I-90 · SELECTED CORRIDORS
I-90 trip weather — the segments we actually cover.
Compare arrival-time weather on 2 curated I-90 corridors, then check the official road sources for every state on your drive.
This is not an end-to-end I-90 status page. The cards below are the only I-90 trips in the current catalogue. Unsampled miles, most closures, traffic speeds and pavement observations remain outside the weather model.
I-90
~280 miSnoqualmie Pass
Seattle to Spokane
Compare the wet western approach, Snoqualmie Pass and the drier inland sections on the same timeline. Summit conditions need their own check rather than a Seattle or Spokane city forecast.

I-94 / I-90
~410 miUpper Midwest
Minneapolis to Chicago
This Upper Midwest corridor crosses Minnesota and Wisconsin before the Chicago approach. Winter road conditions, wind and visibility can vary widely over the drive, so use multiple checkpoints and all three state road sources.

OFFICIAL ROAD SOURCE HANDOFF
Check every state your selected corridor crosses.
These links are official road-information services. A link is not counted as an integrated feed.
A BETTER WAY TO USE THIS PAGE
Pick the actual corridor.
Do not use a whole-Interstate label as a proxy for a city-pair journey.
Pulse or compare departure weather.
Weather is matched to estimated checkpoint arrival, with missing data kept visible.
Finish at the official road source.
Current restrictions, incidents and road access remain separate from the weather category.
QUICK ANSWERS
What this I-90 planner means.
Does this page show all I-90 road conditions?
No. RoadAheadNow currently covers 2 selected I-90 corridors on this page. It does not claim end-to-end I-90 road-status coverage.
Can I see live weather for these I-90 trips?
Yes. Each listed corridor has an on-demand weather pulse and a full four-departure comparison using selected NWS forecast checkpoints. The weather result is not a road-open clearance.
Are closures and pavement conditions included?
Most road-status data remains an official state-authority check. Only pages that explicitly label a bounded Caltrans integration include selected chain-control or camera metadata; links alone are never counted as integrated live feeds.
How should I compare two parts of the same Interstate?
Open the exact corridor page for each trip. Distances and driving durations are planning baselines, not live traffic estimates, and each corridor can cross different state authorities and time zones.
