Bakhtiyarpur-Tajpur Bridge Revised Cost Cleared at Rs 4,572.53 Crore

Bihar’s cabinet on Tuesday approved a revised cost of Rs 4,572.53 crore for the Bakhtiyarpur-Tajpur Ganga bridge and its approach roads, and agreed to put Rs 1,834.305 crore of state money behind finishing it. This is not a new project. It is a long-running, half-built crossing that needed more money to get to the other bank. For machine owners around Patna and Samastipur, the remaining work is a concrete job, and the new money keeps that concrete train funded.

What the cabinet approved

Dainik Jagran and Prabhat Khabar both carried the decision with the same figures. Jagran reports that this is the third administrative approval for a revised cost on the project. Prabhat Khabar and 22Scope describe the Rs 1,834.305 crore as a loan from the state to the construction company. Neither desk published the split between the bridge and the approach road, or the cost at the previous approval, so the size of the increase cannot be worked out from this decision alone.

Does this change what a contractor should buy?

Mostly it changes what gets hired, and for how long. Spread over the full 50.9 km, the revised cost works out to roughly Rs 90 crore per km. That is a structures rate, not a road rate, and the crossing is the likely reason. With the remaining work described in terms of deck segments and piers, the open machine demand is in the superstructure, not in earthwork.

In April, a site review by Bihar’s Chief Secretary, as reported by Patna Press, put the remaining work at 438 deck segments, with a target of 40 segments cast a month and work up to pier P-29 due by May 2027. He also asked for more casting equipment on site. A precast segment job like that runs on a steady fleet: batching plants, transit mixers shuttling to the casting yard, gantry and crawler cranes to handle segments, and the launching girders that set them on the piers. The girders are specialist kit the contractor already owns. The yard cranes, mixers and pumps are where local owners and rental firms usually get a look in.

Whatever approach-road work remains is a different, smaller ask. It pulls pavers, rollers and short-haul tippers in bursts, the usual road construction equipment mix, but for weeks, not years. Our reading: the state stepping in with a loan means the money risk on this job has eased, which matters to anyone being paid as a sub-hirer. A stalled river bridge is where hire bills go unpaid. The usual caution applies. The Ganga sets the calendar, and river works slow sharply in the monsoon months, so plan utilisation on the dry season, not twelve months.

For contractors tracking similar work across bridge and tunnel projects, the bigger point is supply. When a crossing this size finishes, its cranes and concrete plant come back onto the Bihar hire market at once.
