Improvements to PR-2

Improvements to PR-2 Intersections with PR-102, PR-3108, Mayaguez Terrace, PR-2R and Luis Llorens Torres St. This project consists of two consecutive viaducts elevated along the existing PR-2 alignment, including retaining walls, fill and cut slopes, paved areas, roundabouts and storm channels. The field exploration consisted of 78 SPT borings to depths from 25 to 110 ft. Routine laboratory testing was performed as well as specialized testing including consolidation and triaxial tests. Geotechnical recommendations were provided for design of deep foundations for piers and abutments and ground improvement along retaining walls and embankments.
