North-East India – Security and Developmental Issues

Daporijo Bridge and its significance


From UPSC perspective, the following things are important :

Prelims level: Daporijo bridge and its location

Mains level: Border disputes with China

A key bridge over the Subansiri River in Arunachal Pradesh close to the Line of Actual Control (LAC) was constructed by the Border Roads Organisation (BRO) in record 27 days.

North-East has seen the construction of a series of bridges by BRO in recent times post-Doklam standoff. Make a note of all such bridges and the corresponding rivers over which they are built.

 Daporijo Bridge

  • This Bridge is one of the two over River Subansiri which connect Daporji in North Subansiri dist. with rest of state.
  • This and the other bridge at Tamin sustaining more than 600 villages and troops strength of around 3000 personnel manning the LAC which includes disputed Areas of Asaphila and Maza.
  • All supplies, rations, constructional material and medicines pass over this bridge.
  • The new bridge now can withstand 40 tonnes of weight allowing a safe passage for heavier vehicles catering for the requirements of the Indian Army as well as future infrastructure development requirements.


  • India has speeded up the construction of critical infrastructure in its northeast in the past half a dozen years including airports, railways and roads with an eye on China that has motorable roads right up to the border.
  • Arunachal Pradesh was the scene of the 1962 India-China border conflict that ended badly for India. China on its parts claims all of the state as “Southern Tibet.”
  • Of the 3488 km long Line of Actual Control with China 1126 lies with Arunachal Pradesh alone.
  • The two countries are yet to demarcate their border with the two sides patrolling the LAC but reporting incursions by the other side since the frontier is not clearly marked.
