Traffic in Bangkok turned chaos with very heavy congestions on many roads after traffic police rearranged traffic at Ratchayothin intersection to facilitate the construction of a tunnel at the intersection.
Constructionn of the tunnel will begin 20.00 pm tonight with traffic roundabout in force for four months or until end of May.
The tunnel will replace the Ratchayothin flyover which was demolished to pave the way for the construction of the 19-kilometres long Green Line sky train extension from Morchit to Saphan Mai and Khu Khod.
Traffic roundabout was introduced at the Ratchayothin intersection for the first day today, causing confusion among motorists using the intersection who are not aware of the traffic change.
Affected by the traffic change are Phahon Yothin road from Bang Khen circle to the Kasetsat intersection and from Sena Nikhom to Ratchayothin. Traffic here was reported to move at snail pace since 6.30am, and Ratchadapisek road from Thian Ruammit intersection to Asoke Montri road was also very congested.
But most affected is Vibhavadi-Rangsit with vehicles tailing back to as far as Don Mueang air force base.
The change also affected connected roads such as Kaset Nawamin and Lard Prao. Traffic on connecting expressways was also heavy.
Traffic police advise motorists to avoid the Ratchayothin traffic roundabout if they have other choice as heavy traffic congestion is unavoidable.
