Tagging relations

Use the following tags when creating or editing an Interstate relation:

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 instead of I-90, 35W instead of I-35W
route=road Required.
modifier=* Required for truck, HOV and express routes. ex. "TRUCK"
addr:state=xx Required. xx = State Postal Code e.g. FL for I-275 in Florida. Either 1 or 2 relationships per state (see below).
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).
wikipedia=* Optional. Title of the Wikipedia page about the route.
name=* Deprecated. The name=* tag should not be marked on same relation unless the entire system has the same name.

Directionality

Most, but not all of these highways should be divided into separate ways (dual carriageways) for each direction by now. At the moment, there are two different approaches for indicating which direction a particular way goes. Although it may look hard, it is actually relatively simple to convert from one to the other using JOSM and the relation analyzer. Right now, there is no consensus on which method is better, and mappers should not change the approach used for a completed relation.

  • One relation for each direction of the highway.
    • Simplifies relation analysis and speeds up editing and browsing.
    • For example, one direction would contain only northbound ways, while the other would contain only southbound ways. Mappers generally add the direction to the name of the relation (but this contradicts the above guidance on using the name tag). Example: way I 5 north.
  • One relation for both directions of the highway.
    • Simplifies creation and verification of relations.
    • Relation analyzer supports this now, but slightly more processor-intensive on the analysis server.
    • Enter a "role" for each constituent way. Potlatch provides a small textbox on the same row as the relation for entering roles.
    • The role should correspond to the carriageway's signposted direction (i.e., north for a northbound set of lanes). Nothing else should be used for the role (unless there are multiple roadways, such as express and local, or upper and lower). Do not tag ways themselves with a "role" tag! Example: way I 71 north; US 52 east.

State Lines / Administrative Boundaries

Interstate Highway relations should be on a state-by-state basis, e.g. I-90 in MA, I-90 in NY, I-90 in PA, and so forth. A rule of thumb would be if the milestone number resets, start a new relation. Tie all state relations together with a SuperRelation for the interstate.

Avoid relation proliferation, if possible; if a suitable relation already exists for your state on 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.

Additional Tags

Interstate relation tags refer to the entire stretch of interstate they cover. See Interstate Highways for advice on tagging physical details (speed limit, etc...) of the ways themselves.
