Guardrail Installation Contractor in Washington State | Ideal Fencing Corp

WSDOT specifies W-beam guardrail per AASHTO M-180, thrie-beam for higher deflection conditions, and high-tension cable median barrier — one of the largest cable barrier programs in the US. End terminals must appear on WSDOT's approved products list; common systems include FLEAT, ET-Plus (MASH-compliant), and SKT-SP. All hardware must meet WSDOT Standard Specifications for galvanization and section properties.

Yes. Our crews regularly work on Cascade pass routes including I-90 at Snoqualmie Pass and US-2 at Stevens Pass. We plan around WSDOT's seasonal restrictions, avalanche closures, and the limited construction windows at pass elevations, and we use equipment appropriate for steep grades and potentially frozen subgrade.

Work near streams and wetlands in the Puget Sound basin triggers Washington Department of Fish and Wildlife Hydraulic Project Approval (HPA) requirements. Our project teams coordinate HPA applications with WSDOT environmental offices and implement erosion control per the WSDOT Highway Runoff Manual before ground disturbance begins.

Yes. We serve the I-90 corridor from Ellensburg to Spokane, US-2 through the Palouse, and SR-17, SR-26, and US-195 in Eastern Washington. Basalt rock and hardpan soil conditions common east of the Cascades require rotary drill equipment — we bring the right machinery rather than relying on standard driven-post methods that fail in volcanic rock.
