November 26–December 3, 2025

In addition to the projects listed below that may impact your commute, you can find information on work being done to enhance our City on the Capital Improvement Projects Map and the Road Construction Map.

Happy Thanksgiving!

Whether you’re gathering close to home or traveling, we hope you have a wonderful Thanksgiving with friends and loved ones. As you enjoy the long weekend, please keep these simple holiday safety tips in mind:

• Keep an emergency kit in your vehicle. Flashlights, water, and basic tools can go a long way during holiday travel.

• Expect crowded shopping centers and busy parking lots. Stay alert for pedestrians carrying bags, carts, and little ones.

• Celebrate responsibly. Never drive under the influence of alcohol, drugs, or any medication that impairs your ability to drive. Use a sober driver or a ride service.

• Report unsafe driving. If you see a suspected drunk driver, dial 911.

Have a safe and happy Thanksgiving!
