"GAIL successfully delivers the 694-km Mumbai–Nagpur gas pipeline project, integrated with the Samruddhi Mahamarg corridor."

GAIL (India) Ltd has successfully completed the Mumbai-Nagpur Natural Gas Pipeline (MNPL), a 694-kilometre trunkline constructed almost entirely within a 3-metre-wide utility corridor along Maharashtra’s Samruddhi Mahamarg expressway. The project marks India’s first major integration of a high-capacity gas pipeline into a dense transport corridor under the PM-GatiShakti framework.

Spanning 675 km of the expressway corridor, the pipeline presented unprecedented engineering and logistical challenges. While conventional pipelines typically require 20–30 metres of workspace, GAIL installed a 24-inch high-capacity gas line within the width of an average footpath, coordinating closely with expressway construction managed across multiple packages by the Maharashtra State Road Development Corporation (MSRDC).

Officials highlighted that 96% of the pipeline runs inside the three-metre-wide utility strip, a constraint that fundamentally shaped both engineering design and construction methods.

The MNPL, designed for a capacity of 16.5 million standard cubic metres per day and equipped with bi-directional flow capability, is now nearing full operational completion, bolstering the state’s gas infrastructure and supporting India’s broader energy transition goals.
