The flyover at Dahitiraha will measure about half a kilometre and has been budgeted at Rs 450 million (mn), which corresponds to Rs 45 crore. The design includes an underpass to allow local traffic to pass beneath the highway and hence reduce surface congestion. The Nawabganj flyover will extend for 800 metres and carries an estimated cost of Rs 600 million (mn), equivalent to Rs 60 crore. Both structures are intended to streamline long distance traffic and lower the risk of collisions at crossing points.
Two foot-over bridges at Chamaroli and Tribhuvan Kheda have been combined in cost planning at about Rs 150 million (mn), or Rs 15 crore, and will improve pedestrian safety. A dedicated service road near Asha Khera has been allocated roughly Rs 200 million (mn), equal to Rs 20 crore, and will be built on both sides of the highway. The service road will run for 300 metres on each side and will be accessible via an underpass to allow safe crossing. This element of the project is expected to directly benefit 50,000 villagers by removing the need to cross the main carriageway.
The highway currently handles between 28,000 and 32,000 vehicles per day and authorities expect the new structures to ease peak time flow. Officials project that smoother traffic patterns will reduce travel times and lower incident rates on this stretch. Construction scheduling will seek to minimise disruption to commuters and long distance freight movements. Implementation timelines and tendering details will be released as the works move to the procurement stage.
