SR 520 Eastside Project June 2011 Closure
Dirt and rock from a 30-foot-deep trench on SR 520 is piled during the full weekend closure of the highway.
From June 17-20, 2011, crews closed SR 520 for construction on the east side of Lake Washington. The centerpieces of the work included the demolition of a pedestrian bridge near Medina and the installation of a massive prebuilt concrete fish-passable culvert in Bellevue.
The trench crosses all lanes of SR 520 west of Bellevue Way Northeast and will contain a new, larger culvert that will improve fish migration. This is the first of eight culverts crossing SR 520 that will be installed between Medina and Bellevue during the next three years.
