United States/Bicycle Networks
OpenStreetMap in North America (Canada, USA, Mexico) contains one international bicycle route: International Selkirk Loop (ISL) linking Idaho, Washington and British Columbia. According to Idaho Transportation Department: "The portions of the route on Idaho's state highway system are coincident with two scenic byways, the Pen d'Oreille Scenic Byway and the Panhandle Historic Rivers Passage. The latter comprises the southern leg of the International Selkirk Loop. How the route will be co-signed has not yet been determined." In late 2016 OSM entered these route data, North America's first network=icn route=bicycle. However, as this route is also shared with motor vehicles, if other (better-suited, parallel) segments specifically designated for bicycles are actual route infrastructure, please update route 6704909 with superior elements.
One quasi-national route, West New England Greenway (WNEG), is identical to USBR 7 in all three states where these two routes are coterminous; USBR 7 and WNEG are distinguished as two distinct super-relations. A potential new international route may include USBR 7, then from its northern Vermont terminus thorough Quebec, Canada on (portions of) the Champlain Bikeway to Trans Canada Trail in Iberville and on to Montréal. Then it makes sense to create a new international route relation or super-relation (network=icn). OSM awaits more discussion of which specific segments in Quebec might be included in such a potential new international bicycle route, as well as what this route might be named and how it might be signed on the ground. Champlain Bikeway crosses this international border, tagged network=rcn. Champlain Bikeway is a different route than the one described above, which includes USBR 7 south of the international border and might be a "North American Bicycle 7" route, somehow. Similar (numbered?) "international gateway" routes might emerge at or around Emerson, Manitoba, ISL/Idaho, GDMBR at Roosville, Montana/Alberta (see below) and USBRs 87, 95, 97, 10 and 8.
Adventure Cycling Association (ACA)-sponsored Great Divide Mountain Bike Route (GDMBR) touches the USA/Mexico border in New Mexico, traverses multiple states and crosses the international border at Alberta to Canada's Banff National Park. So, while it might seem correct to add network=icn or network=ncn to GDMBR, neither are correct tags, as both imply a paved route=bicycle and this route (correctly tagged route=mtb) is ~90% unpaved (again, route data are private). GDMBR displays in Lonvia's MTB renderer (z>12) as an MTB route which crosses the USA/Canada border.
A few ACA routes (private/commercial, copyrighted) in the USA (cycle_network=US:ACA) are in OSM as regional routes (network=rcn), as they both span entire states and cross state borders. These are neither international, national nor quasi-national (network=ncn: USBRs + four quasi-national routes get this tag). Most ACA routes are not in OSM, and those few which are entered may be incomplete or obsolete. If/as ACA routes are added/improved (because OSM obtains permission, something we currently do not have), some may promote to network=ncn as quasi-national or network=icn if they cross an international border. Please see Quasi-National section and USBRS Discussion page.
No bicycle routes which cross the international border between USA and Mexico are known at this time (early 2018).

The U.S. Bicycle Route System (USBRS) was formally established in 1978 as a national numbered bicycle network by the American Association of State Highway and Transportation Officials (AASHTO). In 1982, AASHTO inaugurated the first two routes into the USBRS:
- USBR 1 in North Carolina and Virginia and
- USBR 76 in Virginia.
The System languished during the 1980s and 1990s. A "National Corridor Plan" was developed during the 2000s, allowing each of the fifty states of the US to harmoniously develop USBRs using a cohesive national numbered grid of planned route corridors and a regularized numbering protocol with the following rules:
- East-West routes are even-numbered,
- North-South routes are odd-numbered,
- Spur/belt/alternate routes are preceded by a hundreds-place digit or suffixed with "A" and
- Route numbers generally increase from lower numbers in the eastern and northern USA to higher numbers in the western and southern USA.
May 2011 saw the first major expansion of the nascent System. Five new parent routes, two child routes, and one alternate route were created, along with modifications to the existing routes in Virginia and the establishment of USBR 1 in New England. Since 2012, growth has been robust. For a full history of the route by route growth of the System, please see this wiki's Discussion page's "History of the USBRS, route by route" section.
The older black and white M1-9 "numbered national bicycle route" sign shield (seen to the right and above) was MUTCD-approved from the 1970s through 2013. The newer green sign (seen to the right) is also M1-9 and will replace the black and white M1-9 in the next MUTCD edition. In the meantime states get waivers from FHWA to use the green sign. It is "interim official" and will become official on the next pass. It is AASHTO approved. The color change to green is to better differentiate it from other black and white route number signs and to align it with the color of Bike Route signs. The new sign also has the "US" imprint to show it is different from quasi-national, state and local level bike route signs (see below).
OpenStreetMap in the US contains four significant quasi-national bicycle routes, not strictly part of the USBRS:
- International Selkirk Loop (ISL, crosses into Canada, tagged cycle_network=US;CA). So, ISL is "both" international (via network=icn) and quasi-national (via US in its cycle_network=* tag). Note icn does not render in OCM.
ECG and MRT traverse several states over several thousand miles/kilometers. Hence, these two quasi-private (neither government-sanctioned nor approved by AASHTO, but public data) bicycle routes are determined to be so "national in scope" that OSM's US national cycleway network includes them as named (not numbered) routes, tagged network=ncn. While shorter than ECG and MRT, WNEG connects Canada (and Montreal via Quebec's Route Verte) to the Atlantic Ocean at ECG, so WNEG also elevates to quasi-national (it is also quasi-private, not private). Since the US has only one national numbered bicycle network (the USBRS, tagged cycle_network=US:US), quasi-national US routes should be distinguishable from these. As each quasi-national route is an independent US national-scope route, none are members of any particular national cycle network, so ECG, MRT, WNEG and the USA segments of ISL are tagged cycle_network=US. It is easy to see if a US national-scope bicycle route is national or quasi-national: national routes (USBRs) display numbered shields, quasi-national routes display acronyms.
The ncn routes (USBRs + ECG + MRT + WNEG + ISL's USA segments) traversing a single state (1A, 8, 11, 20, 21, 23, 35A, 37, 45, 45A, 50A, 70, 79, 90A, children and ISL's USA segments) are contained in single relations. The ncn routes traversing multiple states (1, 7, 10, 35, 36, 50, 76, 87, 90, 95, 97, ECG, MRT, WNEG) are contained in super-relations, each of which contains the statewide relations. Numbered network=ncn routes in the USBRS are signed with one of the two kinds of MUTCD-approved "numbered national bicycle route" signs (M1-9, seen above). Named network=ncn routes not in the USBRS (quasi-nationals ECG + MRT + WNEG + ISL's USA segments) use custom signs displaying names or acronyms of the kind seen to the right.
More historical background and information on quasi-national routes, as well as potential methods by which regional and quasi-national routes can be modified, grow and promote (possibly to USBRs) can be found in this wiki's Discussion page. Before modifying or promoting existing US regional or quasi-national bicycle routes, please read this page to better understand some of the issues involved.
State and Regional
A growing number of states (Delaware, New York, Georgia, Alabama, North Carolina, Ohio, Massachusetts, Oregon...) have their own numbered state bicycle route networks. In Ohio, some counties have begun erecting numbered state route signs. Signs may vary from the MUTCD-approved "numbered state bicycle route" sign (M1-8, seen to the right), and some local networks may use this same oval. Delaware's statewide network uses this M1-8 sign, while Maryland uses the D11-1 generic "Bike Route" sign seen below. Statewide cycleway networks use network=rcn in route relations + cycle_network=US:XY where XY is the ISO 3166-2:US code (same as postal abbreviation) for the state.
This (network=rcn) includes private (non-state/non-public, proprietary and copyrighted) named regional routes like Adventure Cycling Association's Transamerica Trail and Underground Railroad Bicycle Route: even though these are multi-state routes, each state-at-a-time segment is correctly denoted with network=rcn. Only if and when one or more state segments in a named regional route promotes, becoming a USBR ("goes first"), should a named network=ncn super-relation be created and state segments be promoted into it. In the event multiple states simultaneously receive AASHTO approval for a single-numbered USBR, create numbered network=ncn relations and include them in a new network=ncn super-relation.
Emerging in the United States are cycle_network=US:Z values for public, quasi-private and private regional cycleway network routes, where Z is a brief name or abbreviation for the name of the regional cycleway network. For example, public routes in the National Park System network (like Natchez Trace Parkway) get cycle_network=US:NPS, while (the few entered) private routes in Adventure Cycling Association's network get cycle_network=US:ACA. Use good judgement entering route data, as they may be copyrighted; only enter route data compatible with OSM's license and/or with explicit permission. Public (government-published) route data can almost always be entered into OSM, quasi-private route data can usually be entered, but private route data should not be entered (a few ACA routes have been, even though OSM may not have explicit permission). There is a tenet in OSM that "if you actually ride the route and capture those data via GPS, the resulting GPX data are yours." While this can allow otherwise-copyrighted data into OSM, be cautious entering such data: they must be "personally sourced," not copied from data which are copyrighted.
Some cities (Washington, DC; Portland, Oregon; Berkeley and San Francisco, California; Binghamton, New York; Sandpoint, Idaho) and counties (Santa Clara, California; Travis, Texas) have a local cycle network comprised of bicycle boulevards, dedicated cycleways, bike lanes and other roadways, which may or may not be designated as specific (numbered or explicitly named) routes. These signed routes use network=lcn + cycle_network=US:XY:Locality (where XY is the ISO 3166-2:US code (same as postal abbreviation) for the state and Locality is the name of the county, city or locality) in route relations if specific routes have been designated (via either the M1-8a local bike route sign oval seen here or a county/city/local government published bike route map). Otherwise, if only the D11-1 generic "Bike Route" sign seen below is posted without labeling or numbering of routes, OSM ways so signed as local bike routes should be tagged lcn=yes, either directly or as members of a network=lcn relation.
Use network=lcn in other "local" contexts such as a university (public or private) bicycle network, a localized small-to-medium-sized area with established paved bicycle routes (e.g. a private ranch), or a corporate campus such as an expansive office park (e.g. large movie studio) with its own bicycle routes. In these cases, tag each route with cycle_network=US:XY:Locality:Network_Name where XY is the ISO 3166-2:US code for the state, Locality is the name of the county and Network_Name is the name of the local cycleway network. However, be careful to avoid ambiguity with other local networks which may be named similarly; the cycle_network=* tag should assure the named network is unambiguous.
Proposed networks (at any level)
If a cycleway is part of a network with a proposed route numbering (such as proposed routes in the USBRS or the CycleNet bicycle route numbering protocol proposal in Santa Cruz, California) tag state=proposed in the route relation, which causes dashed (rather than solid) lines to render in the Cycle Map layer. Proposed routes do appear in Cycle Map layer (as dashed, not solid lines) but do not appear in Lonvia renderings.
