Highway Safety Enhancements Puerto Rico Tollroad 22

Puerto Rico Tollroad 22 (PR-22) is the principal highway connecting the Metropolitan Area of San Juan with the Municipality of Arecibo, on the West coast of Puerto Rico.  PR-22 became the first freeway in Puerto Rico to enter into a Public-Private Partnership (PPP) when the Puerto Rico Highway and Transportation Authority (PRHTA) entered into a concession agreement with Autopistas Metropolitanas, LLC (Metropistas) in 2011. As part of this agreement, Metropistas must “operate, rehabilitate, conserve, and improve” PR-22’s infrastructure conditions.  As Consultants under contract with Metropistas, KEPSC was selected to analyze existing conditions, provide recommendations, and design improvements to pavement markings on four (4) segments of PR-22, which traverse the municipalities of Guaynabo, Bayamón, Toa Baja, Dorado, Vega Alta, Manatí, Barceloneta, Arecibo, and Hatillo. KEPSC’s expertise in transportation engineering brought valuable improvements to PR-22’s pavement markings including standardized acceleration and deceleration lane designs, improved weaving segments, improved design of gore areas and incorporation of state-of-the-art practices, such as raised pavement markers and longitudinal barrier delineators. In total, KEPSC contributed to the improvement and rehabilitation of 40.9 kilometers of pavement markings along PR-22.
