted by available records. The Parker design, with its polygonal upper chords, which save material and concentrate depth at the center of the center of the trusses where it is needed, is used because of the nearly 200' length of the span. |

| | Ridge Road Pony Truss |

1-span (52 Feet) Warren Welded Pony Truss. Located on TR 114 (Ridge Road) over
East Branch Huron River in Bronson Township, Huron County
(Lat/Long: 41.092088 / 82.380300).
This
bridge is an early version of the design conceived by Herman Rogovin, which
became the most popular post-World War II truss design in Ohio and still is an
important part of US Bridge Company’s catalogue; installing bolted and welded
versions, internationally, as the Cambridge.
The
bridge will be available March 2020 based on the current project schedule
(HUR-TR 114-6.43 PID: 93990).
NOTE: This bridge is only available to a public agency.

1885 1- span Double
Intersection Pratt (Whipple) Truss, 225 ft. long 16 ft. wide, 18.5 ft.
vertical clearance. Bypassed State Route 762 over Big Darby Creek (Lat/Long:
41.092088 / 82.380300).
225-foot,
single span, 15-panel, double intersection Pratt (Whipple) truss with built-up
compression members and eyebar or rod tension members. It has built-up lattice
portals with urn finials and decorative builder’s plaques. The upper lateral
bracing has decorative quatrefoil cut outs. Due to the great depth and length
of the truss, there is lower lateral bracing composed of rods with turnbuckles.
The floorbeams are supported from the lower chord pins by U-shaped hangers. The
floorbeams carry metal stringers and a timber plank deck with asphalt wearing
surface. The bridge is supported on ashlar stone abutments.
This
bridge is eligible for the National Register under Criterion C as an 1880s
example of the technologically significant Pratt double intersection truss,
also known as the Whipple truss or the Murphy-Whipple truss. Whipple
trusses are uncommon nationally, and although there were 14 surviving examples
of Whipple truss bridges in Ohio as of 2009, each of these examples is
important due to the nationwide scarcity of this truss type. This bridge
is also significant under Criterion C as a rare example of work by the
Cleveland Iron Bridge Company, which appears to have only been in business a
short time during the 1880s. The bridge has been bypassed, has undergone
some welded repairs, and strengthening measures, and the wood deck is in poor
condition. However, the structural portion of the bridge has a good level
of integrity.
