The Asian Highway Route 3 is a strategic route linking Thailand to PR China via Lao PDR. Of the entire 228 km section in Lao PDR, the existing route is mainly unpaved and running through rolling and mountainous terrain. The project is now underway to upgrade engineering standard as well as surface pavement to make it an all weather road condition. The Government of Laos PDR had sought funding for this highway section from three different sources; the Government of Thailand contributes the loan for the first 85 kilometres; the Asian Development Bank for the next 74 kilometres and the Government of PR China for the last 69 kilometres. While design and construction works for the three packages were separately carried out, ADB has given responsibility for the Project Coordination Consultant to coordinate the design and construction monitoring to ensure consistency. The road safety audit work is part of this responsibility. The paper looks into challenges in conducting road safety audit of the detailed design carried out by three different designers and report on interesting issues and lessons learned.
