A limited-access road or controlled-access road is a road to which access from adjacent properties is limited in some way. It can mean anything from a city street to which the maintaining authority limits driveway access to a freeway (or other equivalent terms). The precise definition of these terms varies by jurisdiction.

Road maps generally use either term to indicate to indicate freeway standards.
In the United States, the Manual on Uniform Traffic Control Devices (MUTCD) only uses "full control of access" or "partial control of access" (for freeways and "expressways" - roads with some intersections - respectively). Some states use "controlled access" to mean a higher standard than "limited access", while others reverse the two terms.
In the U.S. state of Illinois, a freeway refers to a highway with fully controlled access — there is no access to a freeway except via interchanges. An expressway refers to a highway with partial-controlled access; at-grade intersections with driveways and low-volume local roads, and interchanges with "marked" routes (Interstates, U.S. Routes, or Illinois Routes) and high-volume county roads. In Illinois, farming equipment is prohibited on freeways but allowed on expressways. Like a freeway, commercial development directly off an expressway is prohibited. Access to commercial properties near expressways is granted via frontage roads.

The concept of limited-access roadways started with the parkway system in the state of New York, circa 1907. The New York State Parkway System was a series of high speed (30 Mph) four-lane roads that were created to provide a scenic way in to, out from, and around New York City. These highways allowed no driveway cuts, but did have intersections for most of the streets they crossed. They also provided rest areas along the way that offered fuel and restrooms. The road ways were typically divided by a wide landscaped median.
The concept evolved into uninterrupted arterial roads that are commonly known as expressways, motorways, or parkways, among other names both in the US and other countries.

A controlled-access highway is usually a step up from a limited-access highway. These usually feature grade-separated interchanges and frontage roads with ramp access.
When toll booths are placed along the road, they are called toll roads, tollways, or turnpikes, among other names both in the US and other countries.
Dual carriageways (or divided highways) with long intervals between at-grade intersections and no private access may also meet the criteria of being "controlled-access." Such roads may also be called expressways.
One such example is the "Marquette Bypass" on U.S. Route 41 in the Upper Peninsula of Michigan. The bypass is a expressway in terms of signage, although it has traffic lights at the junctions.
