Source-derived summary

Highway 302 is a national highway in greater Bangkok, Thailand. It includes two connecting roads: Rattanathibet Road and Ngam Wong Wan Road.

Route 302 is 17.808 kilometres (11.065 mi) long, of which 15.12 kilometres (9.40 mi) is in Nonthaburi, and 2.688 kilometres (1.670 mi) is in Bangkok.

Rattanathibet Road

Rattanathibet Road (Thai: ถนนรัตนาธิเบศร์) starts at Kanchanaphisek Road (Motorway Route 9) and Motorway Route 81 (Bang Yai-Kanchanaburi) 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 and Phra Nang Klao Parallel 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

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.

Editorial summary

“Highway 302 (Thailand)” enters the record as road in Thailand. Crown Archives preserves that source wording while asking what Highway, Thailand and road can confirm, complicate or overturn.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 283-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1985. Its strongest next move is a source search built around Highway, Thailand and road.
Editorial analysis

Why this record matters

“Highway 302 (Thailand)” is worth following because a concise public description often conceals a longer documentary argument. Here, Highway, Thailand and road provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q6578646. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
