                     Chenab Bridge, the world’s highest railway
                      bridge in Jammu and Kashmir, is almost ready, and will
                      likely open for railway operations soon. Referring to it
                      as an ‘infrastructure marvel in making’, Railways Minister
                      Piyush Goyal also shared a photo of the 476 m-long steel
                      arches of the upcoming railway bridge over the Chenab
                      River in Jammu and Kashmir's Reasi district. 
                       
                      Reportedly, Indian Railways has been constructing this
                      bridge over the Chenab River, under
                      Udhampur-Srinagar-Baramulla rail link project (USBRL).
                      Built at a height of 359 m, Chenab Bridge has always been
                      in the news as it was touted to become the world’s highest
                      railway bridge.

                      As per Deepak Kumar, Chief Public
                        Relations Officer, Northern Railway, the construction of
                        arch closure will be completed by March 2021, whereas
                        the construction of the bridge is expected to be
                        completed by year end. Reports have it that viaduct and
                        track laying work will start once the arch construction
                        is completed.

                  | Here’s all that you need
                      to know about the world’s highest bridge.  | 
                
                
                  At 359 m height above the river
                    bed, Chenab bridge will be 35 m taller than the Eiffel
                    tower.  This bridge will be 1.315 km, and will have stations
                    at both the ends.Since the bridge has been built over a deep
                    gorge, wind will pose a significant threat on the stability
                    of the bridge. To tackle this issue, modern wind tunnel
                    tests were performed in Denmark to finalise the design, and
                    make sure that the is able to withstand wind velocity up to
                    266 kmph.
                    
                      - It’s made up of steel arches, whereas
                        the mountain slopes supporting the foundations of the
                        main arch have been stabilised.
 
                      - Although touted as an engineering marvel, it has
                        missed several deadlines for completion due to inclement
                        climate, and challenging terrain in young fold mountains
                        of Himalayas.
 
                      - Built in an earthquake prone Seismic Zone IV, seismic
                        analysis has also been carried out by various IITs.
                        Reportedly, the bridge will be able to withstand
                        earthquake forces up to Seismic Zone V.
 
                      - It has also been designed to be ‘blast-proof’ in
                        consultation with Defence Research and Development
                        Organisation (DRDO).
 
                      - Reportedly, the bridge will have a lifespan of 120
                        years, and have a design speed of 100 km.
 
                     
                    Chenab Bridge, world’s highest is a part of Jammu –

                      of Indian Railways having 14 M wide dual carriageway and
                      1.2 M wide central verge.  It was launched in 2003. 
                      Design of bridge was approved in July 2012.  It is
                      constructed in one of the most complicated and isolated
                      terrains.  Biggest challenge was not to stop the flow of
                      river.  It forms a massive steel arch, the first of its
                      kind in India.  The country has no codes or design
                      guidance for such massive structures.   Based on
                      experiences drawn from similar projects worldwide, the
                      design practices for the bridge are being followed :

                     Unemployment crisis in India is increasing rapidly. The
                      GDP growth in India has started falling since the
                      beginning of last year. To add to the difficulty the
                      spread of Corona Virus related disease in 2020 had an
                      overwhelming impact on Indian economy. As many as 41 lakh
                      youths have lost jobs in the COVID-19 Pandemic situation.
                        The entire world is reeling from the COVID-19 Pandemic
                      situation caused to lockdown and quarantine as an
                      effective measure to isolate population and prevent
                      spreading of the disease.  The worst hit are the people
                      related to farming & construction sector. However long
                      period of lockdown has registered not only job loss among
                      labourers& workers but also among Engineers,
                      Management Staff, Accountants and other highly paid,
                      skilled & qualified salaried employees doing white
                      collar jobs. The job market is shrinking day by day.   
                      Thus in the economically distressed situation of the
                      country and the world at large it is expected that many
                      people has lost and shall loose employment in days to
                      come.                                 
                    An effective means to combat joblessness in the society
                      is to encourage entrepreneurship among qualified persons
                      so that they may not depend on getting jobs after
                      graduation and shall venture out to develop their own
                      business causing employment for themselves and for others.
                       As such, scope of qualified Engineers & Architects
                      are also restricted substantially. The only available
                      alternative for sustenance is to be involved in self-
                      employment. However in this unpredictable financial
                      situation it is not amenable to go for large initial
                      investment to start a business venture. Thus knowledge
                      based consultancy can be as economically viable business
                      venture for young Engineers and Architects.
