The multi-modal transportation system aims to integrate the rail and highway network through the Jamurihat-Silghat axis towards North Assam, Tawang and the rest of Arunachal Pradesh. The tunnel will take off from about 9 km upstream of the existing Kaliabomara (Tezpur) road bridge and it will connect Jakhlabandha railway station on the south bank and at Dhaliabil railway station on the north bank of Brahmaputra.

The proposed tunnels will be constructed using tunnel boring machines and may take around two to two-and-a-half years to complete. This will reduce travel time between Assam and Arunachal Pradesh. Currently, there are five bridges across the Brahmaputra.
