Why fell trees last winter when no construction work has yet taken place?
Between Cardiff Gate (Jn 30) and Coryton (Jn 32), certain areas contain natural species which are protected by European and UK law. In particular to avoid tree and vegetation clearance in the spring which might have affected birds nesting and dormouse hibernation, clearance was undertaken from January 2007, following guidelines prescribed by the Countryside Council for Wales. Construction work will now follow along this section: north side first followed by south side in 2008.
