The Outer Ring Road (ORR) Metro line in Bengaluru, from Central Silk Board to KR Puram, is set to progress quickly after a significant obstacle was removed, allowing construction to move forward.

The Outer Ring Road metro line will stretch for 19.45 kilometres up to the Baiyappanahalli Depot. The operating length of the line is 17.13 kilometres.

The ORR Metro project is encountering a significant obstruction at Doddanekundi, where the installation of an open web girder is required, spanning 65 metres across the railway line. 

Despite the railways' request for an 85-metre length to accommodate a future fifth railway track, Bangalore Metro Rail Corporation Limited (BMRCL) is disinclined to widen the structure due to space restrictions. As a result, the ORR Metro project is contending with the challenge of balancing railway interests with spatial constraints.

Construction works were delayed for over six months due to numerous discussions and negotiations between the metro and railway authorities.

Metro construction at Doddanekundi underpass will resume soon, as per a Times Now report.

Thirteen stations are planned for the 19 km Outer Ring Road line that will run from Central Silk Board to KR Puram and be operational by 2025-26.

Need For Outer Ring Road Metro Line

After the development of Electronic City and Whitefield of Bengaluru, there has been phenomenal growth of IT industry on the ORR between Central Silk Board and KR Puram. 

With these, road traffic on this road has become unmanageable though it consists of six-lane main carriageway and service roads. Phase-1 and Phase-2 of BMRCL passes at the extremities of this corridor and connecting these two important junctions is not only necessary but also inevitable.

Another important development is the Bengaluru Metro's KR Puram-KIA line achieved a breakthrough by launching the first two sets of U-girders near Chikkajala. The 784 U-girders in package 3 will construct the 15.1 km connecting Indian Air Force Yelahanka to the KIA terminal.

Each girder is 28 metres long. The opening set was finished by 5 am on 14 April. Because of the previous set's experience, the second set was completed 90 minutes early. It was completed by 4 am on 16 April .

Cranes lift the girder, which weighs 165 tonnes. Each girder is hauled by trailer from the Doddajala yard where it is cast. The stretch is on track to meet the deadline.
