National Tertiary Route 929, or just Route 929 (es|Ruta Nacional Terciaria 929, or Spanish; Castilian: Ruta 929) is a National Road Route of Costa Rica, located in the Guanacaste province.[1] It is a road in the Nicoya Peninsula, it starts at Route 906 and ends at Puerto Humo, on the shores of Tempisque river.
Currently a gravel road, this is a small road that connects Route 150 through Route 906 to the Tempisque river. Together with Route 906 it is known as Spanish; Castilian: Ruta de la Leche, the Milk Route. The route visits the towns of Pozo de Agua, Puerto Humo and the Tempisque river.[2] In Guanacaste province the route covers Nicoya canton (San Antonio district).
In late 2019 a pilot program with a new and cheaper asphalt paving procedure, using recycled materials, was put in place with initial tests over this gravel road.[3] [4]
