Traffic Operations
Traffic engineers also work with the County's Road and Bridge Division in the signing and striping of all county roads, from rural gravel roads to six-lane urban arterials. Along with land development engineers, traffic engineers work with developers to ensure adequate and appropriate traffic control devices for new development. As part of the County permit processes within the Transportation Division, traffic engineers also review and approve requests for street closures within the county and perform traffic engineering studies.
