Route 7 is a modern multi lane highway originating at the Sirat expressway (toll road) in Bangkok. It heads east past the Suvarnabhumi Airport in Ban Phli district, Samut Prakan province then turns southeast through Chachoengsao province then into Chonburi province where it terminates in Nong Prue outside Pattaya City. Route 7 was designed to relieve the pressure on the highly congested Sukhumvit Road (Route 3).
