In order create a county in which those who reside and invest here can prosper and achieve well-being, Public Works strives to provide a County roadway system that supports the safe, efficient, and convenient movement of people and goods. Public Works accomplishes this through a variety of functions that are performed within the Traffic Division:
Maintain Records of County Roads and Related Assets
The County of San Bernardino maintains over 2,500 miles of roads in the unincorporated areas which is known as the County Maintained Road System (CMRS). The Traffic Division is responsible for documenting additions and deletions, as approved by the Board of Supervisors, to the CMRS.
In addition, the County has over 100,000 traffic control devices such as signs, pavement markings and guard rails installed on the CMRS. The Traffic Division is responsible for keeping records on the location and condition of these devices.
The County also has over 300 bridges that are located on the CMRS. Some of these bridges have weight limits. The Traffic Division maintains a listing of these bridge locations and any weight limits approved by the Board of Supervisors.
Lastly, there are over 80 railroad-highway grade crossings involving the CMRS. The Traffic Division maintains a listing of these crossings.
When a new development is proposed within the unincorporated areas of the County, the Traffic Division provides a review of the traffic related portions in cooperation with the Department of Land Use Services. For projects which generate a sufficient amount of traffic, more than 100 trips during the peak hour, or are in areas where congestion exists, a traffic study may be required as part of the project’s approval process. The Traffic Division is responsible for reviewing and approving these traffic studies.
Once a project has been approved by the Board of Supervisors, developers will submit street improvement plans for review and approval. The Traffic Division reviews these plans with respect to the installation of new or the modification of existing signs, roadway striping and pavement markings. If the project involves traffic signals, the Traffic Division will also review the associated signal plans.
Once the street improvement plans have been approved and as part of the permit process through Public Works, the Traffic Division will review plans for controlling traffic during the construction.
Development Related Fees
Public Works collects the following fees for our Development Review activities:
- Traffic Study Review Fee: Developers are charged actual cost for the time required to review studies. When a study is submitted the Developer will include a deposit, to the Department of Public Works, of either $400 or $3,400 depending on the complexity of the review.
- Fair Share Contributions, also known as Ad Hoc fees: When a traffic study finds that a development has shared impacts at intersections, fair share contributions will be conditioned upon the development and collected by the Department of Public Works at the time of application for a building permit.
- Regional Transportation Mitigation Fee: View the plan areas and fee schedule.
Design of Traffic Plans
For capital improvement projects designed by Public Works, the Traffic Division is responsible for preparing plans, specifications and cost estimates for signing and striping and traffic signals. During the construction of these projects, the Traffic Division may prepare or provide review of traffic control plans to handle traffic during construction. The Traffic Division will also provide final inspection services for signing, striping and traffic signals.
The County has over 80 traffic signals and 30 flashing beacons located on the CMRS. The Traffic Division is responsible for the operation and maintenance of these locations. The Traffic Division also conducts analyses of traffic signal warrants and maintains a list of intersections where traffic signals may be needed. The Traffic Division oversees the maintenance of signals and flashing beacons through a contract awarded to a private contractor specializing in such maintenance. The current contract expires on June 30, 2015 and was awarded to Siemens Industry, Inc.
To check if the signal you are interested in is County maintained, view the maintained signal list.

Outside of business hours, on weekends, and holidays, please contact County Communications at (909) 356-3805 or Siemens Industry, Inc. at (800) LIGHTS-ON or (800) 544-8766.

- Street Name Signs
