Bangkok: The temporary opening of the Chalerm Maha Nakhon Expressway at the Dao Khanong checkpoint, inbound to Bangkok, is underway today. This initiative is aimed at alleviating the severe traffic congestion on Phra Ram 2 Road, following the collapse of structural parts in the area.
According to Thai News Agency, today marks the first trial of opening one traffic lane on the inbound side of the expressway near the site of the collapse. Initially, it was anticipated that clearing the area might take up to seven days. However, due to the relentless efforts of officials working round the clock, the route has been opened ahead of schedule. This measure is expected to help ease the traffic burden on Rama II Road significantly.
Mr. Surachet Laopoolsuk, Governor of the Expressway Authority of Thailand (EXAT), together with Pol. Maj. Gen. Thawat Wongsanga, Deputy Commissioner of the Metropolitan Police Bureau, conducted an inspection of the traffic conditions at the Dao Khanong Toll Plaza. The inspection followed the collapse of a construction bridge beam, which had caused significant traffic disruptions, necessitating temporary traffic adjustments.
Mr. Surachet disclosed that EXAT and the Traffic Police Division (T.P.D.) have coordinated efforts to open a diversion route for public use. The route is now operational and is expected to mitigate the congestion on Rama II Road. Meanwhile, the demolition of the collapsed beam debris has progressed beyond 70 percent, with officials working tirelessly. It is projected that the demolition will be fully completed within seven days. However, clearing the exit of the collapsed materials may take up to 30 days due to the complexity and size of the debris, though efforts are being made to expedite this process.
Pol. Lt. Col. Thawat Wongsanga noted that the affected route typically accommodates over 1,000 vehicles during rush hours. The newly opened lane is restricted to 4-wheel vehicles, and the public is advised to avoid the route unless necessary. The trial opening is expected to reduce traffic congestion by approximately 30 percent.
Morning traffic conditions have remained manageable, partly due to the school break, which has decreased the volume of vehicles. However, congestion is anticipated to increase after 8:00 AM. Traffic police have prepared a contingency plan to assist the public, advising them to consider alternative routes, such as Kanchanaphisek Road to Ekkachai, Petchkasem, Kanchanaphisek parallel road to Phra Pradaeng Bang Khun, and Thian Seaside Road to Bang Bon 1, Ekkachai, and Dao Khanong.
Currently, two diversion lanes, typically used by bridge construction contractors, are available. However, this route is not fully convenient for large vehicles due to ongoing construction equipment obstructing some areas. Traffic on Rama 2 Road, a primary city-bound route, is expected to worsen, especially when the school term resumes, leading to increased suburban traffic into Bangkok. From 8:30-9:00 a.m., the volume of large trucks is also expected to rise, further slowing traffic.
Commuters are advised to allocate at least one hour for travel, particularly those entering the city via this route. While the diversion route may not restore traffic flow to usual levels, it is expected to offer some relief. Officials have established a war room at the Dao Khanong checkpoint to monitor traffic in real-time. Daily meetings will be held to assess problems and devise solutions, with adjustments to routes being considered as necessary.
