Bangkok’s Metropolitan Electricity Authority is to open bidding for the construction of a tunnel ahead of taking all the power cables underground in Ratchadapisek Road next year.
MEA assistant governor Thitaraksa said on Monday that the MEA had finished designing the tunnel and the project would be divided into two phases.
The first phase, a 14.3-kilometre tunnel from the Ratchadapisek-Lad Phrao Intersection to Rama IX Road, will be built with a budget of Bt4.3 billion and the bidding would be opened next year.
The second phrase, a 8.2 km of tunnel from Rama IX to the Intersection at Klongtoey will be built with a budget of Bt4.5 billion and bidding will be held in 2019.
Thepsak said the second phase would be more difficult because the MEA would have to be careful not to affect the structure of the subway under the road.
He said the MEA’s goal is to move all Bangkok’s power cables underground, a total distance of 214.6 kms, by 2021.
