# Puerto Rico Highway 159

Puerto Rico Highway 159 (PR-159) is the main road from Morovis to Toa Alta, passing through the municipality of Corozal in Puerto Rico. This road begins in downtown Morovis, from its intersection with PR-155 and PR-6623 to its junction with PR-165 in Toa Alta. It is about 21 km (13 mi) long.

## Route description

This highway consists of one lane in each direction for most of its length between Morovis and Toa Alta. In Morovis, PR-159 travels from its intersection with PR-155 and PR-6623 in downtown to the Corozal municipal limit, crossing through Monte Llano and Unibón barrios. In Corozal, the road serves as the main access to some neighborhoods, including Padilla, Cibuco, Dos Bocas, Barrio Pueblo, downtown Corozal, Palmarejo and Abras. Through downtown Corozal, the route was replaced by PR-891, and PR-159 makes a bypass to evade the municipal center.

## History

Puerto Rico Highway 159 is part of original segments of old Roads No. 10 and No. 20 that existed 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. Road No. 10 was the highway that led from Dorado to Coamo through Toa Alta, Corozal and Orocovis, while Road No. 20 was a route from Naranjito to Ciales across Corozal and Morovis.

## Maintenance

The issue of who is responsible for the road maintenance in Morovis was argued in April 2019. Representative Guillermo Miranda Rivera accused the mayor of Morovis, Carmen Maldonado González, of not doing road maintenance on Morovis' roads, while she blamed the central government for the condition of state roads in Morovis.
