June 30, 1897, Hunterdon Republican: The Cost of a Bridge. Sealed proposals for the steel bridge to be built over the Lackatong Creek at Strimple’s mill, west of Sergeantsville, were opened by a Committee of Freeholders last Saturday. Ten iron companies bid and the lowest was $850 by the Canton, Ohio, Wrought Iron Co. The mason work went to Mr. J. C. Wyckoff, of Annandale at $4.10 per cubic yard and the lumber contract was jointly awarded to Joseph Williamson and William Hartpence, each bidding $3.40 per hundred feet. The amount of lumber necessary is 3,232 ft., costing $109.89

From the county survey: "The single-span pin-connected Pratt thru-truss bridge is supported on random ashlar abutments with U-type wingwalls. The trusses appear to be original with the exception of the floor beams, stringers and deck that have been recently replaced, the addition of welded corner braces to the top laterals, and welded braces extending from the portal struts to the exterior floor beams. The trusses are pin-connected throughout. The portals and top chord consist of two channels, a cover plate and lacing. The intermediate verticals consist of two channels with lacing. The lacing on the verticals parallels the bridge centerline. The bottom chord eyebars and diagonal eyebars have forged eyes. The counters are provided with sleeve nuts for adjustment. The end panel vertical hanger has a fourprong, claw-like ends which engage the pins directly over and in line of the U-bolt floor beam hanger. Such an arrangement, also seen on King Bridge Company spans from the same era, means that the hangers are out of phase or reversed. The expansion bearings consist of nested rollers."
