The Expressway Authority of Thailand plans to call tenders next year for the construction of a new east-west expressway, stretching 11.3 kilometres from Kasetsart intersection to Bangkok's eastern ring road.
The new route is due to open in 2024 and run above a monorail.
Exat deputy governor Wichan Ekarintrakul said the 18-billion-baht N2 expressway project will be proposed to the Exat board and cabinet for approval. Bids for the contract will be called in late 2020, with construction to begin in July 2021. After opening, it will serve a projected 80,000 vehicles per day initially, rising to 100,000 a day, he said. The project will not require any additional land expropriation.
From Kasetsart intersection, the expressway will be built on finished pillars along Prasert Manukit Road, and will run along the Brown Line electric monorail, from Khae Rai to Lam Sali, he said.
