Kathmandu–Terai Expressway

Kathmandu–Terai/Madhesh Expressway or NH33 (previously: H20) (काठमाडौँ तराई द्रुतमार्ग), also known as Fast Track, is an under construction road connecting Kathmandu and Nijgadh in southern Terai region of Nepal. The road is 70.977 km long, of which, 48.037 km is normal roads, 12.885 km is bridges and 10.055 km is tunnels. The expressway is being constructed by Nepal Army, originally scheduled to be completed by September 2021. The new set target date for completion is 2026. As of June 2024, around 30% of the work has been completed.

The consulting service for the construction is provided by Yooshin Engineering, a Korean firm. The most complicated section, including the tunnels and several bridges will be constructed by Chinese companies China State Construction Engineering and Poly Changda Engineering.

Controversies
In 2020, the Nepal Army had selected six international firms to provide consultation service for the project, however the process was stopped after a probe found that the selection criteria were leaked.
