As we prepare for the start of major SR 520 Montlake Project construction later this spring, our design-builder, Graham Contracting Ltd., will conduct exploratory work in the Montlake neighborhood, beginning the week of April 15.
Specifically, Graham crews will perform utility-locating and subsurface investigation. This design-discovery work will take about three weeks and will occur in the following locations:
- In the alley off East Hamlin Street, east of Montlake Boulevard East
- This is daytime work and requires a short-term closure of the alley.
- This work will not take place on Wednesdays to avoid conflict with trash and recycling collection.
- At the northeast corner of East North Street and East Montlake Place East
- This daytime work requires the closure of East North Street during work hours, for two to three days.
- Local access will be available from 24th Avenue East.
- In the Old Canal Reserve and MOHAI areas off 24th Avenue East near the SR 520 Trail
- This daytime work will require intermittent closures (5 to 10 minutes) of the SR 520 Trail.
- On SR 520 ramps and mainline
- This will require nighttime single-lane closures on the westbound off-ramp to Montlake Boulevard, the eastbound on-ramp from Montlake Boulevard, and on westbound SR 520 east of Montlake Boulevard.
This work includes pavement removal and repair as well as removing dirt with pressurized water, vacuums, and backhoes. Much of this work will occur between 7 a.m. and 7 p.m., with some work occurring at night between 7 p.m. and 7 a.m. We are applying for a temporary noise variance from the city of Seattle to conduct the nighttime work. Nearby neighbors should expect typical construction impacts, such as increased noise, vibration, dust, and truck activity. We will comply with construction best management practices as well as all city of Seattle regulations to reduce the effects of this work.
We have a number of resources to help you stay up to date about planned construction activities and find information about how to get around during construction. You can find these resources, such as our new 24-hour construction hotline (206-775-8885) and our new SR 520 Construction Corner webpages, at the bottom of this email.
We’ll provide more information about dates and times of these closures as we get closer to the work.
