CRP 630 – Ironwood Bridge #636-4.87 Replacement.

The project replaces the Ironwood Road Bridge over South Columbia Basin Irrigation District’s Eltopia Branch Canal. The new bridge will be in the same general footprint with a wider driving surface to meet current standards and functional requirements, increasing from 24’ in width to 32’ in width, containing two (2) 10’ travel lanes and 6’ shoulders. The bridge length is 90 feet between pavement seats and completely spans the existing earth canal. The project also includes installing guardrail, HMA paving, and other work. The project is located 17 miles north of the City of Pasco (46.519638°, -119.149629°).
