Super cube problem for Dublin Port Tunnel

More than half of the trucks operating in Britain won’t fit in the Dublin Port Tunnel when it opens next year, new research has shown.

The Transport Research Laboratory surveyed 80,000 trucks on the M3, M4, M5, the A14, and A4 using special laser equipment designed to measure vehicle heights.

The survey concluded that nearly 50 per cent of the trucks were running with an operating height of 4.9 metres, a full 25cm taller than the operating height at Dublin Port Tunnel.

The survey concluded that more and more UK- based trucks are running close to the 5.03 metre height for motorway and road bridges.
