The County officer supervising the Old Road traffic management scheme has explained why these are taking place at this time of the year.

Unfortunately it was not possible to prepare the scheme to enable a summer start.  Carrying out this work solely at weekends would not help either.  Once the work commenced and the existing traffic signals were decommissioned the temporary signals need to be in place until the new permanent signals are ready to be commissioned.  This would extend this element of the works, together with the temporary traffic management for 10 weeks rather than the 4 envisaged and extend the overall programme by a further 6 weeks also.
