Construcción de la PR 158 - Cayey


From PR-743 to PR-1

Municipality of Cayey


The towns of Cayey, Cidra, Comerio, Aibonito and Barranquitas represent the southeastern-central region of the island with an estimated population of 165,527, according to the 2000 census, being the Autonomous Municipality of Cayey (AMC) the economic center of them. After the construction of highway PR-52, in the decade of the 70’s, this region initially experienced an accelerated growth. In the last decade, due to the increase in the cost of housing in the metropolitan area of San Juan, young professionals and other members of the labor force opted for living in the region and commuting to their place of work through the existing highway network.

The proximity of the AMC to the highway PR-52 has transformed it as an important industrial, commercial, and residential area, where thousands of workers arrive daily. There also resides the third largest campus of the University of Puerto Rico, where thousands of students and employees commute daily from the neighboring municipalities of the region. This flow of vehicles toward the AMC and out of the region of Cayey to other destinations imposes an extraordinary demand for better access highways. Figure bellow illustrates major activity centers of the area.

Proposed Improvements to the Intersection between PR-18/PR-21

As per the year 2000 Census, the labor force of this region was comprised of 41,702 persons, which for the year 2005 were projected to grow to 48,344 employed, considering an annual growth rate of 3.0%. The number of vehicles resulting from this labor force that commutes outside the region through the highway network is equivalent to approximately 24,172 vehicles per day, which added to the AADT of 16,000 for highway PR-1, represent a total daily traffic volume of 40,172 vehicles that enter and exit the region through the only two access points to highway PR-52 which are found at km. 32.3 and 38.5. This volume of traffic maintains an almost constant congestion in the urban area of Cayey, while at the same time affecting the quality of life of the residents, workers and visitors due to air and noise pollution resulting from such a high volume of traffic.

The large number of people that visit the AMC, the high volume of traffic, the rapid proliferation of businesses, commercial and industrial establishments, have all contributed to a significant deterioration of the quality of life, property value, and the social, historical, economical, and traditional setting of the municipality and the surrounding areas. High and congested traffic conditions observed in the principal intersections of the area; result in unacceptable levels of service. These conditions further result in long delays and travel times along these intersections for the users of PR-1.

Project Description

The project consists of the construction of a new roadway with an extension of approximately 1,730 meters, from roadway PR-1, at kilometer 52.3, to roadway PR-743, at kilometer 0.8. A typical section of the project consists of four lanes, two (2) in each direction with a width of 3.65 meter each, 3.00 meters wide planting strip, bicycle lane and sidewalk area to the south, and a median of approximately 4.00 meters wide. Major elements of the project are: at grade intersection of the new PR-158 with state road PR-743, Interchange with PR-52 at kilometer 35.4 and interchange with PR-1.


The Project has an estimated construction cost of $33.074 Million. The project is submitted to the US Department of Transportation to compete for TIGER funds. Here is a copy of the request.
