For shorter spans, simple bridges are suitable.

Simple bridge is like simply supported beam type which consist two supports at its ends. Types of Bridges based on Inter Span Relation Otherwise roadway on top deck and railway in bottom deck is preferred. If one floor is there then, rail and road way are arranged side by side. This type of bridge is useful for both road way and railway transport. Truss type bridges are preferred for railways but how ever r.c.c bridges are also used.Īqueduct bridges are nothing but water carrying bridges which are constructed to0 transport water from source to system. Rail bridges are constructed for rail transportation. Girder type bridges are used as highway bridges over rivers or canals. These are constructed over rivers or another routes to allow road way traffic. High way or road Way Bridge is used for road transportation. This is called under bridge.įoot Bridge is generally constructed for humans to cross the roads or rail route or any canal by foot. If over bridge is not possible, an underground type bridge is constructed to pass another route. This is called over bridge or fly over bridge. To pass over another route (railway or highway), a bridge is constructed to allow traffic. Types of Bridges based on Level of Crossing When the span of bridge is more than 120 meters then it is termed as long span bridge.

If the bridge span length is in between 8 to 30 meters, then it is called minor bridge.įor major bridge, the span is generally about 30 to 120 meters. When the bridge span length is below 6meters then it is called as Culvert Bridge. These blocks are suitable for shorter span to longer span bridges. To construct pre stressed concrete bridge, pre-stressed concrete blocks are arranged as deck slab with the help of girders. If concrete material is placed under compression before applying the loads, then it is called as prestressed concrete. They can bear heavy loads and are widely using nowadays. R.C.C bridges are constructed using reinforced cement concrete. These are more durable and bear heavy loads. Steel bridges are constructed using steel bars or trusses or steel cables. These are generally constructed for short spans and in low depth canals. Masonry Bridge constructed by using bricks or stones. These are generally constructed for short spans or as temporary bridges. For long span bridges, this type of suspension is suitable.īridges constructed using timber are called timber bridges. In case of Suspension bridge, deck slab is suspended with the help of cables and suspenders. There are several types of trusses are available. In case of truss bridge the super structure is provided with trusses. Truss is member consisting connected elements to form triangular units. Load coming from the deck are taken by girder and transferred them to the piers and abutments. The girder may be of rolled steel girder or plate girder or box girder. In case of Girder Bridge, the deck slab is supported by means of girders.

In some cases, the arch may be under the deck slab also. There are many types of arch bridges are there. Types of Bridges based on Type of Super StructureĪrch bridge is curve shaped bridge, in which horizontal thrust is developed and is restrained by the abutments at each end of the bridge.
