Northgate Pedestrian Bridge Update – April 2020


Northgate Ped/Bike Bridge construction update

Work is continuing during the current coronavirus restrictions. Here is a statement from SDOT:

At the City of Seattle, we are continuing to follow guidance from federal, state, and local leaders and our public health partners regarding COVID-19.  State officials have determined that work on public works projects can continue during the Governor’s stay-at-home order provided that appropriate safety measures are in place. 

The Seattle Department of Transportation is continuing with essential transportation (public works) projects to the greatest extent practicable during these times. The health and safety of our workers and the public is our first priority. Our contractors have updated their Health and Safety Plans to incorporate best management practices with respect to COVID-19 throughout our construction work sites. If a situation arises where a contractor is unable to maintain these practices on a work site, or the Governor orders that work on public works projects must stop, the contractor shall temporarily suspend work until the work can be performed safely and legally. 

We will notify you if there are any changes to the project schedule or planned work.
