The Lower Shavertown Covered Bridge is a rare and substantially intact example of rural vernacular bridge design and construction in the Catskill region. Originally erected in 1877 to cross Lower Beech Hill Brook at Shavertown, in 1954 the span was moved 15 miles to its present location at Methol. Constructed of native materials, the 42-foot, single-span structure incorporates the patented Town lattice truss design; it is one of only 10 examples of its type and method of construction remaining in New York State. Saved from destruction during the construction of the Pepacton Reservoir, this small span is a rare surviving structure associated with the inundated Shavertown community. At its present location on a private road, the Lower Shavertown Covered Bridge remains in active use as a vehicular bridge.

Shavertown was first established by Captain Peter Shaver in 1784. Situated in the remote and sparsely settled town of Andes, Shavertown was located between the junctions of the Tremperskill and Lower Beech Hill Brook with the East Branch of the Delaware River. Forest products quickly became the chief output of the area. The heavily forested, mountainous Catskill region is laced with deep defiles and plunging streams. The few roads that existed required numerous spans, which were constructed by local housewrights and joiners from abundant native timber and stone.

Erected by Delaware County builders Anson Jenkins and August Neidig of Union Grove, the Lower Shavertown bridge of 1877 incorporates the lattice truss design patented in 1820 by Ithiel Town. The bridge remained in use on its original site until 1954, when it was threatened with destruction. Proposed expansion of the vast New York City water supply system into the Delaware River watershed would require the construction of the Pepacton Reservoir. The communities of Shavertown, Union Grove, and Arena would be inundated beneath the new reservoir. Area resident Carl Campbell dismantled the structure, transporting it by truck across the mountains a distance of 15 miles to Methol. Here the bridge was reassembled to carry a private road over Trout Brook.

Although hundreds of covered wood truss bridges were built throughout New York, only 24 remain.

The history of covered timber bridge construction in New York State spans the period from the first decade of the nineteenth century to the era of the First World War. The earliest known extant covered bridge was built in 1825; the latest in 1912.

Throughout much of the nineteenth century, New York was predominantly rural; its settlement pattern generally consisted of widely separated communities whose economy was based upon subsistence agriculture and local water-powered industry. Few improved roads connected population centers. As the Empire State grew and its economy expanded, however, road and bridge improvements became essential for linking emerging centers of civic market activity.

The earliest permanent bridges in New York were constructed using readily available local materials and skills. Because the cost of constructing bridges generally was the responsibility of local governments, they turned to readily available materials and skills for this purpose. The abundant timber and stone resources found throughout much of New York State made these materials the logical choice for bridge construction during the period of significance. The relative ease of construction was another factor that mitigated in favor of wooden bridge construction. The timber framing skills of local millwrights and joiners were readily adaptable to the construction of timber bridges.

During the Colonial period, the first timber bridges incorporated the Kingpost or the Queenpost truss configuration. These simple, open structures with plank decks were widely erected across small streams, though their use was limited to clear spans less than fifty feet in length. Longer crossings were possible using multiple spans supported by mid-stream piers or timber cribbing. The open timber truss bridge remained an inexpensive and popular form for farm bridges and crossings on minor roads until the early twentieth century, when it was supplanted by the metal span. The open trusswork was sometimes sheathed with protective weather boards to preserve the life of the truss. Because of its horizontal top chord, it was possible to cover a Queenpost truss bridge with a protective roof. The Copeland Covered Bridge (1879), a farmer's bridge in rural Saratoga County, is an extant example of a covered Queenpost truss bridge remaining in New York.

From the early decades of the nineteenth century, the cost of building and maintaining timber bridges generally fell upon local governments or state-chartered bridge or turnpike companies, which were established as for-profit ventures. It soon became evident that protecting the bridge's structural system from the elements would reduce the burden of maintenance and replacement costs. This protection was most readily achieved by covering the timber truss bridge with a roof and board sheathing to enclose the frame structure.

During the Federal period, inventor Theodore Burr (1772-1822) designed a highly successful long-span bridge form that combined the structural advantages of a simple timber truss with a relieving arch. Burr patented his timber truss design in 1817. His first successful bridge was a four-span structure erected across the Hudson River at Waterford, New York in 1804. Built of hand-hewn pine structural members, the Waterford bridge was sheathed with pine plank siding and covered by a shingled roof. Burr's bridge stood for more than a century until it was destroyed by fire in 1909. The Burr Arch Truss is represented in New York by three extant historic covered bridges: Perrine's Bridge (1844), Ulster County, Salisbury Center Bridge (1875), Herkimer County, and the Hyde Hall Bridge (1825), Otsego County.

A successful truss design nearly contemporary with the Burr truss was the Town lattice truss, patented in 1820 by the versatile builder/architect Ithiel Town (1784-1844). Consisting of a horizontal top and bottom chord connected by a web of closely spaced, alternating diagonal timbers, the Town lattice truss included no vertical members; the required stiffness was achieved by connecting the intersecting diagonals with wood pins. Carried on piers placed at intervals, bridges incorporating the Town lattice truss could span considerable distances. Its inherent strength coupled with its ease of construction made the Town truss design a popular design for highway and early railroad bridges until the post-Civil War era. The covered bridges at Eagleville and Shushan, Washington County, are notable examples of the Town truss form.

During the 1830s, Colonel Stephen H. Long (1784-1864) of the U.S. Army Corps of Topographical Engineers perfected a rigid timber truss form that incorporated panels consisting of intersecting diagonals and counters. Long's initial patented design of 1830 for an "assisted truss" included a redundant Kingpost relieving truss above the center panel points (where the greatest flex would occur). With practical experience, Long refined his design to eliminate its "overbuilt" characteristics, receiving additional patents in 1836 and 1839. The Old Blenheim Bridge (1855), Schoharie County, (destroyed 2011) was a notable example of the Long truss design.

The final major timber truss design to achieve widespread popularity during the late nineteenth century was first patented in 1840 by William Howe (1803-1852). The Howe truss consisted of horizontal timber top and bottom chords and diagonal wood compression members combined with vertical tension members made of wrought iron. The ends of the iron tensions rods were threaded and secured to iron shoes at the panel points of the web. The inherent properties of wood and iron as construction materials were effectively used in Howe's truss; this hybrid truss became the most widely constructed, standard American timber bridge form of the nineteenth century. The Rexleigh (1874) and Buskirk (1857) Covered Bridges in Washington County and the Jay Covered Bridge (1857), Essex County, are Howe truss structures.

By the third quarter of the nineteenth century, the covered timber truss bridge was being supplanted by the manufactured metal truss bridge on the roads and rail lines of New York State. Stimulated by wartime growth and development, iron manufacturers turned to production of standardized metal bridge components in the post-Civil War era. The increased strength, ease of construction, and reduced cost associated with metal bridges won favor among local governments and railroad companies; by the 1880s, the heyday of wooden bridge-building had passed. Although several examples of covered timber truss spans remain from the early twentieth century in rural areas of New York, the advantages of iron bridges were clearly understood and widely applied well before 1900.

Bridge Description

The Lower Shavertown Covered Bridge is located north of the hamlet of Methol, Delaware County. The wood plank framed, gable-roofed, single span is situated on a private drive as a crossing of Trout Brook. The bridge is oriented with its portal ends facing east and west. This small structure originally was erected in the hamlet of Shavertown in 1877 as a crossing of Lower Beech Hill Brook. The bridge remained at this location until 1954, when it was dismantled and moved 15 miles because of impending destruction from the creation of the Pepacton Reservoir. The present setting of the bridge is a remote and picturesque area of the Catskill Mountains, characterized by sparse settlement and widely scattered buildings mostly used on a seasonal basis.

The general dimensions of the Lower Shavertown Covered Bridge are as follows:

Overall length: 32' (span length less portals)
Overall width: 23'
Deck width: 13' 5"
Portal height: 12'
Portal width: 12' 10"

The timber bridge is a single span carried on abutments built of dry-laid fieldstone capped with concrete. The web of the superstructure incorporates the Town lattice truss. Heavy paired planks form the top and bottom chords. Planks also form the intersecting diagonal members, which are joined by paired wood pins ("trunnels") driven through each point of intersection. Long floor beams extend beyond the width of the truss at both ends to support a pair of small timber buttresses projecting from each side. The portal shelters projecting beyond the ends of the truss extend the ridge of the gable roof and are supported by diagonal bracing timbers. The deck consists of planks laid lateral to the truss on stringers. The entire bridge is sheathed in vertical board and batten siding attached to horizontal nailers. The roof consists of nail strips covered with corrugated metal sheathing.

When the bridge was moved to its present location in 1954, its overall length was reduced by 10 feet because the end portals were deteriorated. Beams were replaced, new abutments were constructed, and new portals closely resembling the originals were added.
