## History

The entire length of PR-164 is part of the eastern section of the old Road No. 20, a highway that led from Naranjito to Ciales through Corozal and Morovis until the 1953 Puerto Rico highway renumbering, a process implemented by the Puerto Rico Department of Transportation and Public Works (Spanish: Departamento de Transportación y Obras Públicas) that increased the insular highway network to connect existing routes with different locations around Puerto Rico. Route 20 was divided into two segments: the first one, from Naranjito to Corozal, and the second one, from Corozal to Ciales. The first section corresponds to the current PR-164 from PR-167 (old Road No. 9) to PR-159 (former Road No. 10), while the second one went to Morovis through PR-159, beginning at its junction with PR-568 (old Road No. 10) in western Corozal to continue to Ciales through PR-155, PR-633 and PR-6633 until its end at PR-6685 (former Road No. 11).
