Residents in Port Talbot, Wales, have found unexpected benefits from living beneath an elevated section of the M4 motorway, which passes over their back gardens. Narelle Cowan and Aimee Lipley describe the concrete structure as a shelter from the elements, providing shade in hot weather and cover from rain, with Aimee calling it her 'free gazebo'.
The two-lane carriageway, which carries approximately 75,000 vehicles daily, is a relic of the 1960s freeway building boom. This particular stretch, opened on July 22, 1966, cuts through the Welsh industrial town, a stark example of motorways built close to homes. Narelle uses one of the M4's supporting pillars to hang her washing line, while Aimee notes the road deck offers protection for her daughter's toys and allows for shopping trips in the rain without getting wet.
Despite the proximity of the motorway, residents report that the noise is a 'background murmur' or 'ambience', with some hearing the nearby River Afan more clearly. Aimee also mentioned receiving 'rubbish' from vehicles above, such as cigarette ends and crisp packets. The area under the M4, initially built as the Port Talbot bypass, is described as a unique shelter, with children playing there even in the rain.
The construction of the M4 in Port Talbot involved demolishing homes and displacing communities. Historically, the old A48 road through the town was a congestion blackspot, and the motorway was seen as a symbol of progress, significantly reducing journey times. However, the disruption led to the 1973 Land Compensation Act, making it more expensive to build motorways close to urban housing.
Currently, a 50mph speed limit is enforced on the M4 section above these gardens, a measure implemented after Nitrogen Dioxide (NO2) levels exceeded legal limits. Residents feel this has reduced noise and pollution, with Narelle suggesting any smells were more likely from the nearby steelworks. Both residents also noted that living in this area has made property ownership more accessible.
