The increased cost of the programme means that some projects will take longer to complete than originally envisaged. Nevertheless, the ambitious upgrade programme provided for in the NDP remains a valid strategic framework for the development of the national roads network. On the basis of a continuation of existing levels of funding, the NRA estimates that full completion of the major inter-urban routes could extend to 2009-10. However, route completion dates will depend on the funding levels available in the years ahead and on construction and land acquisition costs. The Government is seeking to ensure, within the constraints of available funding, that the pace and momentum of the national roads upgrade programme is maintained and, if possible, accelerated.
