CEMEX supplies project to replace iconic LA bridge

First publishedon www.AggBusiness.com

The US division of building materials company CEMEX is supplying the project to replace the iconic Sixth Street Viaduct Bridge in Los Angeles, Calif.

CEMEX USA is providing concrete, including a specialised self-consolidating mix, along with thousands of tonnes of aggregates for the project.

The original 3,500-foot bridge was built in 1932 as a vital transportation link across the Los Angeles River. The structure has deteriorated over time, leading to several repairs before its closure in 2016 and the start of the current replacement process.

The bridge served as a backdrop in several feature films including Point Blank, Grease, Repo Man, Terminator 2: Judgement Day, Transformers and The Naked Gun.

CEMEX is expected to supply approximately 34,400m3 of ready-mix concrete for the Sixth Street Viaduct Replacement Project, including 4,800m3 of Evolution, CEMEXs range of specialised self-consolidating concrete technology. The Evolution technology has been tailored to fit the bridge’s design specifications and standards required by state transport department CalTrans.

CEMEX is also supplying a fibre-reinforced concrete solution for the structure itself and bridge deck. The new viaduct is expected to have ten pairs of lit arches along with stairway access and bike ramps when it is completed, which is expected to be by late 2020.

Concrete for the project is being supplied by CEMEX’s Los Angeles Ready Mix Plant, and the company’s operations in nearby Victorville are providing 67,000 tonnes of aggregates. The total cost of the project is estimated at US$482m, covered mainly by federal and state funding.

“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’re proud to be building a better future in southern California, providing cement, concrete and aggregates for projects to be used by generations to come.”
