Interstate Highway relations

Part of United States mapping project.

Tag	Comment
type=route	Required.
network=US:I, US:I:BUSINESS, US:I:DOWNTOWN, US:I:FUTURE	Required. Business, downtown and future routes have their own signage
ref=*	Required. ex. 90
route=road	Required.
modifier=*	Required for truck, HOV and express routes. ex. "TRUCK"
addr:state=xx	Optional. xx = State Postal Code e.g. OH;KY;IN for I-275 in Ohio/Kentucky/Indiana. FL for I-275 in Florida.
symbol=*	Optional. URL to an SVG image of the route shield. You can find these in Wikimedia commons (see the Wikipedia page for each route).
url=*	Optional. URL to a page where more can be learned about this route.

Name Tag should not be marked on same relation unless the entire system has the same name. One relation can cover both directions.

Avoid relation proliferation, if possible. If a relation already exists for the route you are tagging, you can reuse the existing relation in your area. In Potlatch, do a relation search on the existing relation's number.
