1. Straight Alignment:When the

alignment of bridge isperpendicular to thecentre line of a river, itis called straight bridge.

2. Skew Bridge:When the

alignment of a bridge isnot perpendicular to thecentre line of river, iscalled Skew Bridge.

1.Deck Bridge:

When the bridge flooring is providedat the top of the super structure, it iscalled deck bridge.

2. Through Bridge:When the bridge

flooring is provided atthe bottom of the superstructure, it is calledThrough Bridge.

3. Semi-Through Bridge:When the flooring

is located at someintermediate level in thesuper structure, it iscalled Semi-ThroughBridge.

1. Aquaduct:

It is small bridge constructedover a stream which remains dry for mostpart of the year is called aquaduct.

2. Viaduct:It is a long continuous

structure which carries aroad or railway like bridgeover dry valley composed ofa series of spans trestlebents instead of solid piers.

3. Grade separator:When two roads crosses

each other and there isconsiderable differences intheir formation level, abridge structure isconstructed , which is knownas grade separator.

4. Highway Bridge:It is constructed on a

roadway for the movementof vehicles.

5. Railway Bridge

It is constructed for the railway.

6. Foot Bridge

A foot bridge is a bridge exclusively usedfor carrying pedestrians, cycles and animals.

7. Pipe Bridge

It is used to support pipeline for water, gas,oil, etc.

1. Slab Bridge:When the span of

bridge is 3 to 6m, slabbridge is used, It is alsocalled culvert.

2. Girder bridge:When the span of a

bridge is more, flooringis supported on RCC orsteel girder. Such typeof bridge is calledgirder bridge.

3. Truss Bridge

When the flooring of a bridge is supportedover steel trusses it is called truss bridge.Normally such type of bridges are used forrailways.

4. Suspension Bridge:

Suspension bridges consists of sets ofcables hanging in a curve from which theroadway is supported.

A flooring load is transferred suspendersand cables to the piers.

Narmada bridge

5. Arch Bridge:

In such type of bridge the weight offlooring is transferred to the piers through thearch. the floor beam is suspended troughhangers from arch.

1.Submersible bridge orcauseway:

A road causeway is apucca dip which allowsfloods to pass over it. It mayor may not have openings orvents for low water to flow.

2. Non-Submersible bridge:In this types of bridge

formation level is kept abovethe HFL, so that maximumflood does not affect thetraffic on the bridge.

1. Simply supported Bridge:

When the bridge girders are simplysupported on piers, it is known as simplysupported bridges.

2. Continuous Bridge:

When the super structure of a bridge iscontinuous over more than two supports, it iscalled continuous bridge.

3. Cantilever bridge:

A cantilever bridge is formed of cantileversprojecting from the supporting piers. The endsof a cantilever bridges are treated as fixed.

4. Balanced cantilever bridge:

A balanced cantilever bridge consists ofspans simply supported over cantilever.

Forth Bridge,United Kingdom, Edinburgh,

1. Culvert - span up to 8m.

2. Minor bridge – span 8 to 30m.

3. Major bridge – span 30 to 120m.

4. Long span bridge – span above 120m.

1. Swing bridge:

In case of swing bridge a central pier isprovided with suitable bearing or rollers. Thesuper structure consists of a pair of steeltrusses and it can be rotated in a horizontalplan about vertical axis.

2. Bascule bridge:

In case of bascule bridge, the entirestructure is rotated in a vertical plane about ahorizontal axis.

Lowestoft

3. Traverser bridge:

In case of traverser bridge, it is so arrangedthat the whole bridge can fully or partially be rolledforward or backward across the openings.

4. Lift bridge:

In this type of bridge the truss is lifted up.

5. Transporter bridge:

In case of transporter bridge, a moving cage issuspended from an overhead truss with the help ofcable or wire ropes.

b. boat bridge : COLKATA-RABINDRANATH SETU

c. flying bridge- West India Quay

London, UK

2. Permanent bridge:

a. RCC bridges
