Utah Transit Authority says its will begin installing a state-of-the-art bridge foundation made of 40-foot Geofoam blocks March 19, as part of its West Valley Light Rail line construction project. An inaugural ceremony will mark use of the Geofoam blocks on the first of four bridges that are included in the project.
UTA says the Geofoam blocks fit together “like Lincoln logs”; the material, a lightweight fill and ground stabilizer, will be placed under the concrete portion of the bridge(s) and light rail track.
The authority says the use of Geofoam, a product of Denver-based ACH Foam Technologies, instead of other fill material “could save up to three years of construction time waiting for the material to settle. This saves the costs involved in extending the project timeline.”
The West Valley line, one of UTA’s several LRT extension projects will extend light rail service from the existing Sandy/Salt Lake TRAX line, adding five miles and four new station stops at an estimated cost of about $290 million. The extension is expected to draw 9,000 additional riders by 2025.
