Non-motorized access on freeways may allow or restrict pedestrians, bicyclists and other non-motorized traffic to use a freeway. Such roads are public ways intended primarily for high-speed travel over long distances, and they have resulted in highways in the United States with engineering features such as long sight-distances, wide marked lanes and the absence of cross traffic. These provide faster and safer travel, at least for vehicles driving at similar speeds.

Freeways are usually limited to motor vehicles of a minimum power or weight; signs may prohibit bicyclists, pedestrians and equestrians and impose a minimum speed. It is possible for non-motorized traffic to use facilities within the same right-of-way, such as sidewalks constructed along freeway-standard bridges and multi-use paths next to freeways such as the Suncoast Trail along the Suncoast Parkway in Florida.

European Union[]

In the countries of Western and Northern Europe with relatively high bicycle share like the Netherlands, Denmark, Belgium and Germany, cycling on motorways is not a topic in the debate: cycling is not allowed on official motorways, and generally forbidden with road signs on all look-alikes.

In those countries it has no practical use, and effort is put in building an independent cycling network, crossing no entrance and exit ramps of arterial roads and expressways. Some sections of the cycle networks of these countries are adjacent to (but separated from) a motorway, but those are exceptions.

United Kingdom[]

In countries such as the United Kingdom and Germany, the difference between a normal road and a freeway-class road (motorway or autobahn) is the restriction of low-speed traffic. Many roads are built to freeway standards but are not legally freeway-class roads for this reason. Indeed, some freeway-class roads are downgraded for short stretches where no alternative exists, to allow low-speed traffic; examples in the UK include the Dartford Crossing^{[note 1]} (the furthest downstream public crossing of the Thames), and the former Cumberland Gap, as well as sections of the A1 not yet designated A1(M), various lengths of the A5, and the entirety of other important and near-motorway-standard links such as the A14, A34, A38, A42, A50, and A55 road, long stretches of which carry 70 miles per hour (110 km/h) speed limits. The reasons for such designation vary—physical lack of space (A55), restricted budget (e.g. A42; a full-standard motorway would have been more expensive than an A-road; a motorway with additional service roads further still), or because of legislative or political wrangling (easier to have A-road construction or upgrade authorised and accepted than a more emotionally charged "motorway scheme", and does not require issuing of Special Road orders).

United States[]

In some US jurisdictions, especially where freeways replace existing roads, non-motorized access on freeways is the rule. Different states of the United States have different laws. Cycling on freeways in Arizona may be prohibited only where there is an alternative route judged equal or better for cycling.^[2] Wyoming, the least populated state, allows cycling on all freeways. Oregon allows bicycles except on specific urban freeways in Portland and Medford.^[3] U.S. Route 23 in Ohio has a speed limit as high as 65 miles per hour (105 km/h) but isn't legally a freeway-class road since it has no disclaimers saying that low-speed vehicles are prohibited; it also has at-grade intersections like expressway-class roadways.

Freeway travel eliminates most collision points that are caused by turning or crossing at intersections, save at entrance and exit ramps. An analysis of crashes in Arizona showed no safety problems with cycling on freeways. Fewer than one motor vehicle-bicycle crash a year was recorded in the 1990s on nearly 3,200 shoulder kilometres (2,000 mi) open to cyclists in Arizona. The study did not attempt to establish how common cyclists are on Arizona freeways or whether they are aware that they can legally cycle on some freeway stretches; accidents were also noted on stretches where cycling was forbidden.^{[4][unreliable source?]}

U.S. states permitting bicycle use on interstate highways[]

Most U.S. States with low population densities commonly permit bicycle use on interstate freeways outside urban areas. Additionally, some states permit bicycle use on at least some interstate routes specially designated to accommodate bikes.

Bike freeways[]

Bike freeways (also known as cycling highways) are direct, long-distance cycle tracks separated from motorized traffic and with almost no big intersections or delays, intended for utility cycling. In countries like the Netherlands and Belgium (Flanders), they are built connecting city and town centers, e.g. adjacent to railroads.
