As per our sources, construction of the underground Patna Junction metro station has moved into the diaphragm wall stage, with D-wall grabbing under way and reinforcement cages being tied for the fourth wall panel. The Times of India reported, citing Patna Metro Rail Corporation (PMRC) officials, that the station will be an interchange between Corridor I (Danapur to Khemnichak) and Corridor II (Patna Junction to the Patliputra Inter-State Bus Terminal). It will have four entry and exit points, eight lifts and eight escalators, a concourse about 8 metres below ground, and the Corridor II platform will sit above the Corridor I platform. A subway link to Patna railway station is also planned.
This development matters because Patna Junction is the busiest point in the city, and a direct rail to metro transfer could take a large share of luggage-carrying passengers off autos and cabs on Station Road. Diaphragm walls form the outer box of an underground station, so this work sets the pace for everything that follows. Traffic diversions around Station Road and Dak Bungalow will stay for as long as the station box is open.
We believe that the D-wall start is real progress but still an early step, since only four panels are being worked on in one of the most crowded parts of Patna. Deep digging next to old buildings and a live railway station usually throws up utility shifts and ground issues that slow the job. We expect wall work to take at least until mid 2027 before main excavation of the station box is fully under way, and we see commuter use of this station before 2029 as unlikely. Confidence: medium.
This is important for our readers because the diversions near Patna Junction will affect anyone catching a train this week and in the months ahead. Leave extra time to reach the station, especially for early morning and evening trains. Check the latest traffic police advisory for Station Road and Dak Bungalow before you set out, and use the marked pedestrian routes around the barricades.
