The Department of Highways is tendering PPP rest areas: 15 sites on M6 (Bang Pa-in–Nakhon Ratchasima, 2,019 million baht) and 6 on M81 (Bang Yai–Kanchanaburi, 1,363 million baht). Only PTTRM, a unit of OR, bid on M6; no one bid on M81, so its conditions will be made more attractive. Contract signing is expected around February 2027, with full opening in 2029. For a small business, this means future roadside food, fuel and retail opportunities along these routes, mainly for large operators. Nothing needs to be done now beyond watching for tenders or subcontracting offers.
