The Miami and Erie Canal was a 274-mile (441 km) canal that ran from Cincinnati to Toledo, Ohio, creating a water route between the Ohio River and Lake Erie. Construction on the canal began in 1825 and was completed in 1845 at a cost to the state government of $8,062,680.07. At its peak, it included 19 aqueducts, three guard locks, 103 canal locks, multiple feeder canals, and a few man-made water reservoirs. The canal climbed 395 feet (120 m) above Lake Erie and 513 feet (156 m) above the Ohio River to reach a topographical peak called the Loramie Summit, which extended 19 miles (31 km) between New Bremen, Ohio to lock 1-S in Lockington, north of Piqua, Ohio. Boats up to 80 feet long were towed along the canal by mules, horses, or oxen walking on a prepared towpath along the bank, at a rate of four to five miles per hour.

The Lynchburg Covered Bridge is a historic wooden covered bridge that spans the east fork of the Little Miami River in Lynchburg, Ohio. It, also, has the distinction, following a recent repair and restoration project, of being the only such covered bridge in North America to have been converted to a pseudo-suspension infrastructure. The bridge was built in 1870 as a Long truss.
The Ashuelot Covered Bridge is a historic wooden covered bridge over the Ashuelot River on Bolton Road, just south of its intersection with NH 119 in Ashuelot, an unincorporated village of Winchester, New Hampshire. Built in 1864-65, it is one of the state's few surviving 19th-century covered bridges. It was listed on the National Register of Historic Places in 1981.
The Bement Covered Bridge is a historic wooden covered bridge on Center Road over the Warner River in Bradford, New Hampshire. A Long-truss bridge, it was built in 1854, and is one of New Hampshire's small number of surviving 19th-century covered bridges. It was listed on the National Register of Historic Places in 1976.
The Harra Covered Bridge is a historic wooden covered bridge in Washington County, Ohio, United States. Located in western Watertown Township, about 2 miles (3.2 km) north of the community of Watertown, the bridge spans the South Branch of Wolf Creek near the intersection of State Route 339 and Township Road 172. Among the bridge's more distinctive features are its cut stone abutments, its metal roof, and the vertical siding. Although it has been open for well over one hundred years, it remains in strong structural condition, and it served daily traffic into the late twentieth century.
The Hune Covered Bridge is a historic wooden covered bridge in the southeastern part of the U.S. state of Ohio. Located northeast of the community of Dart, it spans the Little Muskingum River in northeastern Lawrence Township in the eastern part of Washington County. Local bridge builder Rollin Meredith erected it in 1879, using the Long-truss style of truss bridge design; the single-span bridge was named for the locally prominent Hune family. Among its design features are a metal roof, abutments of cut stone, and vertical siding. As a Long truss, the Hune Bridge is a valuable example of nineteenth-century architecture: few examples of this complicated style survive to the present day. In 1976, the Hune Bridge was listed on the National Register of Historic Places, both because of its place in local history and because of its historically significant construction.
The Hildreth Covered Bridge, also known as the "Hills Covered Bridge" or "Lafaber's Mill Bridge," is a historic covered bridge in Washington County, Ohio, United States. Located off State Route 26 in Newport Township, about 5 miles (8.0 km) east of the city of Marietta, the bridge historically carried Hills Bridge Road over the Little Muskingum River. Construction of the Hildreth Bridge was a long process: the most significant amount of work was done on the bridge in 1878, but the entire construction process occurred between 1871 and 1881. The identity of its builder is unknown.
The Lockington Locks are a group of canal locks on the former Miami and Erie Canal in Lockington, Ohio, United States. Built beginning in 1833, the locks opened for regular use in 1845. The system consists of seven locks: six together at one end, and a seventh at the southern end. Along with features such as basins to allow canal boats to turn around, the locks stretch for 3.75 miles (6.04 km) between Lockington in far southern Shelby County and Washington Township in far northern Miami County.
The Shinn Covered Bridge is a historic wooden covered bridge in the southeastern part of the U.S. state of Ohio. Located in the countryside northeast of Bartlett in Washington County, this single-span truss bridge was built in 1886 by local carpenter Charles T. Shinn. Built of weatherboarded walls with stone abutments and a metal roof, the bridge features vertical siding, and its portals have remained vertical and resisted creeping into another shape. The heart of the bridge's structure employs the Burr Truss design, which mixes the king post truss with a wooden arch designed by Andrea Palladio in the sixteenth century. Shinn built his bridge to span the western branch of Wolf Creek in Palmer Township. Measuring 98 feet (30 m) in length, the bridge was constructed soon after the drowning of one of Shinn's children.
The Root Covered Bridge is a historic wooden covered bridge in the southeastern part of the U.S. state of Ohio. Located off State Route 555 in far northern Decatur Township, Washington County, the bridge was built in 1878 in the Long truss mode of truss bridge construction. Measuring 65 feet (20 m) in its single span, it spans the West Branch of the Little Hocking River.
The Gifford Covered Bridge, also called the C.K. Smith Covered Bridge, is a wooden covered bridge that crosses the Second Branch of the White River in Randolph, Vermont on Hyde Road.

The Eldean Covered Bridge is a historic covered bridge spanning the Great Miami River in Miami County, Ohio north of Troy. Built in 1860, it is one of the nation's finest surviving examples of a Long truss, patented in 1830 by engineer Stephen H. Long. At 224 feet (68 m) in length for its two spans, it is the longest surviving example of its type. It was listed on the National Register of Historic Places in 1975, and was designated a National Historic Landmark in 2016.
The Ponn Humpback Covered Bridge was a historic covered bridge in the southeastern part of the U.S. state of Ohio. Located near the village of Wilkesville in Vinton County, it bore a name derived from its unusual shape: the bridge was arched in the middle, rather than being flat like a typical covered bridge. Declared a historic site in the 1970s, the bridge had a history closely tied to arson — it was constructed to replace a bridge that had been burned intentionally, and it met its end at the hands of an arsonist.
The Keniston Bridge is a historic covered bridge in Andover, New Hampshire, carrying Bridge Street over the Blackwater River. Built in 1882, it is of Town through truss construction, and is one of the few surviving 19th-century covered bridges in the state.
