Construction on Chalerm Phrakiat Road has been completed earlier than anticipated.
The Chalerm Phrakiat Road extension project, located in Nakhon Si Thammarat province, is making significant strides, with both phases of construction progressing beyond the initial plans[1][2][4].
## Current Progress
As of July 2025, **Phase 1** of the extension, approximately 5.5 kilometres in length, is more than 23% complete. Construction includes roadbed filling, structural work, three reinforced concrete bridges, drainage systems, street lighting, traffic signs, and full safety features. It features four to six traffic lanes with a median strip and connects Highway No. 408 to Rural Road No. NS.4039[1].
Meanwhile, **Phase 2**, spanning approximately 5.28 kilometres, has progressed beyond 30%. Work underway includes roadbed filling, construction of bridge piers over an irrigation canal, and a grade-separated intersection. This section is being built as a four-lane asphalt concrete road with a median, two canal bridges, and one flyover bridge. It extends from the junction with NS.4039 to km 10+780, linking with Highway No. 4013 and the existing Chalerm Phrakiat Road[1].
## Timeline
The entire project is anticipated to be finished by 2027, with both phases advancing faster than originally planned[1][3]. Both phases have surpassed their planned timelines as of July 2025[1][2][3].
## Benefits
The extension will ease inner-city traffic congestion, improve connectivity around Nakhon Si Thammarat city, and enhance transport efficiency for both local and regional traffic[1][3][4]. The improved infrastructure is expected to support long-term urban development and stimulate the local tourism economy, providing tangible benefits for residents and businesses in the region[1][4].
In summary, the Chalerm Phrakiat Road extension is making rapid progress, offering early delivery of traffic and economic improvements for Nakhon Si Thammarat. Once completed, the extension will support the province's long-term urban development and tourism economy. Over 10 kilometres of roadway are under development for the Chalerm Phrakiat Road extension in Muang district.
As the Chalerm Phrakiat Road extension progresses beyond its initial plans, the development in the transportation sector is expected to invigorate the local economy. The project, due to be completed by 2027, involves both Phase 1 and Phase 2, which have finance-intensive elements such as construction of bridges, roadbed filling, and grade-separated intersections. Once completed, this transportation infrastructure improvement will stimulate the local finance sector by fostering long-term urban development and bolstering the tourism economy.
