Basic Types Of Bridge

 Truss Bridge
 Girder Bridge
 FLYOVER BRIDGE
WHAT IS FLYOVER BRIDGE?
 It is a bridge that carries one road or railway
line above another either with or without
subsidiary roads, for communication between
the two sides.
REASON BEHIND GOING FOR A FLYOVER
 As the traffic on the road goes on increasing and we
don’t have any space left in both the dimensions, then
the only option left will be to go to the third
dimension and that is done through flyover
construction.

CROSSING
Railway Crossing Flyover
 At railway crossing where there is high traffic
congestion in terms of the frequency of trains passing
by or the traffic on the road, in both the cases the
flyover should be provided along the road.
Road Crossing Flyover
Simple Flyovers
 In this case, the main road is used for fast traffic,
which is made to pass at a high level by a bridge,
providing ramps on both the approaches; and the slow
traffic is made to pass underneath. Thus the traffics
pass at two different levels, and leave no chance for an
accident.
 Cloverleaf Crossing Flyover
 It requires a very large area of land. All conflicting
streams of traffic are avoided, and so traffic can move
at its own speed. This is more advantageous than a
roundabout, as there is no necessity for weaving and
slowing down of traffic.
USES OF FLYOVER
 Flyovers play a major role in streamlining the
traffic control system.
 Through flyovers plenty of time is saved avoiding
congestion.
 Pollution effect is reduced.
 Flyovers reduce the risk of accidents
 Flyovers also contribute a lot to the aesthetics of
the city. The persons traveling on the flyover can
enjoy the panoramic view of the city.
NEGATIVE IMPACTS OF FLYOVER
 Flyovers are not as a rule suitable for built up areas as
they require a large area and also it is costly.
 Lack of proper management in the flyover construction
may cause many problems.
 Loss in the case of accidents is increased. The risk of
accidents is reduced but in case an accident occurs the
loss may be more. As the vehicle is at a high elevation,
during accidents there is more chance of losing life.
 As the people who cannot risk their lives in relying on
it are not using it. So, it’s ironical that the flyover has
become a liability here instead of an asset for the city.
 Encroached by squatters
 Wastage of usable space / dead pockets
 Unused large open areas in a high economic value region
 Flyovers require a large area and construction cost is high
 Create undesirable views - Lowering the value of adjacent
properties
 Littered with filth and dumping grounds for garbage / land
misuses such as dumping debris
 Street hawkers
 Criminal activities / abandoning of cars
 At times, not effective usage of flyovers
 Disconnect neighborhoods - Gap within its context
 Make pedestrian crossing undesirable
POTENTIAL OF SPACE UNDER FLYOVER
 Since space under flyover is not always programmed,
and it doesn’t have a territory, it is used by different
sets of people at different point of time.
 It can be either formal or informal public space.
 Uniqueness of flyover than other voids is its character
of overhead shelter.
 Generous longitudinal underneath space which is
barrier free.
 Its sheltered from heat and rain.
 Free from land tenure disputes, real estate and politics.
 Highly visible spaces.
 Breathing zones in urban area
ASSUMPTION
 Kathipara Junction:- Kathipara Junction is an
important road junction in Chennai, India. It is
located at Alandur, (St.Thomas Mount), south of
Guindy, at the intersection of the Grand Southern
Trunk Road (NH 45), Inner Ring Road, Anna Salai
and the Mount-Poonamallee Road. Kathipara flyover
is the largest cloverleaf flyover in the whole of Asia.
INFERENCE
 Observation of the case studies strongly manifest of the
opportunities and possibilities that the disregarded leftover spaces
under the flyovers offers.
 All case studies though different in location and community
background, suggest of future activities and uses that could be
considered in designing spaces under the flyovers if conditions
permit.
 Some similarities of activities and uses were found which suggest
that in order to attract users from surrounding communities the
leftover space may need to have cafes, food stalls, leisure,
recreational activities, business and occasional weekly activities.
 However, each area have their own unique characters, therefore
activities that is distinctively unique to that area should be allowed
to expand in order to create places with identity rather than
homogenous spaces of traditional planning.
CONCLUSION
 We can increase the level of service of road by
providing flyover in urban corridors.
 To satisfy the present and fulfill future demands of
the traffic.
 For orderly movement, left turning and right turning
maneuver can be provided.
 The capacity of road (vehicles per km) can be
increased without changing road geometrics.
Contd …_
 To provide easy, fast and safe access of public
transportation service.
 To reduce the congestion of traffic in a particular
area.
 To minimize the number of accidents.
 To reduce the travel time of vehicle or road user.
 To make a clearance for people walking on the side
of the road.
