A licensed engineer can help operators design a safe, appropriate timber bridge. Personnel from Virginia Tech have described in detail how to build a stringer bridge using standard bridge design procedures, for example, by placing timber stringers across the abutment, using a bent to support a trestle or timber frame. Their methods are quick ...
That same year, he established the Howe Bridge Works to build bridges using his design. [4] The first Howe truss ever built was a single-lane, 75-foot (23 m) long bridge in Connecticut carrying a road. [1] The second was a railroad bridge over the Connecticut River in Springfield, Massachusetts.
The bridges are also known as Little Lithodendron Bridge and Lithodendron Bridge. A timber stringer bridge was the cheapest way to span spaces like arroyos. It consists of parallel timber logs laid across timber pile bents. [1] These were by far the most common bridge type built in the state of Colorado, for example, historically. [1]
The M-28–Tahquamenon River Bridge is plate girder bridge built of nine steel girders encased in concrete. [3] The girders are braced by concrete diaphragms and sit on large concrete abutments. The bridge spans 55 feet (17 m), and is 35 feet (11 m) wide with a 30-foot-wide (9.1 m) roadway.
The bridge was one of the first trunkline bridges built that used the Michigan State Highway Department's steel stringer configuration. [2] Of the 22 total trunkline bridges the department listed in its 1913–14 biennial report, almost half were stringer bridges, and of these Pike River Bridge is the only one to remain undemolished and unaltered.
It is one of the oldest surviving iron bridges in the county, one of the few that use both cast and wrought iron and one of only two surviving examples of the Whipple bowstring truss type. In 1971 it was listed on the National Register of Historic Places, the only bridge in the city of Albany so far to be listed individually. [1]
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
The bridge was built in 1916 by the Canton Bridge Co. It was a timber stringer trestle bridge. It has also been known as the Niobrara River Bridge and has been denoted as NEHBS No. CE00-227. [1] When it was listed on the National Register, the bridge was notable as one of few surviving examples in Nebraska of early timber bridge designs.
