• Burapha Withi and Kanchanaphisek: April 12-18
• Si Rat, Udon Ratthaya, Chaloem Maha Nakhon: April 13-15
• Motorway No 7 (Bangkok-Chonburi-Pattaya), Motorway No 9 (Bang Pa-in–Bang Phli-Phra Pra Daeng-Bang Khunthien: April 12-18
• Motorway No 6 (Bang Pa-in–Nakhon Ratchasima) 64km from Pak Chong to Kham Thale So: April 11-17
