The document discusses a presentation about famous truss bridges around the world. It provides details on 11 truss bridges, including the Sydney Harbour Bridge, Ikutsuki Bridge in Japan, Dashengguan Bridge in China, and the Francis Scott Key Bridge in Baltimore. It then concludes by reflecting on how civil engineers collaboratively work to enhance life through infrastructure projects like bridges.

3. An infrastructure is a basic physical and organizational
structure that assists the progress of the operation of a
society or enterprise.Bridges are indispensable
infrastructures in the worlds cities and towns where
either waterways or land barriers prevents traffic
movements to the othe side , introducing significant
impact over that regions economics , politics ,culture ,
communication as well as national defence. Amoung
many other type of bridges,truss is a well known
bridge as it amalgamates multiple triangles to support
humangous loads.
They are widely used and are most common with road
traffic bridges due to their heavy load capabilities on
the other hand the actual roadway can be directly
placed on top in case of a truss bridge , which helps to
make it easily integrated into the construction process.
These types of bridges can be built across small or
long spans while maintaining their strength. the
momentous fact is that truss bridges are economical.

Previously, the only option to
travel off Ikitsuki was by ferry to
various ports in Kyūshū.

7. The Dashengguan Yangtze River Bridge:
Traditional Chinese bridge.
Crosses the Yangtze River in Nanjing, Jiangsu.
Construction of the bridge started in 2006 and it
was completed in 2010.
The bridge has two main spans of 336 m
(1,102 ft) it is one of the largest arch bridges in
the world.
It carries six tracks: two for the Beijing–
Shanghai High-Speed Railway. (opened on 30
June 2011).
Two for the Shanghai–Wuhan–Chengdu high-
speed railway (opened on 22 January 2011) and
two for line S3 of the Nanjing Metro (opened on
6 December 2017).

8. The Francis Scott Key Bridge:
Also known originally as the Outer
Harbor Crossing (until renamed for
FSK in 1977) or simply as the Key
Bridge or Beltway Bridge, is
a steel arch-shaped continuous
through truss bridge spanning the
lower Patapsco River and
outer Baltimore Harbor /
Port in Baltimore, Maryland, United
States.
The main span of 1,200 feet (366 m)
is the third longest span of any
continuous truss in the world. It is
also the longest bridge in the
Baltimore metropolitan area.

9. Kuronoseto Bridge:
Bridge details Bridge name
japanese Span : 300m
Length: 502m(1,647ft)
Opened: 1974 Location :
kagoshima.
Kuronoseto is a strait between
the city of Akune and the
of Nagashima. The tide there
flows rapidly, sometimes
reaching a speed of 8 knots.
You can observe massive
whirlpools from the Uzushio
Observation Deck during a
spring tide.

10. The Taylor–Southgate Bridge
is a continuous truss bridge that
was built in 1995. It has a main
span of 850 feet (260 m), and a
total span of 1,850 feet (560 m).
The bridge carries U.S. Route
27 across the Ohio River,
connecting Newport,
Kentucky and Cincinnati, Ohio.
Some regard this bridge, which was
a replacement for the Cincinnati-
Newport Bridge built by Samuel
Bigstaff,[2] as a little too plain in its
design for a major urban bridge,
especially considering many cities
today are opting for a more elegant
design, such as a cable stayed
bridge.

11. Braga bridge:
With a total span of
5,780 feet (1,760 m),
and standing 135 feet
(41 m) over high water
in the Taunton River,
the Braga Bridge easily
accommodates the
high-traffic shipping
lane in the river. It is
approximately 101 feet
(31 m) wide, enough
six lanes of traffic.

12. The Julien Dubuque bridge
is continuous steel-arched bridge
that carries US 20 over the
Mississippi River connecting
Dubuque, Iowa and East
Illinois. It was constructed in the
early 1940’s in part, to help
facilitate military transportation.
The bridge has an 845 foot main
arch span with solid I-shaped steel
deck hangers. This project
performing routine biennial
fracture critical inspection of the
truss members and deck hangers.
Rope access was used to gain
hands-on access to inspect the
bridge.

13. Yoshima Bridge-
Bridge Type：
Truss bridge with two and three
continuous spans
Ground Breaking Ceremony：
October 10, 1978
Commenced on-Site Construction：
December 15, 1983
Opened to Traffic：
April 10, 1988
Yoshima Bridge is a truss bridge
which connects
Wasa Island and Yoshima Island.
The scale of the
Bridge is beyond the example in
the world as the
bridge for highway and railway.

14. The Howrah Bridge is a
balanced cantilever bridge over
the Hooghly River in West Bengal,
India. Commissioned in
1943,[9][11] the bridge was originally
named the New Howrah Bridge,
because it replaced a pontoon
bridge at the same location linking
the two cities
of Howrah and Kolkata (Calcutta).
On 14 June 1965, it was
renamed Rabindra Setu after the
great Bengali poet Rabindranath
Tagore, who was the first Indian
and Asian Nobel laureate.[11] It is
still popularly known as the Howrah
Bridge.
The bridge is one of four on
the Hooghly River and is a famous
symbol of Kolkata and West
Bengal.

15. The George Clinton Kingston–
Rhinecliff Bridge is a continuous
under-deck truss toll bridge
that carries NY 199 across the
Hudson River in New York State
north of the City of Kingston
and the hamlet of Rhinecliff. It
was opened to traffic on
February 2, 1957 as a two-lane
(one in each direction) bridge,
although it was not actually
complete. The formal opening
was May 11, 1957. The original
cost was $17.5 million.[1]

18. we have just came across through some of the
masterpiece desgined by civl engineers.This is just
a simple sketch of what a civil engineer is capable
of and how they are collaborately working in
creating a fesible world and enhance the global
quality of life . Although the role of a civil engineer in
our society is recondit by average citizens, civil
engineers continue to shape the quality of life in a
punctilious manner.
