History

The Belize-Cayo Road construction started in the 1930s and was expected to be completed by 1949.^[1]

In 1931 and before, the road existed as a horse track for pack mules and was impassable by vehicles.^[2] In 1914 two bridges were constructed at Roaring Creek and at Teakettle Creek.^[3]

In 1966 the section of road from Rockville to the Belize Zoo was replaced with a straighter road slightly further north. The old road is all that's left of the Belize-Cayo Road today.

Later the road was merged with Hector Creek Road into the Western Highway, probably in the 1980s, though this is all just speculation.
