what is the regularly span of a arch bridge
A truss is a diagonal brace which provides structural support for a bridge span by extending between a vertical member and the bridge span.
Double-Span Metal Pratt Truss Bridge was created in 1877.
the longest span of a truss bridge is 2.1 miles long
well now a days truss bridges are not in use oftenly cause they need great maintenance works truss bridge only gives advantage to short span way it cannot be use in a big way
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
The Warren truss is commonly regarded as one of the strongest types of truss bridges due to its efficient use of materials and load distribution. Its geometric design helps evenly distribute forces throughout the structure, making it a popular choice for long-span bridges.
Glenville Truss Bridge was created in 1885.

Triangels are the strongest shape so make a triple triangle design i aced it that way +++ The plank bridge is the weakest as it is just a simple beam with no central support or stiffening for the span. The other two can be designed to comparable strength for a given span, but work in somewhat different ways: the truss bridge acts as a beam stiffened by the truss frames, the arch transmits the forces from the centre to its abutments.
The type of bridges are: -truss bridge -arch bridge (truss arch bridge) -suspension bridge (suspension truss bridge) -cantilever bridge
