CEMEX has announced that CEMEX USA is supplying concrete, including specialised self-consolidating mix, along with thousands of tonnes of aggregates for the replacement of the iconic Sixth Street Viaduct – the largest bridge project in the history of Los Angeles, California.
The original 3500 ft bridge, which has served as a backdrop in several feature films, was built in 1932 as a vital transportation link across the Los Angeles River. Over the years, the structure has deteriorated, leading to several repairs and the current replacement process.
CEMEX is expected to supply approximately 34 400 m3 (45 000 yd3) of ready-mixed concrete for the Sixth Street Viaduct Replacement Project, including 4800 m3 (6300 yd3) of Evolution, the company’s range of specialised self-consolidating concrete technology that, in this instance, was tailored to fit the bridge’s design specifications and stringent standards required by CalTrans. CEMEX is also supplying fibre-reinforced concrete solutions for the structure itself and the bridge deck. When finished, the new viaduct is expected to have ten pairs of lit arches along with stairway access and bike ramps.
Concrete for the project is being supplied by CEMEX’s Los Angeles Ready Mix Plant, and CEMEX operations in nearby Victorville are providing 67 000 t of aggregates.
The total cost of the Sixth Street Viaduct Replacement Project is estimated at US$482 million, covered mainly by federal and state funding. The bridge is expected to be completed in late 2020.
CEMEX operations in California and the Western US date back more than 100 years, with some supplying building materials for memorable projects like the Golden Gate Bridge and Hoover Dam. The company is also currently supporting the construction of the Los Angeles Purple Line Subway Extension and, recently, the company finished supplying San Francisco’s tallest skyscraper, Salesforce Tower.
“The Sixth Street Viaduct is one of the memorable landmarks in Los Angeles, and CEMEX is proud to help give it a much-needed update,” said Bryan Forgey, CEMEX USA President/General Manager of Ready-Mix – Southern California. “CEMEX is deeply rooted in Southern California. Materials we produce here are building a better future for our families, neighbours, and communities.”
“CEMEX has been part of Southern California for decades, helping provide the materials that are critical in the roads, bridges, and buildings we use every day all across the state and the Southwest,” said Eric Wittmann, CEMEX USA Regional President – West Region. “We are proud to be building a better future in Southern California, providing cement, concrete, and aggregates for projects to be used by generations to come.”
