The Sadao Border Checkpoint, Thailand's busiest land crossing between Songkhla and Malaysia's Bukit Kayu Hitam, is upgrading infrastructure and services to handle over 6 million annual travellers. New facilities include modernized CIQ terminals, expanded cargo logistics, and X-ray scanners. Provincial authorities plan to build a connector road to nearby communities and improve safety measures. This infrastructure push targets growth in cross-border trade and tourism in the lower south region, though execution timelines and budget allocation remain subject to Senate oversight.
