Rattanathibet Road[edit]

Rattanathibet Road (Thai: ถนนรัตนาธิเบศร์) starts at Kanchanaphisek Road (Motorway Route 9) in Sao Thong Hin subdistrict, Bang Yai District, Nonthaburi, and runs east through Bang Bua Thong District, passes Bang Kruai - Sai Noi Road (Route 3215) at Bang Phlu intersection (Thai: ถนนบางกรวย - ไทรน้อย) and Mueang Nonthaburi district, passes Ratchaphruek Road (Thai: ถนนราชพฤกษ์) at Bang Rak Noi intersection and crosses the Chao Phraya River on the Phra Nang Klao Bridge, passes Nonthaburi 1 Road (Thai: ถนนนนทบุรี 1) (Route 3110) and passes Liang Mueang Nonthaburi Road and continues east until it ends at Khae Rai intersection, where it intersects with Tiwanon Road (Route 306) and the route continues as Ngam Wong Wan Road.

Ngam Wong Wan Road[edit]

Ngam Wong Wan Road (Thai: ถนนงามวงศ์วาน) continues east from Rattanathibet Road at Khae Rai intersection in Nonthaburi, crossing into Bangkok at Lak Si District, then passing through Chatuchak District, ending at Kaset intersection, where it intersects with Phahonyothin Road. Via a bypass tunnel beneath Kasetsart, the road continues as Prasoet Manukit Road (Thailand Route 351).

Ngam Wong Wan Road is named for Damrong Ngamwongwan (Thai: ดำรง งามวงศ์วาน), a Department of Highways engineer who oversaw construction of the road. It was a policy of the Plaek Phibunsongkhram government that new roads be named for their chief engineers.
