    CUTLER BRIDGE HAER IA (Donahoe Bridge) IA Winterset City Park Winterset Madison County Iowa 5 Ithiel Town, A Description ofIthiel Town's Improvement in the Construction of Wood and Iron Bridges. New Haven: S. Converse, History of iron and steel bridges. Each new material or design technique builds off the lessons of the past. Modern bridges often use steel in the form of cables or girders, and/or concrete as construction materials. Steel is durable and is relatively light considering the strength and size of the components.

    Relatively few covered bridges survived into the early years of the 20th century. Most of them reflected the evolution in design of three pioneers in the annals of bridge construction: Theodore Burr, who patented the Burr arch bridge in ; Ithiel Town, who patented the Town lattice design in Town lattice truss. The town lattice truss was designed by Ithiel Town and patented in It consists of a lattice of web members, crossing at an angle of 45 to 60 degrees, connected by wooden pins to horizontal top and bottom cords. There are no vertical members dividing the town truss.

      The Pratt truss was proprietary in by 2 Bean Town railway engineers, Caleb Pratt and his son Thomas Willis Pratt. The design uses vertical members for compression and diagonal members to reply to tension. The Pratt truss style remained well-liked as bridge designers switched from wood to iron, and from iron to steel. the National Design Specification for Wood Construction (NDS). 26 The NDS is the most widely recognized general specification for timber design and is published periodically by the National Forest Products Association. The specification includes design requirements and tabulated design values for sawn lumber, glulam, and timber Size: 1MB.

On Januarchitect Ithiel Town was granted a patent for a wooden truss bridge, also known as Town’s Lattice Truss. An architect and civil engineer, Town had already built the first covered bridges to span the Connecticut River, one at Hartford and two in Massachusetts at Springfield and Northampton.

Many later covered bridge truss types used an added arch based on the success of the Burr truss. The Town lattice truss was patented in by Ithiel. The Construction of Iron Bridges. As bridges and the method of constructing them are becoming objects of great importance throughout the United States, and as there are at this time proposals for a bridge over the Delaware, and also a bridge beginning to be erected over the Schuylkill at Philadelphia, I present the public with some account of the construction of iron bridges.

Connecticut architect Ithiel Town received a patent for a truss of crisscrossed diagonals, or lattice, in Howe Truss In Massachusetts builder William Howe introduced iron into wooden truss design by substituting adjustable iron rods for he vertical members of Long's truss.

Truss bridge, bridge with its load-bearing structures composed of a series of wooden or metal triangles, known as trusses. Trusses are capable of supporting considerable external loads over a large span and use a relatively small amount of material, making them particularly useful for railroad and military bridges.

A lattice bridge is a form of truss bridge that uses many small, closely spaced diagonal elements forming a lattice. The lattice Truss Bridge was patented in by architect Ithiel Town.

Originally a design to allow a substantial bridge to be made from planks employing lower–skilled labor, rather than heavy timbers and more expensive carpenters, this type of bridge has also been constructed using Ancestor: Truss bridge. increasingly used creosote rather than covering wooden truss bridges.

In Ithiel Town received a patent for the Town lattice truss, the first true truss that acted independently of any arch action (Hayden ). Interestingly, it seems that Town more actively pursued selling his .Wood was probably the first material used by humans to construct a bridge. Although in the 20th century concrete and steel replaced wood as the major materials for bridge construction, wood is still widely used for short- and medium-span bridges.

Part 4 There was another bridge on a similar principle erected near the same place incalled the "Market Street Bridge," which consisted of three arches, the centre one being feet span, and the other two feet span, with a breadth of roadway of 35 feet.
