Haldia port currently handles most of Nepal's trade, but there is no developed highway with Haldia port to the India–Nepal border. Haldia-Raxaul Expressway is proposed to be constructed with the aim of establishing better highway connectivity. The 650 km long expressway will serve the primary objective of improving freight efficiency and increasing exports from neighboring regions. History 
The National Highways Authority of India (NHAI) invited tenders in 2021 to prepare a detailed project report for an expressway connecting Raxaul in Bihar on the Indo-Nepal border with the Haldia port in West Bengal. After opening technical bids on 17 June 2021, the National Highways Authority of India announced that 13 design and engineering firms had submitted bids to prepare a detailed project report for the approximately 650 km Raxaul-Haldia Expressway.
