By July 2016, over $ 475,000 (in grants and donations) had been raised and approval had been granted for the building of a replica bridge.

80-463: A motor vehicle, on approximately January 8, 2010. It subsequently reopened to traffic with the replacement parts easily visible. Until 2013, White's Bridge was arguably the oldest covered bridge still using parts of the original structure in Michigan. On July 7, 2013, the bridge burned down. The police suspected arson, and the official cause was placed under investigation. As of July 23, 2013, it

100-413: Is 14 feet (4.3 m) wide and 117 feet (36 m) long. All of the truss members and planks, sheathing, and other dimensional lumber were originally hand hewn and secured with wooden pegs, although the bridge had subsequently been strengthened. The sheeting and roof boards were fastened to the rafters with hand-cut nails. The abutments were made of local fieldstone. Brown truss The Brown truss

120-418: Is a box truss that is a through truss (as contrasted with a deck truss ) and consists of diagonal cross compression members connected to horizontal top and bottom stringers. There may be vertical or almost vertical tension members (the diagram shows these members, while the patent application diagram does not) but there are no vertical members in compression. In practice, when used in a covered bridge ,

140-605: Is a 120-foot-long (37 m) Brown truss covered bridge , originally erected in 1869 in Keene Township, Michigan , United States , near Smyrna on the Flat River . Carrying Whites Bridge Road across the Flat River, it is located north of the Fallasburg Bridge and south of Smyrna. The original bridge was among the area's best-known 19th century structures. The bridge was completely destroyed by fire, on

160-491: Is of the through-truss type with a gable roof. The hand-hewn trusses are sheeted over with rough pine boards. Wooden pegs and handcut square iron nails are used to secure the various parts of the bridge. White's Bridge has been in constant use since 1867, proof that it was well made. The bridge uses the Brown truss system, a through truss consisting of diagonal compression beams and almost vertical tension members (slanting in at

180-539: The Fallasburg Bridge , and Joseph H. Walker to build the bridge for a deferred payment of $ 1000 due in 1870, and $ 700 due in 1871. The builders used second-hand lumber in an effort to contain costs and finish quickly (the bridge was built in 84 days with only manpower and animal power). The townspeople reportedly discovered auger holes in the floor planking and withheld $ 25 from the first payment. Except for occasional siding and cedar roof shingle replacement, White's Bridge retained its original form and structure. The bridge

200-490: The White family, prominent pioneers of the day. The original bridge, built in 1840 by Levi T. White and his sons, was a corduroy bridge made of logs. A second bridge, built about 1856, reportedly at a cost of $ 250, was destroyed by an ice jam during the spring breakup of 1869. The residents of Smyrna sought a replacement with plans to pay for it with a deferred payment. The residents contracted with Jared N. Bresee, builder of

220-501: The improved strength over previous trusses that had members ("braces" in his terminology) come to the horizontal chord near to each other but not exactly together (at "gains" in his terminology), by having several members come together in the same place. From the patent text: I do not claim broadly furnishing the main or counter braces with gains and passing them between the timbers of the chords; What I do claim as my invention, and desire to secure by letters Patent, isβ€” Providing each of

240-449: The last of its kind in Michigan, was built in 1867 by Jared N. Brazee and J. N. Walker, builders of several covered bridges in this area. The name of the bridge derives from the White family, a prominent pioneer family. The crossing of the Flat River here was known as White's Crossing before the first primitive bridge was built. In 1840, a bridge of log corduroy construction was erected. It was replaced by this covered bridge, costing $ 1700. It

280-502: The main and counter braces with two gains at top and bottom, and each of the timbers of the chord with a gain at the point where the braces are applied corresponding with the gains in the braces, and the braces thus formed up between the timber, with the gains of the braces in such relation to the gains of the timbers that when the timbers of the chords are brought together they are combined and become, as it were, only one piece, no part of which can be operated upon or affected independently of

300-456: The morning of July 7, 2013 (police deemed the case arson). In July 2016, approval was granted for rebuilding a replica bridge, which was completed in April 2020. White's Bridge was the third bridge across the Flat River at or near this location south of Smyrna, which was a crossing point or ford , even before the bridges were built. The "Whites Bridge" and "Whites Crossing" names are taken from

320-464: The most common application, the truss is protected with outside sheathing. The floor and roof are also trusses, but are horizontal and serve to give the truss rigidity. The bottoms of the diagonals tend to protrude below the sheathing. The Brown truss is noted for economy of materials as it can be built with very little metal. Brown's patent claims did not actually address the economy afforded by lack of vertical members ("braces"). Instead he focused on

340-645: The top toward the center of the span). This system was patented by Josiah Brown of Buffalo, New York , in 1857. The Brown truss is similar to the Howe arrangement of "X" bracing and counter bracing, but uses lighter members and less timber. It contains no upright compression members and no iron except for bolt connectors at the timber intersections. Builders used the Brown truss successfully in at least four covered bridges in Michigan, two of which ( Ada Covered Bridge , Fallasburg Bridge ) are still in existence. The Brown truss

360-504: Was listed with the Michigan State Register on February 17, 1965. It was awarded a Michigan Historical Marker (site L0042) on July 2, 1965. The bridge was briefly closed in 1995 to allow for repair of the abutments. It was subsequently reopened to automobile traffic. The bridge, with a load limit of 3 short tons (2.7 t) in effect, was in use until it incurred major structural damage, presumed to have been caused by

380-604: Was reported in The Greenville Daily News , that the fire of July 7, was indeed an arson. Crime lab tests confirmed the presence of an accelerant. Investigation is ongoing. A group started to raise funds for rebuilding the historic bridge. On April 16, 2015, the Whites Bridge Historical Society announced that the funds had been secured to rebuild a replica bridge that would be open to traffic in 2016. This funding will include

400-399: Was thus briefly popular in Michigan but did not gain wide acceptance elsewhere. The bridge rests on concrete and fieldstone footings at each end. As typical for covered bridges, it is a frame structure with a gabled roof that is covered with creosote shingles. Its construction is of the through-truss type, and the trusses are completely sheathed on the outside with rough pine boards. The floor
