Bangkok's longest traffic tunnel, U-mong Mahaisawan, was officially opened to traffic yesterday after almost five years of construction of this four-lane and 1.5 kilometres long tunnel.
Chairing the official ceremony to open the tunnel was Bangkok governor Pol Gen Asawin Kwanmuang.
U-mong Mahaisawan runs parallel to the Somdet Phra Chao Taksin road to pass under Rama II road.
The 17-metre wide four-lane tunnel runs five meters underground and stretches 1,515 meters. The one billion baht project was first initiated in 2001 but construction started in 2011 or 10 years after due to the project transparency.
The opening of the tunnel will help to ease traffic jam at Mahaisawan intersection which was one of Bangkok's busiest traffic intersection.
