The A21 road is a major road in England that runs from London to Hastings, serving as a key route for commuters and tourists alike. Here are some detailed aspects of the A21:
Route Description
The A21 begins at its junction with the A20 in Lewisham, London. It then travels southeast through Bromley, Orpington, and into Kent. The road continues through Sevenoaks, Tonbridge, Tunbridge Wells, before descending into East Sussex towards Hastings on the south coast. Key sections of the route have been upgraded to dual carriageway or bypasses to improve traffic flow.
History
The A21 has a rich history:
- Pre-19th Century: The route was part of the old Turnpike roads system, which was crucial for the transport of goods and people between London and the southern coast.
- 19th Century: With the advent of the Railway, some sections of the A21 were less used, but it remained important for local traffic and trade.
- 20th Century: The road was significantly improved during this period. The construction of bypasses around towns like Sevenoaks and Tonbridge helped alleviate congestion.
- 21st Century: Recent improvements include the Kippings Cross to Lamberhurst bypass which opened in 2005, reducing travel time and improving safety.
Current State
Today, the A21 is a mix of single and dual carriageway sections:
- From Lewisham to Sevenoaks, the road is largely dual carriageway.
- The section between Sevenoaks and Tonbridge has been upgraded to a dual carriageway.
- Further south, the road alternates between single and dual carriageways with several roundabouts and traffic lights, particularly in and around Tunbridge Wells.
- The route through East Sussex is mostly single carriageway with some stretches of dual carriageway.
Traffic and Safety
The A21 experiences significant traffic, especially during peak commuting hours. There have been efforts to reduce accidents through road improvements, speed limits, and better signage. However, parts of the road are still considered hazardous due to its winding nature through rural landscapes.
Environmental Impact
The construction of new bypasses and road improvements has had environmental implications. Efforts have been made to mitigate these impacts through:
- Landscaping to blend the road into the surrounding environment.
- Wildlife corridors to allow safe passage for animals.
- Noise reduction barriers in urban sections.
