Overview
The Salmon Creek Interchange Project reduced traffic congestion and improved safety in the fast-growing Salmon Creek area by constructing a new I-5 interchange at NE 139th Street, improving the I-205 northbound off-ramp to NE 134th Street, and constructing other local road improvements.

The project relocated the northbound I-5 on-ramp entrance from 134th St. to 139th St.
It added new lanes on both directions of I-5 between NE 139th Street and NE 179th Street, and relocates the C-TRAN Park & Ride lot from NE 134th Street to a new location near the corner of NE 139th Street and NE 10th Avenue.

Additionally, it added an exit-only lane to NE 134th Street from I-205 NB resulting in a two-lane off-ramp. It also realigned northbound I-205 to the east at NE 139th Street to accommodate vertical clearance requirements with NE 139th Street. It widened the intersection of NE 20th Ave and NE 139th St.
Widens NE 10th Avenue from NE 134th Street to NE 141st Street and constructed a round-a-bout at intersection of NE 10th Ave. and NE 136th St.

How You Benefit
Cross GlyphImproves Safety
The project provides safety benefits to motorists and pedestrians. Without the project, it was anticipated that the traffic back up on the northbound off-ramps to NE 134th Street from both I-5 and I-205 would extend to approximately 1,000 feet. This prevented traffic from clearing the I-5 and I-205 off ramps. With this project complete, these back-ups are reduced to about 300 feet. In turn, this will reduce the collision rates on the northbound off-ramp from I-5 by keeping stopped vehicles from backing up onto the freeway at the exit areas.
Car GlyphRelieves Congestion
This project reduces congestion and travel time at this interchange by preventing vehicles on the I-5 and I-205 off ramps at NE 134th Street from backing up on to the interstates.
