UPDATE: Due to inclement weather in the forecast, we have moved the start of the 5th Avenue partial closure to Sunday, Feb. 15 at 9:00 p.m. All other closure dates remain the same. 

Several weeks of major closures are coming to NE 145th Street/State Route 523 and 5th Avenue NE for construction on the 145th Street Corridor and I-5 Interchange projects. Starting Sunday, Feb. 15, 5th Avenue NE will close just north of the 145th Street intersection. The entire NE 145th Street and 5th Avenue NE intersection will then close beginning Thursday, March 19. All closures will reopen on March 31. The Shoreline South/148th Station and the on-ramp to northbound I-5 will be accessible from NE 155th Street during all closures. The closures will allow crews working for the City of Shoreline to build the roundabout east of I-5 and complete sidewalk improvements around the intersection.

The closures will include the following impacts:

• Starting Sunday, Feb. 15 at 9 p.m.
  • 5th Avenue NE between NE 145th Street and the northbound I-5 on-ramp will be closed. 
  • 6th and 8th Avenues NE will remain closed to traffic from NE 145th Street.
  • A signed pedestrian path will be available on the west side of 5th Avenue NE. 

• Starting Thursday, March 19 at 9 p.m.   
  • The NE 145th Street overpass will be closed.  
  • The northbound I-5 off-ramp to NE 145th Street will be closed. 
  • 5th Avenue NE between NE 145th Street and the northbound I-5 on-ramp will be closed.  
  • 6th and 8th Avenues NE at NE 145th Street will be closed. 
  • A signed pedestrian path will be available on the north side of the NE 145th Street overpass and west side of 5th Avenue NE.

The City of Shoreline is working in partnership with the Washington State Department of Transportation and Seattle Department of Transportation to close these areas while maintaining a safe flow of traffic. Throughout the closure, signed detours will be in place. People are encouraged to allow extra travel time, avoid the area if possible, and use alternate routes.

NE 145th Street is still an active work zone. For everyone’s safety, drivers should reduce speed in the area and pay attention to construction signs and barrels.

“Constructing the roundabout east of I-5 marks a major step forward for our city’s transportation system,” said Tricia Juhnke, City of Shoreline Public Works Director. “We know these closures are disruptive and we appreciate everyone’s continued patience.”

Once NE 145th Street reopens on March 31, the new roundabout east of the I-5 overpass will be open in a temporary single lane configuration. The roundabout will look like the roundabout constructed on the west side of I-5 last year.

Later this spring, crews will install signage, landscaping, and do the final asphalt paving on both 145th Street roundabouts. They will then be restriped to be two-lane roundabouts.
