I-5 HOV Improvement-Segment 2

OCTA, in partnership with Caltrans District 12 and the Cities of San Clemente, Dana Point and San Juan Capistrano, has prepared two separate Plans, Specifications and Estimate (PS&E) packages to widen Interstate 5 (I-5) and construct a new High Occupancy Vehicle (HOV) lane and other related improvements in each direction of travel. The purpose of the project is to improve existing and future levels of service on I-5, while minimizing environmental and economic impacts. The overall project is defined as the “I-5 HOV Lane Extension Project” and is comprised of two separate projects: SEGMENT 2 – from south of the Avenida Vista Hermosa interchange to north of the Camino de Estrella interchange (2.5 miles), designed by AECOM. SEGMENT 3 – from north of the Camino de Estrella interchange to south of the San Juan Creek Road undercrossing (2.4 miles), designed by TRC Solutions, Inc.

CALTROP, for Segment 2, is providing construction management and inspection services including assistant resident engineering, inspection of roadway and structural elements, establishing and maintaining field offices, project controls and scheduling, office engineering and administration, materials testing, surveying, claims avoidance and resolution.
