In addition to the roads, there are 209 bridge and culvert structures currently maintained by the region.

Traffic Enforcement unit handles enforcement of traffic laws, except on the King's Highways, which are patrolled by the Ontario Provincial Police. Speed limits on regional roads vary between 50 and 80 kilometres per hour. Police in Durham will generally not set speed traps, as the region encourages the safe flow of traffic, and punishes unsafe driving rather than speed limits. Maintenance and snow clearing is performed by the Durham Works Department. Five depots operate throughout the region in addition to the traffic operations centre in Whitby.
