Indian Prime Minister Narendra Modi inaugurated a six-lane, 213-kilometre Delhi-Dehradun expressway on Tuesday, completing a ₹12,000-crore (approximately $1.4 billion) infrastructure project that reduces travel time between the two cities from up to six hours to around 2.5 hours. The access-controlled corridor passes through key towns in Uttar Pradesh (India's most populous state), including Baghpat, Shamli, and Saharanpur, before reaching Dehradun, the capital of the Himalayan state of Uttarakhand. The highway also connects with major national routes — including the Delhi-Mumbai and Delhi-Meerut expressways — strengthening a broader network of high-speed corridors across northern India.
