Three-minute indoor walk from Evans Terminal check-in
Big Blue Deck is the attached long-term garage for the Evans Terminal at DTW, with a signed walking route that takes about 3 minutes from your car to the AA and United check-in counters. It sits directly across from the terminal and connects via enclosed bridges, so you stay covered from the moment you park through security.
Rates run higher than the Green Lots and off-airport options, so most flyers treat Big Blue as the pay-up choice for trips under 4–5 days rather than week-long travel. One FlyerTalk regular specifically says they use Big Blue for weekend Evans departures, then switch to off-airport once a trip stretches past that 4–5 day mark because daily costs add up fast.
The deck connects straight into the Evans Terminal via multiple enclosed pedestrian bridges, with color-coded signage on each level to mark which bridge you’re near. VisitDetroit notes that this enclosed connection gives covered access year-round, which matters in January when Detroit wind and snow make an outdoor shuttle wait feel a lot longer than 10 minutes.
Complaints in r/Detroit focus on wayfinding inside Big Blue, especially figuring out which elevator bank hits which pedestrian bridge. First-timers sometimes ride up, follow signs, then realize they picked the wrong side and have to backtrack across a level or down a floor, which can burn 5–10 minutes if you’re cutting it close.
Regulars snap a quick photo of the nearest color-coded sign or level marker when they park, then match it on return so they don’t walk out the wrong bridge. One simple tip: note your level and row, plus “Evans bridge” in your phone’s notes, so after a late-night arrival you can head to the right elevator without laps around the garage.
