Cha-am bypass opens key intersection as part of major expansion
The long-awaited opening of a new intersection on the Cha-am bypass is set to revolutionise travel between Cha-am and Hua Hin, with the newly launched overpass marking a significant step in the ongoing development of Highway 37.
The overpass, located at the Huai Ta Paet intersection in Sampraya subdistrict, Cha-am district, opened to traffic at the end of last month, providing smoother access in both directions, northbound towards Bangkok and southbound towards Hua Hin and Pranburi.
This is just one part of a much larger infrastructure project aimed at improving road safety, alleviating congestion, and driving economic and tourism growth in the region.
The 50-kilometre expansion project, overseen by the Department of Highways, is upgrading the current four-lane road to six lanes and constructing six grade-separated interchanges, in addition to adding 17 U-turn points.
The total cost of the project is estimated at 7 billion baht, with completion scheduled for 2026. Once finished, Highway 37 will consist of three 3.5-metre-wide lanes in each direction, with a wide 10.6-metre median separating the two sides.
Concrete barriers, hard shoulders, and U-turns will also improve both safety and traffic flow along the route.
