In the past, Highway 43's origin was in Kheha Intersection when Phetkasem road goes to Rattaphum to Hat Yai (now part of Highway 406, Highway 4287 and Highway 407) and Highway 43 terminus at Khlong Wa intersection, the current kilometer zero of this route was located.

Until now, Phetkasem Road extending and bypass its old route to Khlong Wa intersection, Highway 43 extended entire route of Highway 4131 to Khuan Mit intersection and a section of Highway 408 to Paching intersection. Highway 4086 were extended to Don Yang intersection but entrance to Chana was part of the route itself and entrance to Sakom Pakbang is part of Highway 4370, making Highway 43's terminus before extending to Ban Dee Intersection, its current terminus.
