HEAVY CIVIL $15 MILLION - $40 MILLION


WINNER


River Bridge Hinge and Diaphragm Repairs” Te San Gabriel River Bridge Hinge and Diaphragm Repair project was needed to increase public safety and extend the life of a critical but aging bridge on a busy stretch of the I-210, which averages over 250,000 vehicles each day. Te project was the first in the history of Caltrans District 7 to require two 126-hour closures for the completion of major work. Tese closures were needed to meet tight execution timelines and relied heavily on extensive traffic flow planning and complex maintenance of traffic plans to be successful. As general contractor, Flatiron reevaluated the original traffic flow plans


and made improvements for better traffic movement, enabling the team to make quick adjustments to traffic handling in the field to meet the needs of the local cities. Working in partnership with the owner and other stakehold- ers, Flatiron delivered the project 16 working days ahead of schedule and completed all contractual items within budget and with zero claims. Also selected as finalist in this category was Teichert Construction for “Highway 20 Browns Valley Curve Correction.”
