What. A. Weekend! Sunny days, Northern Lights, Mother's Day celebrations, a POTUS visits and epic adventures made for a vibrant time. I'm assuming we're all a little sunburned, sleep deprived and worn out from all the activities. Let's start this week off right by:

  • Planning your travels with our Real-Time Travel Map
  • Avoiding drowsy or distracted driving
  • Slowing down and paying attention in our work zones
  • Hydrating with some extra coffee and water

Graffiti drone pilot program takes flight

Graffiti-battling drones. It almost sounds like something you'd see in a sci-fi movie. They could be coming soon to a bridge or overpass near you.

Protype drone sprays paint to cover graffiti.

Our Tacoma area maintenance crew is testing drone technology that can remove graffiti from hard-to-reach places. The team is learning how these drones operate, how they apply paint and if they can cover graffiti.

This could make quick work of painting over graffiti on tall retaining walls, bridges and overpasses. Learn more in our blog about the new program.

Construction, maintenance and special events

Road work ahead

We often have special events and roadwork taking place in the Northend including construction projects, maintenance and repairs. We always try to minimize any effects to travel, but sometimes it is necessary to close a lane to do the work or create a safe work zone for our crews.

While we aren't out doing a lot of roadwork this week, our crews will still be out monitoring and keeping the roads safe. If you spot them, slow down and give them space to work! A huge thanks to our crews for all of their hard work through the holidays.
