Munger Road Bridges #1005 and #2001

The Ada County Highway District (ACHD) is soliciting bids for the Munger Road Bridges #1005 and #2001 project located in Star, Idaho, involving comprehensive infrastructure improvements. The project requires replacing two existing culvert bridges with box culverts, including associated roadway reconstruction, utility relocations, and infrastructure enhancements. Specific deliverables include installing 16-foot span box culverts, headwalls, wing walls, riprap, curb and gutter, sidewalks, pedestrian ramps, valley gutters, irrigation pipe work, and expanding a stormwater drainage basin. Contractors must be licensed public works contractors in Idaho with a Type 1, 2, or 4 License and demonstrate capability to perform complex civil engineering and construction work. The bid will be opened electronically on October 8, 2025, at 3:00 PM, with a project completion deadline of March 15, 2026, for irrigation and bridge work and June 24, 2026, for all remaining work. ACHD intends to issue a Notice to Proceed on or about November 21, 2025, and will require comprehensive documentation including environmental compliance, utility coordination, and stormwater pollution prevention plans.

The procurement includes specific workforce requirements mandating 95% Idaho resident workers and anticipates a contract bonding requirement of $2,250,000. Liquidated damages are established at $4,000 per calendar day of delay, with a 5% retainage held on partial payments until final inspection and acceptance. While no specific set-aside designations for disadvantaged enterprises are explicitly mentioned, the project will require extensive coordination with multiple utility companies including Sparklight, Lumen, Star Sewer and Water, Idaho Power, Intermountain Gas, and Syringa Networks. The total project budget is not definitively stated, but individual bridge replacement cost estimates range from approximately $559,695 to $721,068. Bidders must submit all proposals electronically through ACHD's eProcurement portal, with manual or paper bids being deemed non-responsive. The project will be funded through local government sources and requires comprehensive environmental and engineering compliance, including Section 404 Nationwide Permit and Section 401 Water Quality Certification.
