What we are doing

EKFB are building a new bridge to carry the A423 over the HS2 railway line south of Southam.
To reduce the need for several months of road closures, we have designed a short section of new road, for traffic to bypass the construction area, whilst we build the approach roads to the bridge.

We have been building this new section of highway over the summer, and in September we will be ready to join it to the current road network. This requires a two-week road closure to join the roads together.

During the closure, we will be installing new speed limit signs. When we reopen the road, a 30mph speed limit will be in force between Ladbroke and Southam, until the new bridge is open to traffic.
