Southern Highway (Belize)
In Belize, the Southern Highway takes up where the Hummingbird Highway ends and runs from Dangriga to Punta Gorda. It is entirely paved, with the completion of a 10-mile segment between Golden Stream and Big Falls circa 2008–09. The Southern Highway provides important access to a number of Mayan ruins and natural areas. The ancient Mayan sites of Nim Li Punit and Lubaantun are each situated a few miles west of the highway in southern Belize. The Cockscomb Basin Wildlife Sanctuary is several miles west of the highway in south-central Belize.
In 2011, a project was initiated, and complete by 2015, to extend the Southern Highway 21.4 mi/34.5 km to Jalacte in southwestern Belize.
