SR-4 Crosstown Viaduct

Malcolm Drilling Enhances Stockton’s Infrastructure with SR-4 Crosstown Viaduct Project

The SR-4 Crosstown Viaduct project is an extension of the existing SR-4 freeway between I-5 and SR-99 in Stockton. The new 2,855-foot long viaduct provides an elevated roadway that connects I-5 to Navy Drive and the Port of Stockton, significantly reducing heavy truck traffic through the Boggs Tract residential neighborhood.

Malcolm Drilling Company, Inc. was awarded the contract for the installation of CIDH concrete piles, ranging from 6-foot to 9-foot diameter and up to 150 feet deep.
