Special features

In London, the eastbound (London-bound) M4 carriageway has a bus lane from junction 3 until the elevated section. This lane caused some controversy when it was created.^[1] However, the bus lane has improved traffic flow onto the 2-lane elevated section which follows it.^{[citation needed]} There is some speculation that the original plan involved closing one lane from junction 3 to the elevated section to prevent congestion caused by the filtering of three lanes of traffic into two (the motorway is already temporarily down to two lanes at junction 3 because the left lane is exclusively for traffic leaving the motorway, so the effect of the bus lane is to make the 3-to-2 lane-transition seamless). Making the "spare" lane available for buses - and now taxis and motorcycles - was an afterthought.^[2] Bus Only Road Sign in Taiwan (This sign was also for bus lanes, now with a separate sign) Bus Lane Sign in Taiwan A bus (only) lane is a lane on a road restricted to buses, and possibly high occupancy vehicles, bicycles, emergency vehicles or taxicabs. ...

It has two of only three four-level stack interchanges in the UK, including the first UK example at the junction with the M5 (J20/"Almondsbury Interchange") and the other at the junction with the M25 (J4B). Both are impressive feats of engineering, particularly junction 4B which also has to make provision for a railway line passing beneath the M4. However, due to the nature of such junctions, drivers should bear in mind that it is impossible to make a U-turn at J20 or J4B. A stack interchange is a free-flowing junction between two or more roads that allows turning in all directions. ...

Near Junction 35, there is a stretch of the motorway that has a surfacing of porous asphalt that improves drainage and reduces noise. When driving in heavy rain conditions drivers notice a reduction in spray from other vehicles and improved visibility. This special surface was publicised in an episode of the BBCs Tomorrow's World programme. This was the site of the first trial of the new road surface when it was laid down in 1993^[3]. As shown in this cross-section, many older roadways are smoothed by applying a thin layer of asphalt concrete to the existing portland cement concrete. ...

Speed checks

Speed checks are carried out between junction 14 and junction 18 (in both directions). These are carried out by police camera vans situated on bridges over the motorway. These measure the speed of vehicles using laser detection equipment. The introduction of these measures proved controversial and resulted in a public protest, involving a go-slow of several hundred vehicles along the affected sections of the motorway during April 2005.^[4] A mobile speed camera is a term used in the United Kingdom to refer to a road vehicle fitted with speed camera equipment which can park at the side of the road, or on overbridges to monitor the speed of passing traffic. ...

Between Junction 34 and Junction 37, there are three bridges crossing over the motorway. These three bridges sometimes have mobile speed camera vans parked on them to catch speeding motorists on the motorway below. These bridges are located on fairly sharp bends in the motorway.

The section between junction 40 and junction 41 has a maximum speed of 50 mph (80 km/h), and is enforced by a permanent speed camera (Gatso), to be found near junction 41 (in both directions). A Gatso speed camera Gatso is a brand of speed camera manufacturd by the Dutch company Gatsometer BV.

Notes

During the construction of the section around Cardiff in 1980, junction numbers were set aside for intermediate interchanges that were not built at the time. 33 had been set for the link road to the west (A4232), 32 for the A470, with 31 intended for the A469 to Caerphilly, and 30 for the great "Hook Road" - a plan which was later shelved. Junction 30 was later added to serve the link road in the east, which will eventually form a ring road from junctions 33 to 30, via Cardiff Bay. Number 31 remains unused as of 2006, and there are no immediate plans to build a junction with the A469. Cardiff (English:  Welsh: ) is the capital, largest and core city of Wales. ...

Contrary to popular belief, junction 39 does exist. However, it consists of a single slip road completing the missing movement onto the westbound carriageway from the A48 at junction 38, thus there is no exit from the motorway at this junction. The A48 is a major trunk road in Britain. ...

Junction 41 refers to two different junctions in two different directions, their movements not complementary. In the westbound direction, 41 is indicated as a spur leading to the roundabout in Briton Ferry formerly known as 41A, and the original bridge over the River Neath, which would allow access onto the stretch of the M4 from junction 43 westward. In the eastbound direction, 41 is indicated as an exit-only route to the A48 towards Port Talbot. As a result, it is possible in both directions to travel almost 2 miles (3 km) in the same direction having both joined and subsequently left the motorway at "junction 41". Briton Ferry (Welsh: Llansawel) is a town in the county borough of Neath Port Talbot, traditional county of Glamorgan, south Wales It lies on the River Neath and Swansea Bay. ...
