It was noted in the national development plan that in 20 years two thirds of national primary roads and just over one third of national secondary roads would fail to deliver the minimum level of service considered desirable to maintain an average speed of 60 miles per hour – 70 miles per hour on dual carriageways – on inter-urban journeys. This is proof that the Government is not committed to the completion of national primary routes, not to mention the secondary routes programme, within the envisaged timescale. If work in this area was completed on time, it would ensure that major towns throughout the country have the best possible access to ports and airports which would make them attractive to inward investment.
