About the Traffic and Road Maintenance Section

The Traffic and Road Maintenance Section of the King County Road Services Division is responsible for over 1,500 miles of paved roadway and 180 bridges in unincorporated areas of King County. It is our mission to enhance and maintain the roadways in an efficient and environmentally responsible manner.  As part of this effort, we strive to be a leader and environmental steward, through the development and implementation of the Regional Roads Maintenance Endangered Species Act (ESA) Program Guidelines. These guidelines ensure that sound environmental practices are used when performing work in the road right-of-way.

We also provide miscellaneous road-related services to contract cities and other government agencies.  In an effort to provide for safe road travel, all roads in unincorporated King County receive 24-hour emergency response assistance, as do roads in selected cities under contract with King County.

This would include purchasing sand and sandbags in advance of flood season. For more information on the King County Flood Warning system, preparing for flooding, important phone numbers and links to sign up for emergency notification, and obtaining sand and sand bags, see the flooding services and information maintained by the Water and Land Resources Division or call the Flood Warning Center at 206-296-4535 or 800-768-7932.

Call-Before-You-Dig is part of a national program that seeks to avoid the results of accidentally hitting utility pipes during excavation. These accidents are always costly and can result in serious injuries or death. It doesn't make any difference whether you are a contractor or an individual, call before you dig. It doesn't cost you anything to have someone come out an mark your lines, but it will cost you if you don't have the lines marked and you damage one. If you hire a contractor for work which involves digging, be sure that the contractor has called the Utilities Locate Center.

As part of the program, licensed technicians perform controlled herbicide spraying along some road shoulders starting in the spring and going through the summer. The spraying is performed to help reduce safety hazards for pedestrians, motorists and bicyclists. The spraying also controls noxious weeds that are toxic to some animals and pose environmental risks to native vegetation. Learn more.
