The Brown Line monorail from Khae Rai to Lam Sali, with an accompanying highway, has been approved by the Mass Rapid Transit Authority (MRTA).
MRTA Governor Pakapong Sirikantaramas made the announcement after a meeting of the MRTA Board of Directors which also discussed the source of funding for the construction of the monorail foundation.
The finance ministry is responsible for finding suitable sources of finance, including loans, for construction, he said.
The Brown Line will be built at the same time as the northern section of the expressway parallel to it by the Highway Authority of Thailand.
The MRTA will submit the Brown Line project to the finance ministry and cabinet respectively for approval, the governor said.
The Brown Line and Highway projects will hold the tender process in October to select a concessionaire to build both projects.
Using the same concessionaire for both projects would help reduce construction costs and shorten the construction period.
Building both simultaneously would also help reduce traffic problems during the construction period and minimize impacts on the public, the MRTA governor said.
The Khae Rai-Lam Sali Brown Line monorail will be on an elevated track and will have a total of 20 stations spanning 22.1 kilometers. It will be over the highway along Prasert Manukitch Road for 7.2 km.
The monorail will cost around 50 billion baht and the highway 25 billion baht.
It will be the first monorail in the Prasert Manukitch region, a growing residential area with few bus lines.
