As our island welcomes the world, let’s show our community pride:

• Ride and drive with aloha – slow down, be patient, and respect road officials and volunteers.
• Share the road – expect more cyclists and pedestrians than usual.
• Cheer with aloha – encourage athletes and support neighbors impacted by traffic changes.
