Tunnel excavation of 1860 m has been completed from portal P1 end and 1039 m completed from P2 end. Now, the balance excavation is only 260m. Due to Main boundary thrust location, the progress is very slow. Tunnel excavation requires lot of pre- support measures and also post excavation support systems.

At Katra end of this bridge, construction of MA1 abutment substructure was in progress and 9m has been cast out of 22.3m height. Project executives informed that only balance work on Katra end is 38m span of MA1 and CA2, which is under fabrication and will be launched by Dec.’2022.
Thereafter, Reasi end of Anji bridge was inspected. Sub-structure has been completed and super structure launching/erection is under way. 249m out of 473m deck has been erected which includes launching of 6 segments using Derrick (segment launcher).
