Improvements to Interchange PR-18 with PR-21

Municipality of San Juan

Overview

The PR-18/PR-21 interchange is a key element of the Island interchange system built in the late 60’s as part of the National Highway System. PR-18 is free toll roadway bounded to the north with its interchange with PR-1 and to the south with the interchange with PR-22. This roadway constitutes the main north to south transportation corridor of Puerto Rico, PR-21 (known as Eng. José (Kiko) Custodio Avenue) is part of the tertiary system to the west of PR-18 and part of the primary urban system. It runs east to west from its signalized intersection with PR-1 toward the east up to its signalized intersection with PR-20 to the west.

Project Description

The proposed project consists of the reconfiguration of the existing PR-18/PR-21 intersection and its ramps. It will require constructing two (2) new bridges and the construction and/or reconfiguration of seven (7) ramps. It will improve the accessibility and circulation of the vehicular traffic that will result from the projected economic redevelopment of the area.

Funding

The Project has an estimated construction cost of $28.1 Million. The project is submitted to the US Department of Transportation to compete for TIGER funds. Here is a copy of the request.
