What is the length of the NH-22 section in Bihar approved for four-laning?

The correct answer is Hybrid Annuity Mode, usually shortened to HAM. This is the model under which the Cabinet Committee on Economic Affairs cleared the upgradation of the 82.57-km stretch at a total capital cost of Rs 3,590.73 crore. Option A, Engineering, Procurement and Construction, places the entire cost on the government and is a common mode for highway work, but it is not the one chosen here. Option B, Build, Operate and Transfer on a toll basis, leaves the developer to recover money from users and is likewise not applicable. Option D, Build, Own, Operate and Transfer, is another concession structure used in infrastructure but not for this project. Aspirants should also remember that the work was planned under the PM GatiShakti National Master Plan, which coordinates road, rail and logistics planning.

The correct answer is Bagmati. Among the seven major bridges in the project is a 340-metre structure over the perennial Bagmati river, which the corridor must cross on its way from Muzaffarpur towards the border. Option A, the Kosi, is a well-known river of north Bihar and a frequent distractor in questions on the state's bridges, but it is not the river named here. Option B, the Gandak, flows to the west of this alignment. Option D, the Burhi Gandak, passes close to Muzaffarpur and is therefore a tempting choice, yet the bridge in question spans the Bagmati. Besides the seven major bridges, the project includes three railway overbridges and two flyovers, all meant to smooth crossings and reduce conflict between road and railway movement along the route.

The correct answer is Sonbarsa. The section being widened runs from Muzaffarpur through Sitamarhi to Sonbarsa, which sits on the India-Nepal border, and the upgraded road will feed cross-border traffic moving through the nearby Bhithamore Land Port. Option A, Raxaul, is a major Indian border town opposite Birgunj but lies on a different corridor. Option B, Jogbani, is a border crossing in the Araria area of Bihar and is not on this alignment. Option D, Birgunj, is in Nepal itself, so it cannot be the Indian end of the highway. The road also passes through Muksudpur, Runni Saidpur, Thumma, Dumra and Bhutahi, and it improves access to Baba Garibnath Temple, Mata Janki Temple, Punaura Dham and the Buddhist Circuit.

The correct answer is Sairang, 51.38 kilometres. The Bairabi-Sairang railway line of that length was called a historic milestone that placed Mizoram on the railway map of the country and changed the state’s access to major economic centres. More than 15 lakh passengers have since travelled on over 1,100 train trips that link Aizawl with Guwahati, Kolkata and Delhi, and the Sairang-Silchar service has strengthened ties with the Barak Valley. Sairang also received the first Food Corporation of India food-grain rake in March 2026, carrying about 26,000 quintals of rice from Punjab in 42 wagons. Option B mixes in the 74 circuit kilometres of the Bairabi-West Phaileng power line. Option C uses the length of the road projects at Pukzing-Silsuri and Tualpui-Champhai, and option D borrows the length of the Oil Palm Link Road.

The correct answer is Rs 331 crore. Union Minister for Communications and DoNER, Jyotiraditya M. Scindia, took up ten projects of about this value in Mizoram on 12 October 2026 in the presence of Chief Minister Pu Lalduhoma. The figure is made of two parts, and that is where the other options come from. Option A, Rs 102 crore, is only the worth of the five projects dedicated to the people, among them the Daido-Vangkawt Road in Champhai and the 132 kV Bairabi-West Phaileng transmission line. Option B, Rs 228.54 crore, is only the worth of the five projects whose foundation stones were laid, such as the Pukzing-Silsuri Road and the sports infrastructure works. Added together these two parts give the total of about Rs 331 crore, so neither part alone is the answer. Option D is not a figure connected with this visit.
