RDC0015749 - The Old Rd over Santa Clara River and SPT CO Bridge et al Phase I

Budget estimate

$8,000,000 – $18,000,000

The project involves bridge replacement and a roadway widening segment in a high‑traffic area of Los Angeles County. Similar county bridge‑rehab/widening contracts in Southern California typically range from $5 million to $25 million depending on length, bridge type, and environmental mitigation. Assuming a moderate bridge size and a 0.5‑mile road segment, a reasonable ball‑park estimate would be between $8 million and $18 million for the full construction scope. Factors influencing the final amount include exact bridge dimensions, soil/earthwork conditions, utility relocations, and prevailing‑wage requirements.
