Washington State is home to forests, mountains, rivers, lakes, volcanoes, beaches and bays. So, it's not surprising that a state with such natural beauty works hard to find a balance between safeguarding the environment, protecting consumers and maintaining a thriving business community. Like most western states, Washington has a fair amount of state and city level licenses. However, it maintains fewer than neighboring Oregon or giant California below that.
In Washington, a construction zone traffic control contractor prepares or removes lane closures, flagging, or traffic diversions, utilizing portable devices, such as cones, delineators, barricades, sign stands, flashing beacons, flashing arrow trailers, and changeable message signs, on roadways, including, but not limited to, public streets, highways, or any public conveyance.
