The Transport Ministry plans to build two new elevated tollways, Pathum Thani-Ayutthaya and Nonthaburi-western Bangkok, at an estimated total cost of 87 billion baht.
Transport Minister Suriya Juangroongruangkit said on Monday that one project would be a northbound extension of the Don Muang tollway from the Rangsit area in Pathum Thani to Bang Pa-in district in Ayutthaya.
The new elevated tollway would cost an estimated 31.28 billion baht and be 22 kilometres long. The private sector will be invited to bid for the construction of the new tollway and its operation, and the state will repay the cost later.
Meanwhile, the other project is for an elevated 35.85-kilometre tollway above the existing western outer ring road of Bangkok, between Bang Khunthian district and Bang Bua Thong district of Nonthaburi. Construction costs were estimated at 56.03 billion baht. The roads are expected to open in 2028.
