Winter Projects in Washington: Plan for Snoqualmie Pass Delays Before They Hit Your Schedule

In winter, Washington construction schedules can be impacted by mountain pass conditions—especially when snow and advisories affect travel and deliveries. WSDOT provides real-time Snoqualmie Pass updates that many project teams rely on to plan smart.

Here’s how customers and project teams can reduce weather-related downtime.

1) Build the weather buffer into your schedule

• Add lead time for deliveries crossing the Cascades

• Pre-stage critical materials when a storm window approaches

• Keep trade sequencing flexible so work can shift indoors when needed

2) Protect materials on site

Winter moisture can warp or ruin materials.

• Store drywall, trim, and flooring in dry, conditioned spaces

• Keep lumber elevated and covered with breathable protection

• Use targeted dehumidification when interior humidity climbs

3) Safety planning keeps work moving

Cold weather increases slip risk and slows setup time.

• Keep walk paths clear and well-lit

• Verify temporary heat is safe and monitored

• Make daily “start-up” checks a habit (moisture, temps, access)

4) How Landall supports predictable winter progress

Landall plans scopes and sequencing to reduce weather disruption and protect finished work—so customers don’t pay twice for avoidable damage or delays.
