Construction crews took advantage of the annual maintenance closure of the SR 520 bridge last weekend, installing a massive fish-friendly culvert underneath all lanes of SR 520.

WSDOT released time lapse view of the July 12-15 weekend project.

In addition to the project to improve fish habitat, other SR 520 projects this year include reducing noise, installing stormwater treatment and detention facilities and constructing new lids along Evergreen Point Road.
