State Route 4 Wagon Trail Realignment, Phase 1 Project

This project will reconstruct approximately three miles of State Route 4 in Calaveras County, east of Copperopolis, CA, by modifying the roadway’s existing horizontal and vertical curves, widening the shoulders, and adding turnouts. The purpose of these improvements is to reduce the number and severity of collisions along this stretch of roadway. The existing two-lane conventional highway will be replaced with a two-lane access-controlled expressway. The project includes approximately 328,000 cubic yards of roadways excavation, 74,000 cubic yards of rock excavation, asphalt concrete dike, guardrail, drainage improvements, creek realignment, fencing, signing, and pavement delineation.
