Slow down and Give 'em a Brake
Drivers are advised to give themselves extra travel time and become familiar with current ramp closures and detour routes on Interstate 5 in Tacoma before heading out the door. If you're driving at night, please slow down in work zones and avoid distracted driving. Help keep our work crews safe. Slow down, pay attention, and stay calm. Work zones aren't there to personally inconvenience you. They're there to improve the roads for everyone. It's a drivers' own interest to be safe in work zones. Statewide, more than 96 percent of people injured in work zones are drivers, their passengers or passing pedestrians.
