Heavy Equipment Shipping from Seattle, WA to Boise, ID

Route Overview: Seattle to Boise via I-90/I-82/I-84

The standard heavy-haul route from Seattle, WA to Boise, ID covers approximately 500 miles across three states. The route follows I-90 East from Seattle through Snoqualmie Pass (elevation 3,022 ft) to Ellensburg, then I-82 East through the Yakima Valley and Columbia River Gorge area to Hermiston, Oregon, then I-84 East through the Blue Mountains (elevation ~4,200 ft at Deadman Pass) and across the Snake River Plain into Boise. Total transit time for a loaded heavy-haul rig is typically 9–12 hours, often requiring a driver rest stop.

Mountain Passes: Snoqualmie and Deadman Pass

Snoqualmie Pass (I-90, elevation 3,022 ft): The primary challenge leaving Seattle. The pass has 6% grades on both approaches and is subject to chain requirements and closures during winter storms (November–April). WSDOT may impose oversize travel restrictions during adverse weather. The pass is generally reliable May–October.

Deadman Pass (I-84, elevation ~4,200 ft): Located in the Blue Mountains of Oregon near Pendleton, this pass has steep grades and is also subject to winter closures and chain requirements. ODOT may restrict oversize loads during winter weather events. Brake check stations are located on the descent.

Both passes require careful scheduling in winter months. IronHaul monitors WSDOT and ODOT road condition alerts and adjusts dispatch timing to avoid pass closures.

Multi-State Permit Requirements

State	Width Limit	Height Limit	Weight Limit	Permit Agency
Washington	8'6"	14'0"	80,000 lbs GVW	WSDOT Oversize/Overweight
Oregon	8'6"	14'0"	80,000 lbs GVW	ODOT Oversize Permits
Idaho	8'6"	14'0"	80,000 lbs GVW	ITD Oversize Permits

Three-state permit coordination is required for this lane. Washington and Oregon permits typically process in 1–3 business days; Idaho permits are generally available within 1–2 business days. IronHaul handles all three states simultaneously to minimize total permit processing time. Loads exceeding 14 feet in width or height may require route surveys and engineering approval in one or more states.

Common Equipment Moved on This Lane

• Excavators: Construction excavators moving between Seattle-area projects and Boise's booming residential and commercial construction market.
• Agricultural equipment: Large tractors, combines, and tillage equipment moving between Washington's agricultural regions and Idaho's farming operations.
• Crawler dozers: Mining and construction dozers moving between Pacific Northwest projects and Idaho mining operations.
• Cranes: All-terrain and rough-terrain cranes moving between Washington and Idaho construction projects.
• Compact equipment: Skid steers, compact track loaders, and telehandlers — often multiple units per load on a step-deck trailer.

Transit Times and Scheduling

At ~500 miles with two mountain passes, this lane typically requires 2 days for most oversize loads — one day of driving with a mandatory rest stop, or a split pickup/delivery schedule. Non-permit loads can sometimes be delivered in a single long day. Winter scheduling should add 1–2 days of buffer for potential pass closures. Summer (June–September) is the most reliable season for this corridor.

Cost Factors on the Seattle–Boise Lane

• Base rate: $3.50–$6.00/mile for standard oversize loads (~500 miles).
• Three-state permit costs: $150–$600 total for standard oversize permits across WA, OR, and ID.
• Pilot cars: Required for loads over 14 ft wide in all three states. Pilot car rates: $1.50–$2.50/mile per escort vehicle.
• Fuel surcharge: 15–25% of base rate.
• Winter surcharge: Some carriers add 10–15% for winter mountain-pass moves due to increased risk and potential delays.
