I-90 - North Fork Issaquah Creek - Fish Passage - Photos

WSDOT will replace the two round culverts with a large box culvert in summer 2017.
North Fork Issaquah Creek currently passes through two round culverts under the Interstate 90 Front Street on- and off-ramps in Issaquah.

The two culverts that channel North Fork Issaquah Creek under I-90 on- and off-ramps are a barrier to fish.
The current set of culverts that channel North Fork Issaquah Creek under Interstate 90 on- and off-ramps is a barrier to fish. Flows are often too fast or too shallow for fish to swim through.
