Recent data from traffic analysis firm Inrix indicates that the morning commute in the Seattle area has been significantly impacted by Microsoft employees returning to the office three days a week. Travel speeds on key roadways, including SR 520 and I-405, dropped as much as 35% during peak hours, with average speeds hovering just above 30 mph.
During the weeks of February 23 and March 2, Inrix observed that commutes between Tukwila and Bellevue experienced the most severe delays. The evening rush also showed declines, with speeds falling up to 27% on Fridays. Microsoft’s return-to-office policy does not mandate which specific days employees must attend, allowing flexibility for teams and managers.
A potential easing of congestion is anticipated with the opening of Sound Transit’s Crosslake Connection on March 28, which will provide a light rail link between Seattle and the Eastside, including direct access to Microsoft’s Redmond headquarters.
