Phahon Yothin traffic police will start a trial closure of the Ratchayothin intersection flyover between Nov 22-25 to make way for construction of the Green Line electric railway.
Police in the area will reroute traffic at the intersection to ease any congestion caused by the closure.
Pongsawat Seamsak, deputy superintendent of Phahon Yothin police, said the road closure was pushed back from its original date of Nov 16.
Motorists who use Ratchadaphisek Road and Phahon Yothin Road will be affected by the closure and can expect heavy congestion during the trial period, the officer admitted.
As a result, police have launched a traffic management plan which states:
Drivers on Rachadaphisek Road heading into Vibhavadi Rangsit Road will not be allowed to turn right at Ratchayothin intersection to go to Phahon Yothin Road. They are required to make a U-turn under the Ratchawipha Interchange and then turn left to Phahon Yothin Road.
In the evening, drivers from Ratchawipha Interchange heading to Ratchayothin intersection will not be allowed to turn right to use Phahon Yothin Road. They have to make a U-turn in front of the Shell petrol station located between Ratchadaphisek Soi 38 and Soi 40.
In the morning, drivers heading into the city using Phahon Yothin Road will be able to turn right by Siam Commercial Bank’s headquarters to use Ratchadaphisek Road. But in the evening, they are prohibited from doing so and will have to turn left to make a U-turn in front of the Shell petrol station on Ratchadaphisek Road and then turn left onto Phahon Yothin Road.
In the morning, drivers from Lat Phrao intersection who use the outbound Phahon Yothin Road will not be allowed to go straight, passing the Ratchayothin intersection. They will have to turn left to make a U-turn under Ratchawipha Interchange instead.
Pol Lt Col Pongsawat said if the traffic plan is approved, project contractors will erect signs with directions for drivers.
A source from the Mass Rapid Transit Authority of Thailand said demolition of the Ratchayothin flyover would start this month.
