Char Dham Highway Project

The Char Dham Highway Project — also called Char Dham Mahamarg Vikas Pariyojana — is the most ambitious Himalayan road infrastructure mission in Indian history. The 889 km network of all-weather two-lane highways connects the four Char Dham pilgrimage sites in Uttarakhand: Yamunotri, Gangotri, Kedarnath, and Badrinath.

The project was sanctioned in 2016 by Prime Minister Modi as a flagship of his Himalayan-state development push. The mission upgrades existing single-lane mountain roads (which were chronically blocked by landslides during monsoon and snow during winter) into stable two-lane all-weather highways suitable for both pilgrim traffic and military supply convoys to forward posts on the Indo-China border.

Execution is shared between Border Roads Organisation (BRO) — handling the higher-altitude and more strategic segments — and the National Highways & Infrastructure Development Corporation Limited (NHIDCL) — managing the contracted private packages. Total budget: ₹12,000 crore.

Key segments include: Rishikesh-Yamunotri (240 km), Rishikesh-Gangotri (260 km), Rishikesh-Kedarnath (235 km via Tilwara), and Rishikesh-Badrinath (320 km via Joshimath). The project has involved extensive slope-stabilisation engineering — addressing fragile Himalayan slopes prone to landslides — and over 30 km of tunnel works to bypass landslide-vulnerable sections.

The project has also been controversial: it was challenged in the Supreme Court on environmental grounds, with critics arguing the cumulative slope-cutting has destabilised the very mountains it traverses. The 2023 Joshimath subsidence incident reignited the debate. The Supreme Court ultimately allowed the project to continue with modified width specifications for ecological zones.
