The most significant entry bridge to Nakhon Ratchasima in the Muak Lek area is the "Muak Lek-Pak Chong Suspension Bridge", a pedestrian bridge spanning the Muak Lek stream within the arboretum that serves as the natural border between Saraburi and Nakhon Ratchasima provinces. Another engineering landmark is the highest elevated railway bridge in Thailand, part of the double-track railway project designed to traverse the basin-like valley and swiftly connect the central region to the Northeast. Additionally, the elevated bridges of the M6 Motorway (Bang Pa-in-Korat) offer a scenic route over the Lam Takhong reservoir and the Dong Phaya Yen forest, making the journey from Saraburi to the gateway of Isan significantly more convenient and faster than ever before.
