‘Seven generations’ tunnel partially opens

THE Bangkok Metropolitan Administration will be partially opening the nicked-named “legendary tunnel of seven generations” at Mahai Sawan intersection in Thon Buri  from 5 a.m. till 10.30 p.m. starting September 30, 2016  because some final construction clearance work is still continuing, Manager.co.th said yesterday.

After being built for over five years with the contract ending on November 2, 2016, BMA decided to partially open the underpass to resolve traffic problems. Only four-wheel vehicles and not motorcycles or buses are allowed to use this tunnel during these hours from Dao Kanong to Wongwian Yai and Wongwian Yai back to Dao Kanong.

This  four-lane tunnel is 17 meters wide, 1,515 meters long and around five meters deep. Over 969 million baht has been spent on building it with Krung Thon Engineers Company being the contractor and construction having started on October 11, 2011.

However there were construction delays leading to the nick-name “legendary tunnel of seven generations.” Key problems included moving public utilities and the construction of a waterway beneath Bang Nam Chon canal which is even deeper than the underpass.
