The '''United States Bicycle Route System''' (abbreviated '''USBRS''') is the [[national cycling route network]] of the [[United States]]. It consists of interstate [[long-distance cycling route]]s that use multiple types of bicycling infrastructure, including off-road paths, bicycle lanes, and low-traffic roads. As with the complementary [[United States Numbered Highways]] system for motorists, each '''U.S. Bicycle Route''' is maintained by [[State governments of the United States|state]] and [[Local government in the United States|local government]]s. The USBRS is intended to eventually traverse the entire country, like the [[Dutch National Cycle Routes]] and the [[United Kingdom]]'s [[National Cycle Network]], yet at a scale similar to the [[EuroVelo]] network that spans Europe.

The USBRS was established in 1978 by the [[American Association of State Highway and Transportation Officials]] (AASHTO), the same body that coordinates the numbering of [[Interstate Highway System|Interstate highways]] and U.S. Routes. The first two U.S. Bicycle Routes were established in 1982 and remained the only two until 2011. Steady growth and interest in the system has followed since.<ref name="lahood-fastlane">{{cite web |url = http://fastlane.dot.gov/2010/07/us-bicycle-route-system-begins-connecting-america.html |title = US Bicycle Route System begins connecting America |first = Ray |last = Lahood |publisher = [[United States Department of Transportation]] |date = July 2, 2010 |access-date = July 7, 2010 |archive-date = July 5, 2010 |archive-url = https://web.archive.org/web/20100705234950/http://fastlane.dot.gov/2010/07/us-bicycle-route-system-begins-connecting-america.html |url-status = dead }}</ref><ref name=ACA-release-May2011/><ref name=ACA-blog-May2011/> {{As of|2022|11}}, 29 parent routes and 24 [[special route|child routes]] extend {{convert|18953|mi}} across 34 [[U.S. state|state]]s and the [[Washington, D.C.|District of Columbia]].<ref name="ACA November 2022" /> The system, once fully connected, is projected to encompass over {{convert|50000|mi}} of bike routes.<ref name="USBR50MD-23TN"/>

==Layout==
Like United States Numbered Highways and many national routing systems, the U.S. Bicycle Route system is designed to roughly follow a grid. Mainline routes are the major cross-country routes and are represented with one- or two-digit numbers. Even-numbered routes are planned to primarily run east–west, with low-numbered routes in the north and high-numbered routes in the south. Odd-numbered routes will primarily run north–south, with low-numbered routes starting in the east and ascending in number toward the west. Three-digit numbers are assigned to auxiliary routes, with the last two digits denoting the parent that the auxiliary connects to. Much like other routing systems, the grid is sometimes violated; for example, [[U.S. Bicycle Route 76]] (USBR 76) is projected to turn to the north in Colorado and end in Oregon as opposed to California, south of (and temporarily concurrent with) [[U.S. Bicycle Route 20|USBR 20]] but far north of [[U.S. Bicycle Route 50|USBR 50]]. As with [[List of auxiliary Interstate Highways|auxiliary Interstate Highways]], two distinct U.S. Bicycle Routes in two different states along the same mainline route may share the same three-digit number without any plan to connect the routes. The first example of this repetition occurred in 2021 with the approval of [[U.S. Bicycle Route 230 (Ohio)|USBR&nbsp;230 in Ohio]], which is not intended to connect to an existing [[U.S. Bicycle Route 230 (Wisconsin)|USBR&nbsp;230 in Wisconsin]].<ref name="ACA August 2021">{{cite press release |title = U.S. Bicycle Route System Adds 2,903 Miles of New Routes in 5 States |publisher = [[Adventure Cycling Association]] |location = Missoula, Montana |date = August 9, 2021 |accessdate = August 10, 2021 |url = https://www.adventurecycling.org/about-us/media/press-releases/u-s-bicycle-route-system-adds-2-903-miles-of-new-routes-in-5-states/ |archive-date = October 20, 2021 |archive-url = https://web.archive.org/web/20211020010539/https://www.adventurecycling.org/about-us/media/press-releases/u-s-bicycle-route-system-adds-2-903-miles-of-new-routes-in-5-states/ |url-status = live }}</ref>

The existing [[U.S. Bicycle Route 1|USBR 1]] will be the easternmost route, though [[U.S. Bicycle Route 5|USBR 5]] will run farther east of it in Virginia and [[the Carolinas]]. The westernmost and northernmost routes are [[U.S. Bicycle Route 97|USBR 97]] and [[U.S. Bicycle Route 8|USBR 8]], respectively, both of which are in the state of Alaska, but USBR 97 also enters Washington. [[Contiguous United States|Outside of Alaska]], the westernmost route is expected to be [[U.S. Bicycle Route 95|USBR 95]] and the northernmost [[U.S. Bicycle Route 8|USBR 8]]. [[U.S. Bicycle Route 90|USBR 90]] is expected to be the southernmost route.<ref name="corridor-plan"/> Despite the analogy the system has to the U.S. Highway system, the USBRS's route numbers do not necessarily trace the same route as the corresponding U.S. Highway number; for example, while USBR 1 will run close to the East Coast and thus parallel [[U.S. Route 1]] (US 1), the projected route of USBR 10 generally follows [[U.S. Route 2|US 2]].

In order for a route to qualify as a U.S. Bike Route, it needs to connect two or more states, connect multiple U.S. Bike Routes, or connect a U.S. Bike Route with a national border.

==History==
The USBRS was established in 1978 by [[American Association of State Highway and Transportation Officials|AASHTO]] for the purpose of "facilitat[ing] travel between the states over routes which have been identified as being more suitable than others for cycling."<ref>{{cite web |author = American Association of State Highway and Transportation Officials |url = http://www.maine.gov/mdot/maines-transportation-systems/route-number-designations.php |title = Route Number Designations |via = Maine Department of Transportation |date = June 30, 1982 |access-date = May 12, 2006 |archive-date = May 15, 2006 |archive-url = https://web.archive.org/web/20060515221947/http://www.maine.gov/mdot/maines-transportation-systems/route-number-designations.php |url-status = live }}</ref>

The first routes were defined in 1982: [[U.S. Bicycle Route 1]] (USBR 1) from [[North Carolina]] to Virginia, and the stretch of [[U.S. Bicycle Route 76|USBR 76]] from [[Illinois]] through [[Kentucky]] to Virginia. These two routes remained the only routes in the system until 2011. In the interim, only minor routing changes had been made in [[Virginia]].

AASHTO established a new task force in 2003 to study expansion of the system.<ref name="lahood-fastlane"/><ref name="AASHTO Moeur">{{cite web |first = Richard C. |last = Moeur |url = http://www.transportation.org/sites/scote/docs/2004meeting/presentations/Moeur.pdf |title = AASHTO Ad Hoc Task Force on U.S. Bicycle Routes |publisher = American Association of State Highway and Transportation Officials |access-date = May 12, 2006 |archive-url = https://web.archive.org/web/20060525150626/http://www.transportation.org/sites/scote/docs/2004meeting/presentations/Moeur.pdf |archive-date = May 25, 2006 }}</ref><ref>{{cite web |url = http://www.transportation.org/sites/scote/docs/Moeur-US%20Bike%20Routes.pdf |title = AASHTO Task Force on Numbered Bicycle Routes |publisher = American Association of State Highway and Transportation Official |access-date = January 27, 2007 }}</ref> The task force included state and federal highway officials and representatives from bicycling organizations. In October 2008, AASHTO approved a national-level corridor and route designation plan.<ref>{{cite web |author = Adventure Cycling Association |url = http://www.adventurecycling.org/routes/nbrn/thedream.cfm |publisher = Adventure Cycling Association |title = Background on Current USBRS Effort |access-date = June 28, 2009 |archive-date = February 9, 2009 |archive-url = https://web.archive.org/web/20090209010259/http://adventurecycling.org/routes/nbrn/thedream.cfm |url-status = live }}</ref> Other organizations involved in the effort include state departments of transportation, the [[Federal Highway Administration]] (FHWA), and the [[Adventure Cycling Association]].

In 2009, the [[U.S. House of Representatives]] proposed moving the U.S. Bicycle Route System under the authority of the FHWA as part of a new Office of Livability.<ref>{{cite web |url = http://t4america.org/docs/062209_STAA_fulltext.pdf |title = Surface Transportation Authorization Act of 2009- Committee Draft |access-date = June 28, 2009 |archive-date = July 17, 2011 |archive-url = https://web.archive.org/web/20110717050949/http://t4america.org/docs/062209_STAA_fulltext.pdf |url-status = live }}</ref> In 2009, the FHWA published a new edition of the ''[[Manual on Uniform Traffic Control Devices]]'' that introduces a revised U.S. Bicycle Route shield. Compared to the 2003 edition, the new design swaps the bicycle symbol and route number.<ref name="AASHTO Moeur" />

In early May 2011, the first major expansion of the system was made. 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]].<ref name=ACA-release-May2011/><ref name=ACA-blog-May2011/>
* [[U.S. Bicycle Route 1]] now has an additional run from the state of [[Maine]] to [[New Hampshire]].
* [[U.S. Bicycle Route 1A]] is a sea-side alternate route for USBR 1 in Maine.
* [[U.S. Bicycle Route 8]] runs from [[Fairbanks, Alaska]], along the [[Alaska Highway]], to the [[Canada–United States border|Canadian border]].
* [[U.S. Bicycle Route 108]] runs from its parent route in [[Tok, Alaska]], to [[Anchorage, Alaska|Anchorage]].
* [[U.S. Bicycle Route 208]] follows the [[Haines Highway]] from the Alaska Marine Highway terminal in [[Haines, Alaska|Haines]] to the Canadian border.
* [[U.S. Bicycle Route 20]] runs from the [[St. Clair River]] through the state of [[Michigan]] to [[Lake Michigan]].
* [[U.S. Bicycle Route 87]] follows the [[Klondike Highway]] from the [[Alaska Marine Highway]] terminal in [[Skagway, Alaska|Skagway]] to the Canadian border.
* [[U.S. Bicycle Route 95]] follows the [[Richardson Highway]] from [[Delta Junction, Alaska]] to the Alaska Marine Highway terminal in [[Valdez, Alaska|Valdez]].
* [[U.S. Bicycle Route 97]] is entirely within Alaska, and it runs from Fairbanks, through Anchorage, to [[Seward, Alaska|Seward]].

In 2012, the FHWA approved the use of an alternative U.S. Bicycle Route marker design on an interim basis. The alternative design departs from the longstanding "acorn" shape in favor of a [[Reuleaux triangle]] placed over a green background.<ref>{{cite letter |subject = Information: MUTCD — Interim Approval for the Optional Use of an Alternative Design for the U.S. Bicycle Route (M1-9) Sign (IA-15) |first = Jeffrey A. |last = Lindley |recipient = Directors of Field Services, Federal Lands Highway Division Engineers, Director of Technical Services, Division Administrators |date = June 1, 2012 |access-date = August 20, 2018 |url = https://mutcd.fhwa.dot.gov/resources/interim_approval/ia15/ }}</ref> The FHWA gave 17 states interim approval to use the alternative design<ref>{{cite web |title = List of Approved Requests for Interim Approval |publisher = Federal Highway Administration |date = November 17, 2023 |access-date = December 19, 2023 |url = https://mutcd.fhwa.dot.gov/resources/interim_approval/ialistreq.htm#ia15 |archive-date = December 19, 2023 |archive-url = https://web.archive.org/web/20231219205804/https://mutcd.fhwa.dot.gov/resources/interim_approval/ialistreq.htm#ia15 |url-status = live }}</ref> before formally incorporating it into the ''[[Manual on Uniform Traffic Control Devices]]'' in 2023.<ref>{{cite book|title=Manual on Uniform Traffic Control Devices for Streets and Highways|edition=11th|publisher=Federal Highway Administration|location=Washington, D.C.|date=December 19, 2023|accessdate=December 19, 2023|page=1078|url=https://mutcd.fhwa.dot.gov/pdfs/11th_Edition/mutcd11thedition.pdf#page=1118}}</ref>

Across 2013, several other additions to the system were made.  After approval in 2012, signage for USBR 45 in Minnesota was completed in the summer. An expansion of USBR 76 into Missouri was signed in October, and both Tennessee and Maryland entered the system on November 5 with USBR 23 and USBR 50, respectively.<ref name="USBR50MD-23TN">{{cite press release |author = Adventure Cycling Association |url = http://www.adventurecycling.org/about-us/media/press-releases/new-us-bicycle-routes-approved-in-maryland-and-tennessee/ |title = New U.S. Bicycle Routes Approved in Maryland and Tennessee |publisher = Adventure Cycling Association |location = Missoula, MT |date = November 5, 2013 |access-date = November 5, 2013 |archive-date = November 10, 2013 |archive-url = https://web.archive.org/web/20131110010752/http://www.adventurecycling.org/about-us/media/press-releases/new-us-bicycle-routes-approved-in-maryland-and-tennessee/ |url-status = live }}</ref>  Florida has also begun planning on four bicycle routes, including its stretch of USBR 1 and USBR 90.<ref>{{cite web |url = http://www.sun-sentinel.com/news/palm-beach/fl-bike-trail-system-20131102,0,5315382.story |title = Florida Planning U.S. Bicycle Route for Long-Distance Bike Travel |date = November 10, 2013 |access-date = November 11, 2013 |archive-date = November 11, 2013 |archive-url = https://web.archive.org/web/20131111044940/http://www.sun-sentinel.com/news/palm-beach/fl-bike-trail-system-20131102,0,5315382.story |url-status = live }}</ref>
