What’s Happening Now

Over the next several months, work crews will be in the project area to perform investigative activities. Activities include site visits and evaluation, survey, utility locates, and pipe cleaning and inspection.

Some investigative activities will require restricting parking and temporarily closing travel lanes. The traveling public should expect minor traffic delays.

Information gathered will help determine the repair locations, construction methods, and how to minimize construction impacts on residents and businesses. Learn more about these pre-construction activities.
