Tagging suggestions for Ohio

Most of these examples are taken from the Cincinnati area, but feel free to add your own from elsewhere in the state:

Key	Value	Description	Examples
highway	motorway	Interstate highways, including loops and spurs; significant portions of US and state routes built to Interstate standards (high-speed, fully access-controlled).	I-71 I-75 I-275 Ohio Turnpike (I-76/80/90) Ronald Reagan Cross County Highway (SR 126)
	trunk	Selected U.S. and state routes not built to Interstate standards. High-speed, limited-access, divided highways with at least two lanes in each direction. May have occasional traffic lights and unlit street-level crossings, but mostly controlled-access with on- and off-ramps. Two-lane undivided (but still limited-access) sections of Trunk might make sense if they are extensions of divided Trunk highway or Motorway.	Appalachian Highway (SR 32) Columbia Parkway (US 50) Various Cincinnati viaducts
	primary	Other U.S. routes; major state routes, such as those that connect larger county seats not directly connected by US routes, or are important connectors between primary or higher roads. Sections of primary roads should not "dead-end" at lower-class roads.	Montgomery Road (US 22 / SR 3) US 42 SR 4 from Springfield to Sandusky
	secondary	Other state routes; good connecting roads, such as those that connect cities not directly connected by state routes, or are important connectors between secondary or higher roads. Sections of secondary roads should not "dead-end" at lower-class roads.	SR 48
	tertiary	County routes (signed or unsigned) and other major local roads, typically along section lines or connecting towns.	Loveland–Miamiville Road (CR 75)
	unclassified	Rural roads, serving mostly farmland or forest properties, of little to no value as through routes.
	residential	City/neighborhood streets not qualifying as tertiary or higher, or rural roads which have become lined with houses.
ref	I-##	Interstate highways.	I-71 I-670
	US ##	US highways.	US 40
	SR ## OH ## US:OH ##	State routes. The shorter forms are more likely to be rendered in Mapnik. While the US:OH form is specific, it doesn't look great on maps or in directions, and that specificity can also be accomplished using route relations.	SR 13
	CR ##	County routes. This probably should only be used for roads where the county route number is signed as clearly as on a state route.	CR 33A
	TR ##	Township routes. This probably should only be used for roads where the township route number is signed as clearly as on a state route.

See United States roads tagging for more information.

Relations

Route relations

Some highways are moving from the old way-based tagging scheme to the new route relations. Each relation should have network and ref keys, as well as a symbol key with the URL to the SVG image found on the highway's Wikipedia article. If the entire route has the same name, the name key may also be specified on the relation.

For divided highways in Ohio, roles are entered when adding relations to the constituent ways. (Potlatch provides a small textbox on the relation line for entering roles.) The de facto standard in Ohio is to add roles corresponding to the signposted direction of each carriageway (i.e., north).

Interstate highways

Mark all member relations as network=US:I. Please keep this list synchronized with Interstate Highways Relations.

Boundary relations

Counties

County borders were originally supplied by the USGS. The following counties' borders are being assigned to relations, merged with adjacent county borders (rather than overlapping them), and attached to TIGER ways and river center-lines (where appropriate) for improved accuracy.

When "TIGERifying" county borders, please ensure that any road crossing a county line is joined up properly. The roads seem to have been imported county-by-county, causing the roads to be disconnected.

Code	Name	Relation	Way merging	TIGERification
BRO	Brown	163283 163283	With Clermont	West
BUT	Butler	104783 104783	With Warren	South and east

To do

• The map is still missing most of Ohio's major bicycle routes, such as the Ohio-to-Erie Trail, of which only the Little Miami Scenic Trail has been mapped. Some counties have begun numbering these routes, so inclusion in OpenStreetMap could be very helpful.
• Some counties in Southwestern Ohio are now using Relation:boundary along shared ways for their borders.
