The MP highlighted the critical condition of the A21, [K a strategic road connecting East Sussex's coastal communities to London and [3D [K and key economic centres. He emphasised that south of Pembury, the single-c [8D [K single-carriageway section fails to meet traffic demands, leading to safety [6D [K safety concerns, environmental issues, and socio-economic challenges for lo [2D [K local residents. Dr Mullan cited examples such as the primary school in Hur [3D [K Hurst Green being directly on the A21, posing daily risks to children's saf [3D [K safety during commuting hours. He also mentioned that rural single-carriage [15D [K single-carriageway A roads account for more than half of all fatal and seri [4D [K serious collisions despite carrying less traffic overall. Since 2020, £20 m [1D [K million has been invested in improving safety measures but these are seen a [1D [K as short-term fixes rather than addressing the root issue. Dr Mullan argued [6D [K argued that dualling the road would improve reliability, reduce vulnerabili [11D [K vulnerability to incidents, enhance economic growth opportunities, and impr [4D [K improve health and well-being for residents living along it.
