The Department of Highways (DoH) held an initial public consultation in Suphan Buri on the MR10 motorway project's Highway 32-Suphan Buri section, presenting project details and seeking feedback from stakeholders.
Organised by the department's Bureau of Survey and Design, the meeting outlined the project's background, objectives, study scope, preliminary development concepts and expected benefits. It also gathered views from government agencies, state enterprises, local authorities, the private sector and members of the public to support further engineering design and environmental impact assessment (EIA) work.
The project forms part of Intercity Motorway No 91 (MR10), planned as a third outer ring road on the western side of Greater Bangkok. It is intended to provide an alternative route for passenger and freight traffic travelling between regions without passing through the capital, helping to ease congestion and reduce logistics costs.
Designed as a high-standard controlled-access motorway, the route will support high-speed travel and freight transport while strengthening links between agricultural and industrial production areas and the national transport network.
The alignment runs roughly parallel to the Suphan Buri-Nakhon Luang-Ban Phachi railway line and continues from the MR10 section between Highway 32 and Highway 305, which has undergone detailed design work since 2025.
The DoH has appointed a consortium of consultants to conduct a 450-day study covering a feasibility review, detailed design and an EIA.
Preliminary findings indicate that parts of the route cross flood-retention areas. Elevated structures or viaducts are therefore being considered to minimise flood impacts and maintain north-south water flow.
