As part of ADB’s support for regional economic integration, transport has a critical role to play in enabling growth in trade. ADB has already provided substantial lending for constructing regional road infrastructure and has a large pipeline of planned lending operations. ADB support for transport and trade facilitation led to significant savings in vehicle operating costs and travel time, and reduced border-crossing times; and also to expansion of economic activities, with new industries and special industrial zones developing along the regional road corridors.
