Field work starting along the SR 522/NE 145th BRT corridor

Publish Date

To continue advancing the design of the SR 522/NE 145th Bus Rapid Transit project, Sound Transit will need to conduct some field work along the corridor. Sound Transit will contact property owners to request access to private property and to conduct field work. After receiving approval from property owners in the form of Right of Entry (ROE) authorizations, field crews will begin performing survey work, geotechnical drilling, noise and/or vibration monitoring, and other activities essential for advancing the project's design.  

What are Right of Entry (ROE) Authorizations?

  • ROE authorizations are voluntary agreements signed by both ST and property owners
  • ROE authorizations allows Sound Transit representatives access to property for specific and agreed upon purposes
  • Sound Transit will give property owners advance notice of any field work to minimize disruptions to occupants and tenants
  • Most activities take between 1-3 days to complete

Additional fieldwork

Those who live and/or travel the project corridor will also notice crews preforming field work in the public right of way. If this work presents any impacts to traffic, we will provide advanced notification so you know what to expect. 

What's next?

Sound Transit representatives will begin contacting select property owners in the next few weeks to seek authorization and answer questions about the ROE process. Once Sound Transit has collected authorizations from property owners, field work will take place over the next 24 months. 

Your cooperation and assistance are highly valued as we complete our field work during this phase of the project. As always if you have any questions please reach out to us at
