Important Information:

Jonathan Wade, National Highways' senior project manager, acknowledges the disruption but emphasizes the long-term benefits for millions of users. While extreme weather in 2024 caused some delays, the core road improvements remain on schedule, with the extended completion timeline mainly affecting non-essential elements that won't impact most drivers.
