A frontage road (also access road, service road, parallel road, etc.) is a minor road running parallel to a higher-speed more major road, often in an urban setting. The frontage road is connected at some points with the major road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. Functionally they usually behave as collector roads for local traffic along the sides of the highway. A frontage road if often, but not always a one-way road.

How to tag?

Do not use the highway=*_link tag for the frontage road. Use one of the normal highway=* tags. As the frontage road is minor then the major road, it must also have a minor highway=* tag than the major road – often highway=residential.

Example: If the major road is “tertiary”, then the frontage road is neither “tertiary” nor “tertiary_link”. It has a minor type: can be “unclassified”, “residential”…
