Two-lane freeway
Encyclopedia
A two-lane expressway is an expressway
with only one lane in each direction, and usually no median barrier. It may be built that way because of constraints, or may be intended for expansion once traffic volumes rise. The term super two
is often used by roadgeek
s for this type of road, but traffic engineer
s use that term for a high-quality surface road. Most of these roads are not tolled.
A somewhat related concept is a four-lane undivided expressway. This is much rarer; an example is some sections of U.S. Route 101
in northern California
.
compromise or as a way to overcome problems constrained from highway reconstruction when there are four lanes or more. If the road is widened, the existing road is typically allocated to traffic going in one direction, and the lanes for the other direction are built as a whole new roadbed adjacent to the existing one. When upgraded in this manner, the road becomes a typical freeway. Many two-lane freeways are built so that when the road is upgraded to a proper divided freeway, the existing overpasses and ramps do not need reconstruction.
A super-2 expressway is a high-speed surface road with at-grade intersections, depending on the common usage of the term expressway in the area. By this definition, Super-2s can be considered the first stage of project which is expected to become a full freeway, with the transportation authority owning the land necessary for the future adjacent carraigeway. At-grade intersections exist but there is sufficient land to replace them with interchanges. In some US states, a super-2 expressway is simply referred to as a super-2, regardless of whether it is fully controlled-access or not.
When an undivided freeway has four lanes, it is known as a super-4, though these are an oddity as most multi-lane freeways are divided, due to potential accidents from high-speed traffic crossing to the opposing side. Highway 27 directly north of Highway 401 in Toronto, Ontario is an example of a super-4 freeway by this definition, as it has four lanes of undivided traffic, and is fully controlled-access with interchanges and service roads to provide access to property in the area.
A super-4 expressway is a multi-lane divided highway with at-grade intersections, although the highway will become a full controlled-access freeway if the intersections are replaced with interchanges. A super-4 may have formerly been a super-2 that has been twinned, although such instances of super-4 intermediaries are rare as super-2s are often upgraded right away to full freeways. Highway 40 in Ontario is a super-4 expressway between Highway 402 and Wellington St., and from Indian Rd to Courtright. The remaining sections of Highway 40 are super-2 expressways. Other super-4 expressways include the Hanlon Parkway
in Guelph and the Black Creek Drive
in Toronto, both which have sufficient right of way to allow for interchanges and overpasses to replace the at-grade crossings.
When a super-2 expressway is converted to a 4-lane divided freeway, conversion artifacts such as double yellow lines, or broken yellow lines in passing zones are usually cleanly bestowed in favor of more consistent road marking for 4-lane divided expressways.

was initially a two-lane toll expressway before being upgraded to a full expressway in 1997. While the full four-lane divided toll expressways are more favored in recent years due to their higher traffic capacity, a few two-lane expressways do exist, such as the Kempas Highway
and the North Klang Straits Bypass
. These expressways, however, only have partial access control with at-grade intersections commonly available like most other federal and state roads. Nevertheless, these two-lane highways are still classified as "two-lane expressways" as they are maintained by highway concessionaires, namely PLUS Expressways Berhad
(Kempas Highway) and Shapadu (North Klang Straits Bypass).
The first true two-lane expressway with full access control
is the section of the Senai-Desaru Expressway
