M25

The M25 is a major road in the United Kingdom, forming a circular motorway around London. It is one of the busiest roads in the world, with an average of over 200,000 vehicles per day. The motorway was constructed in stages between 1973 and 1986, with the final section opening in 1986. The M25 is approximately 117 miles long and is owned and operated by the Highways Agency. It connects to several other major roads, including the M1, M23, and M20. The motorway is a vital link for commuters and businesses, providing a quick route around London. However, it is also a source of congestion and air pollution, with traffic often backing up for miles during peak times. The M25 is a crucial part of the UK's road network, but its impact on the environment and local communities is a subject of ongoing debate.
