The Pamban Bridge in India connects Pamban Island to the mainland. It has a double leaf bascule section that can be raised midway to allow ships to pass through, making it an example of a convertible bridge. Convertible bridges can be used for both road and water transport by having a movable section that opens to permit ship traffic. Proximity and motion sensors would automatically open and close the Pamban Bridge's bascule section based on detecting approaching ships or trains.

3. PAMBAN BRIDGE
 The Pamban Bridge is a railway
bridge on the Palk Strait which
connects the town of Rameswaram
on Pamban Island to mainland India.
 The railway bridge is 2,065 m long.
 It was opened on 24 February 1914.
 It has a double leaf bascule section
midway, which can be raised to let
ships and barges pass through. PAMBAN BRIDGE
 It was India's first sea bridge, and was the longest sea bridge in India
until the opening of the Bandra-Worli Sea Link in 2010.
 The length of the double leaf bascule section is 289 ft.

4. CONVERTIBLE BRIDGE
 It is a type of bridge which can be used to
move passage via bridge as well as water.
 it is generally powered by electric motors, or
hydraulic piston or gearing system.
 Sometimes, when a long bridge required, we
provide a certain amount as movable at the
mid of the bridge to allow the ships to pas
through it.

5.  Some movable bridge may be enabled by
engine some might not be, some may be
manually operated, some can be operated by
remote and some can be operated
automatically by using MOTION SENSORS.
It all depends on the length of the bridge and
location of the bridge.

6. WHY WE NEED TO CONVERTIBLE BRIDGE:
 As most of the part of our earth is covered
with water(about 70%) so we need to
develop a transportation via water too
because it can be a shortest and cheapest
way for communication among countries.

7. TYPES OF CONVERTIBLE BRIDGE
 Draw bridge
 Bascule bridge
 Folding bridge
 Rolling bridge
 Lift bridge
 Retractable bridge
 Rolling bascule bridge
 Submersible bridge
 Tilt bridge
 Swing bridge
 Transporter bridge

19. PROJECT DETAILS:
 We are working on Pamban convertiable bridge.
 We are using motion sensor and proximity sensor to
sense coming ships and trains on the track and sea
respectively.
 They are so provided in such a way that whenever a boat
or ship came into the radius of that sensor it will
automatically turn Red signal for train and the relay will
send the information to the control room from where the
person will clear the rail track and will send command for
opening the bridge. After passing of the ship the
Proximity sensor will send the information for closing the
Bridge and thus turning green signal for train and red for
ships.

21. IT WILL BE LIKE THIS:

22. PRO AND CONS:
 Main advantage is it enhance the
connectivity among cities of one country to
another at easiest manner.
 It reduces the cost of bridge which is the
main factor of proposing any bridge over a
location.
 Its main disadvantage is that all the vehicle
should be removed before opening the
bridge.
