520 Ramp Removal For Next Few Months

WSDOT sent this information about ramp removal work starting today:

Heads up: Ramp removal work near Lake Washington Boulevard

The only sections remaining of the old westbound SR 520 off-ramp to Lake Washington Boulevard and the R.H. Thomson “Ramps to Nowhere” are those that stand over water. In the next two weeks, crews will prepare the work site so that active removal work of these spans begins today.  
Hoe Ram and Muncher
What to expect:
  • Construction hours: Ramp-removal crews plan to work 10-hour days, seven days a week. All impact activity, such as jackhammering or hoe ramming, will be completed between 7 a.m. and 10 p.m. during the weekdays and 9 a.m. and 10 p.m. on the weekends. All nonimpact construction activities, such as processing ramp rubble, munching concrete or moving equipment around the site, may take place before 7 a.m. and after 10 p.m. Inspectors on site will ensure that nighttime crews stay under the decibel levels permitted by the city of Seattle noise ordinance. 
  • Noise: As crews complete this removal activity, nearby neighbors may hear hoe rams or munchers (both pictured to the right). 
  • Vibrations: Neighbors may feel vibrations from the ramp-removal work.
  • Lights: Neighbors may see lights used during nighttime work to keep the site illuminated and safe for crewmembers. Crews will make every effort to keep lights pointed away from homes, where feasible.
The removal work is expected to continue for the next three to four months. We will keep you updated through these emails as the work progresses. If you have any questions or concerns regarding the ramp-removal work, please feel free to call the SR 520 24-hour hotline at 206-708-4657 or email us at
