Route 71 Improvement Project

Our subsidiary, OHLA USA, Inc., is performing an $86 million contract for a repeat client, Caltrans. This assignment will upgrade almost two miles of Route 71 from a highway to a freeway by adding one additional lane in each direction and removing all intersections, allowing for unhindered traffic flow between Los Angeles and San Bernardino Counties. Construction of an auxiliary lane on southbound 71 is also part of the contract.

The scope of work calls for earthwork and grading to make way for the additional lanes. The project team will place concrete pavement and median barriers, construct retaining walls, install new drainage systems and sound walls, and perform electrical work on almost two miles of the existing right of way. Major contract features also include replacing culverts, adding new signage, landscaping, re-alignment of on/off ramps at Rio Rancho Road, and placement of hot mix asphalt on the new freeway ramps run east and west off Route 71 in the cities of Chino Hills and Pomona.
