Heavy work last weekend to remove old Montlake Boulevard overpass

Montlake Project crews completed a major milestone last weekend by demolishing the Montlake Boulevard overpass across SR 520. The entire bridge structure had to be brought down and trucked away in just a little over two days so that SR 520 could be reopened for the Monday morning commute. To accomplish this, the contractor brought to bear its entire arsenal of demolition machinery, including four giant excavators with hydraulic jackhammers. These machines worked around the clock from Friday night into the early morning hours of Sunday. The remainder of the weekend was devoted to loading and hauling away all the concrete debris. We’re grateful for the patience and understanding of nearby residents.  

Three demolition excavators tear down part of the old Montlake Boulevard overpass.
