Advance notice of any service disruption or construction impacts will be provided to residents in-person, through letter, email and website updates.

Below are some impacts you may experience:

  • Traffic delays: The project may cause traffic delays, lane shifts or lane restrictions. We will make every effort to minimize any potential inconvenience and provide you with advance notice when disruptions must occur.
