A
two-lane freeway or
two-lane expressway is a
freeway or expressway with only one lane (road) 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 roadgeeks for this type of road, but traffic engineers use that term for a high-quality surface road.
A somewhat related concept is a
four-lane undivided freeway. This is much rarer; an example is some sections of U.S. Route 101 in northern
California.
Justification
Two-lane freeways are usually built as a temporary solution due to lack of funds, as an environmental movement 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.
List of two-lane freeways
Australia
- In Melbourne, Victoria (Australia) the Mornington Peninsula Freeway, Metro 11, is a two-lane freeway between the interchange with Jetty Road and the interchange with Boneo Road.
- In Brisbane, Queensland the Cunningham Highway, National 15, is a two-lane freeway between Warwick Road and Ripley Road, After Ripley Road the Cunningham Highway is grade separated until it meets the Ipswich Motorway, M2.
- In north-eastern Tasmania, the Bass Highway (Highway 1 (Australia)) is at 110km/h with freeway conditions, but with some sections having only two lanes.
- On the Sunshine Coast, Queensland in Queensland the Sunshine Motorway, State 70, is a two-lane freeway between the Bruce Highway and Nicklin Way, and again between Maroochydore Road and Emu Mountain Road (although it has a roundabout in this section).
- In Townsville, Queensland, Queensland, the future Townsville Ring Road is planned to be the future route of Highway 1 (Australia) through the city. The first stage of the project, the Douglas Arterial Road opened in April 2005, making it the first freeway north of the Sunshine Coast . Once all four stages are built, it will be designated as the M1.
- The suburb of Blue Haven (Near Doyalson) on the Central Coast, New South Wales in New South Wales, on the so-called "Motorway Link Road" between the Pacific Highway (Australia) and the F3 Freeway, is also another example of a two-way freeway - that has a speed limit of 100km/h. See .
New Zealand
- Linking the cities of Napier, New Zealand and Hastings, New Zealand is the two-laned Napier - Hastings Motorway.

- The city's main southern access road, the Dunedin Southern Motorway, also has a short one-kilometre section which is only two-laned.
Europe
- In a few European countries (like Germany and Switzerland), many rural highways have been converted into two-lane freeways.

In German language this type of road is called an Autostrasse.

According to a toll collector, this Super-2 is scheduled for an upgrade to a full toll freeway (four lanes, two in each direction) by sometime in 2008. Eventually, this freeway may be constructed all the way to San Luis Rio Colorado, replacing the existing four lane undivided highway, MEX-2.
