The PNW timber corridor

Lumber freight in our backyard

The Pacific Northwest produces a massive share of America's softwood lumber, plywood, OSB, and engineered wood. Mills run from the Idaho Panhandle through eastern Washington, the Oregon coast, and the timber valleys of western Montana. Almost all of that production moves by truck — flatbed, step deck, Conestoga, centerbeam intermodal, and walking floor — to markets across the lower 48, Canada, and Pacific Rim export gateways.

Evergreen Shippers is headquartered in Spokane, in the middle of that corridor. We broker lumber freight every business day — from Idaho Forest Group, Stimson, Hampton, Weyerhaeuser, Sierra Pacific, Roseburg, Boise Cascade, and dozens of independents — with carrier pools, mill lane familiarity, and seasonal awareness baked into the rate.

Centerbeam Intermodal

Dimensional lumber on centerbeam trailers loaded onto BNSF rail flatcars for long-distance East Coast / Midwest moves.

Chips / Hog Fuel / Bark

Walking-floor (live-floor) trailers for chips, hog fuel, sawdust, shavings, bark — pulp mill and biomass freight.

Export Drayage

High-grade lumber and panel products to Port of Tacoma / Seattle for container export to Asia.

Equipment by load type

Trailer matched to the product

48'/53' Flatbed

Dimensional lumber, panel products, tarped — the PNW lumber workhorse.

Conestoga

Finished, pre-cut, painted, or specialty lumber that can't take tarping damage or weather exposure.

Step Deck

Tall engineered wood — long glulam beams, stacked SIPs, oversized trusses — up to 10'2" load height.

Centerbeam Rail

BNSF intermodal centerbeam for long-distance dimensional lumber to East Coast / Midwest at rail economics.

Walking Floor

Bulk chips, hog fuel, sawdust, shavings, bark — live-floor trailers self-unload without tippers.

Extendable

Long glulam beams, oversized engineered wood components beyond 53' — extendable flatbed or step deck with length permits.

PNW seasonal patterns

The timber calendar

Winter (Dec–Feb)

Pass weather (Snoqualmie, Stevens, Lookout, Lolo) affects routing. Mills run year-round; transit may stretch.

Mud Season (Mar–May)

Spring thaw triggers axle-weight restrictions on logging and mill-access roads. Light loads, slower pulls.

Build Season (May–Sep)

National housing-start surge drives outbound volume. Lumber rates peak; capacity tight.

Fire Season (Jul–Oct)

Wildfire salvage opportunities; route closures from active fires. Daily route monitoring required.

Common questions

PNW lumber freight FAQ

Dimensional lumber (2x4, 2x6, 2x10, 4x), plywood, OSB, MDF, particleboard, engineered wood — I-joists, glulam beams, LVL — remanufactured products, cants, cedar, pressure-treated lumber, decking, fencing, roof trusses, wall panels, SIPs panels, and bulk wood products including chips, hog fuel, sawdust, and shavings. Forest-byproduct loads typically ride on walking-floor trailers; dimensional lumber and panel products run flatbed, step-deck, or Conestoga.

Every major PNW producer and dozens of independent mills. Idaho Forest Group (Laclede, Lewiston, Moyie Springs), Stimson Lumber (Plummer, Forest Grove, Tillamook), Hampton Lumber (Willamina, Tillamook, Banks, Warrenton), Weyerhaeuser (Longview, Aberdeen, Raymond, Bonners Ferry), Sierra Pacific (Burlington, Aberdeen, Centralia), Roseburg (Dillard, Coquille, Riddle), Boise Cascade (Kettle Falls, Elgin, La Grande, White City), Sun Mountain Lumber (Deer Lodge MT), and smaller operators across the Idaho Panhandle, eastern Washington, and western Montana.

Most dimensional lumber and panel products ride on 48' or 53' flatbed trailers, tarped if weather protection is required. Engineered wood (glulam beams, I-joists, LVL) often runs on step decks when overall load height pushes past 8'. Conestoga rolling-tarp trailers are common for finished, painted, or pre-cut lumber that can't take handling damage. Centerbeam trailers (a flatbed with a vertical center divider) are used by mills shipping dimensional lumber on rail for intermodal moves to East Coast markets.

Centerbeam trailers ride on rail flatcars between PNW mills and East Coast / Midwest distribution centers. The lumber is banded onto both sides of a vertical center beam, which provides both load stabilization and an attachment point for tarping. Centerbeam rail moves are economical for long-distance dimensional lumber freight when transit time is flexible (10–14 days door-to-door vs 4–6 days OTR), and they offload at intermodal ramps near major lumber markets in the East and Midwest.

A walking floor (or "live floor") trailer has hydraulic slats in the floor that "walk" the cargo out the back of the trailer when unloaded, without a tipper truck or end-dump. Walking floors are the standard for chips, hog fuel, sawdust, shavings, and bark — bulk wood byproducts that flow but aren't liquid. Walking floors are also used for biomass, woody fuel for pellet mills and pulp mills, and other bulk forest commodities.

PNW lumber freight has two seasonal challenges. Mud season — spring thaw, typically March through May — brings axle-weight restrictions on logging roads, mill yard access limits, and slower pickup windows. We watch state and county weight limits and re-schedule accordingly. Fire season — July through October — brings wildfire-salvage opportunities (high-volume cuts of fire-damaged timber) and route closures from active fires. We monitor InciWeb, state DOT alerts, and mill operations daily during fire season to keep loads moving.
