Print ThisEmail This

Firestone, Colo. (Mar. 22, 2012) - Two Flatiron projects have earned Excellence in Partnering awards and four have earned Gold Partnering Success in Motion Awards from the California Department of Transportation. Flatiron's Interstate 15 Managed Lanes, South Segment, Unit 1 project in San Diego and the Interstate 5 Gateway Project in Buena Park, a joint venture with Balfour Beatty, received Caltrans Excellence in Partnering awards. Flatiron's State Route 10 High Occupancy Vehicle lanes project in Baldwin Park, State Route 110 Auxiliary Lanes project in Los Angeles and State Route 5 Sheldon Street project, also in Los Angeles, were each awarded a Gold Partnering Success in Motion award from Caltrans District 7. The Big Bear Bridge project in the San Bernardino Mountains also received a Gold award from Caltrans District 8.

The annual Caltrans partnering awards program recognizes projects where owner and contractor work together to successfully implement partnering best-practices. The Excellence in Partnering Awards are part of a statewide Caltrans program for completed projects. The annual Excellence in Partnering award ceremony will be held on May 9 in Sacramento. Individual Caltrans districts will recognize Partnering Success in Motion Award winners at upcoming district meetings.

I-15 Managed Lanes, Unit 1 South
The $80 million I-15 Managed Lanes, South Segment, Unit 1 project is one of three segments along the 20-mile section of new High Occupancy Toll lanes stretching from State Route 163 north to State Route 78 along I-15 in San Diego. In all, Flatiron is responsible for the construction of eight managed lanes contracts, totaling approximately $420 million, along the entire route. Flatiron constructed managed lanes within the existing median that provide direct access for buses via dedicated on and off ramps. Additionally, highway authorities can manage lanes by using a moveable median barrier to change the number of lanes in each direction, depending on the flow of traffic.

I-5 Gateway
Flatiron reconstructed a two-mile portion of I-5 from Orangethorpe to Artesia Avenue in Buena Park. The $193 million project, the third largest highway construction contract in Caltrans history, is comprised of six bridge improvements (both widening and complete reconstruction), three miles of retaining walls and a storm water pumping plant. The project, a joint venture with BBDI, previously earned a Caltrans Partnering Success in Motion Award in 2008.

I-10 HOV Lanes
Flatiron is constructing HOV lanes along I-10 east of Los Angeles in Baldwin Park, Calif. The $79 million contract involves construction of a new three-mile section of carpool lanes from the I-10/605 Interchange west to Puente Avenue. Construction began in 2009, and completion is expected in October 2012. The project won a Caltrans Excellence in Partnering Gold Award in 2011 from District 7.

I-110 Auxiliary Lanes
Flatiron is also constructing new auxiliary lanes and ramps on I-110 in downtown Los Angeles. Work on the $19 million contract began in March 2010, and construction will be complete in March 2013. The project won a Caltrans Excellence in Partnering Silver Award from District 7 last year.

I-5 HOV Lanes
Flatiron's $109 million I-5 Sheldon Street Project includes the construction of new HOV lanes along I-5 and two new connector bridges from State Route 170 to I-5 north. This stretch of the I-5 corridor, one of the most congested freeways in Southern California, connects major employment centers in Santa Clarita and the San Fernando Valley with the greater Los Angeles area. Crews are constructing seven miles of new bus and carpool lanes between State Route 118 and State Route 170. The project began in 2010, and its completion date is set for June 2014.

Big Bear Bridge
The $34 million Big Bear Bridge Replacement project along State Route 18 is located in the San Bernardino Mountains and replaces a structure built in 1925 that spanned the Big Bear Valley Dam. The new 475-foot-long concrete arch bridge has three 12-foot travel lanes, 10-foot shoulders and a five-foot Americans with Disabilities Act-compliant sidewalk. The new bridge ensures year-round access to communities in the Big Bear area by providing much-needed standard lanes and shoulders, and it preserves and highlights the natural and cultural resources around the dam. Construction on the project began in early 2009, and the bridge was opened to traffic in October 2011.
