The statistic quoted by the Deputy is an estimate published by Dublin Chamber of Commerce in their February 1990 report, "Corridor to Competitiveness". They estimate that some 125,000 units of unitised freight whose natural market is the Central Corridor travels via the Northern Corridor. I accept this figure as a reasonable estimate. I would point out to the Deputy that it relates to both imports and exports.
This diversion of traffic is attributable to a number of interwoven factors which operate in favour of the Northern ports, including shipping costs, frequency and capacity of shipping services, port charges, lower costs of Northern Ireland hauliers and so on.
We have begun to tackle some of these problems through a major programme of investment in transport infrastructure agreed recently with the EC in the context of an operational programme on peripherality. This will be published shortly. In addition, the Government in conjunction with Irish export interests, are continuing to press the EC for assistance in financing mobile asset investment to offset the cost disadvantages which our unique peripherality and island nation status imposes on Irish exporters.
