Seattle-area Microsoft employees who are showing up in the office three days a week are also showing up on roadways and impacting commuters’ speeds, according to new data from traffic analysis company Inrix.
Inrix measured travel speeds on eastbound and westbound SR 520 and southbound and northbound I-405 during the weeks of Feb. 23 and March 2. Many of Microsoft’s more than 50,000 employees in the region rely on the roadways and bridges connecting Seattle and the Eastside to the company’s headquarters campus in Redmond, Wash.
The data shows speeds on 520 dropped across all days during the first week, with speeds on Tuesday, Wednesday, and Thursday showing the slowest travel speeds over just over 30 mph.
Morning commute speeds between Tukwila and Bellevue fell as much as 35% and as much as 25% between Lynnwood and Bellevue. The evening commute saw speeds drops as much as 27% between Bellevue and Tukwila on Friday while speeds fell 21% northbound between Bellevue and Lynnwood, Inrix reported.
Microsoft isn’t dictating from above which three days people will need to be in the office. Specifics are left to individual teams and managers. Some groups may require more than three days, and certain customer-facing roles like field sales and consultants are exempt.
The region’s roadways could get some relief when Sound Transit’s Crosslake Connection opens March 28, finally linking Seattle and the Eastside by light rail across Lake Washington — connecting downtown Seattle to downtown Bellevue and the Redmond Technology station at Microsoft headquarters.
