Project Details

The highway project focuses on improving the Sahebganj to Bettiah area of National Highway 139W. It’s a significant investment, costing Rs 2,160 crore. The project is being built using a special system called a ‘Hybrid Annuity Mode’. This means that the government and the company building the highway share the costs and risks.

Hybrid Annuity Mode Explained

A Hybrid Annuity Mode is a way for big infrastructure projects to get built. It combines a fixed amount of money from the government with a share of the tolls collected on the new highway. This helps to ensure the project gets completed, regardless of how many cars use it.

The work will be divided into two sections: Section 1 will run from Sahebganj to Areraj, covering 38.362 kilometers. Section 2 will extend from Areraj to Bettiah, spanning 40.580 kilometers. Both sections are being built to become a four-lane highway.

This highway expansion promises vital connectivity improvements, driving economic growth in Bihar.
