WSDOT: 116 summer construction projects scheduled, plan ahead for weekend closures

The busy summer construction season is in full swing, and the Washington State Department of Transportation (WSDOT) is warning drivers to be aware, plan ahead, and pay attention to slew of projects happening in the Seattle area this weekend.

According to WSDOT, there are 116 construction projects scheduled this summer on state highways – and this is not counting basic maintenance and local projects. WSDOT also released a blog post explaining that just about every major event happening this summer, like sporting events, concerts and festivals, will likely be interrupted by construction. According to their event calendar, there are only 23 days this entire summer with no major events happening, and only one weekend with nothing going on.
