Backups and delays due to a couple of major bridge construction projects in Northern California could affect your Thanksgiving Holiday driving. If your holiday plans take you north of Redding or on into Oregon, be advised that you can expect moderate to major delays on Interstate 5 due to the Pit River Bridge emergency deck replacement project, 10 miles north of Redding.   The Rio Vista Bridge on Hwy 12 is also undergoing major repairs – if you’re headed through the Delta on Hwy 12 this Thanksgiving weekend, you should not be affected by closures on the Rio Vista Bridge. However, you will need to detour around the Rio Vista Bridge if you are traveling on Hwy 12 before November 21 or after November 25, Sunday through Thursday night between 9:00 pm and 5:00 am,. Caltrans asks motorists to be patient, plan extra time to reach their destinations and choose off-peak times to travel. You will want to travel with extra water and snacks. Make sure your vehicle is in good working condition and the gas tank is full. You may also want things to occupy children.
