"Bow Shaped Bridge," a new landmark bridge over the Chao Phraya River, is set to become a new landmark in Sing Buri Province

     In the not-too-distant future, Thailand will introduce a new bridge crossing the Chao Phraya River in Sing Buri Province, creatively designed as the "Bow Shaped Bridge."

     The Department of Highways has a plan to survey and design a new junction on Highway No. 311, from the City Pillar Shrine intersection to the Krai Sorn Ratchasi intersection (including the bridge crossing the Chao Phraya River) in Sing Buri Province, with the intention of improving and increasing the efficiency of traffic on Highway No. 311 and at various intersections along the route, including the City Pillar Shrine intersection, Khun San intersection, and Krai Sorn Ratchasi intersection, totaling approximately 1.5 kilometers.

     The Bow Shaped Bridge is designed to blend in with the scenic views along the Chao Phraya River. It replaces an old bridge that had been in use for a long time. The design took into consideration public participation, environmental factors, engineering, and economics. Hence, the bridge is designed as a bow-shaped structure with a network tied arc bridge system, boasting a length of 150 meters spanning across the river.

     This new bridge is designed to accommodate three traffic lanes with a width of 3.50 meters each, outside and inside shoulders are 2.50 meters wide. In the future, it can be adjusted to accommodate four traffic lanes. In addition, the design includes improvements for under-bridge passages that allow for vehicle U-turns and river navigation. Furthermore, the steel structure of the bridge is highly resistant to corrosion, reducing the budget for maintenance.

     The construction of this bridge, in addition to alleviating traffic congestion, will also increase safety for travel, enhance the efficiency of transportation, support economic and social growth in the Sing Buri Province, and can be developed into a tourist attraction. Moreover, it can become a prominent and distinctive landmark of Sing Buri Province in the future.

     The budget allocated for the construction of the bridge is 980 million baht. If the annual budget for the fiscal year 2023 is approved, the construction would take 3 years, and it is expected to be completed and opened for public use by 2026.
