The North Channel (Known in Scottish Gaelic and Irish as: Sruth na Maoile) is the strait which separates Northern Ireland from Scotland.The deepest part is called Beaufort's Dyke. The Channel connects the Irish Sea with the Atlantic Ocean. It is crossed by a large number of ferry services. In 1953, it was the scene of a serious maritime disaster, the sinking of the ferry Princess Victoria.Unionist Northern Ireland political leaders for decades lobbied the UK government to construct a rail-link tunnel under the North Channel, the better to integrate the troubled province into the larger United Kingdom. In August 2007 the Centre for Cross Border Studies proposed the construction of a 34 km (21 mi) long rail bridge or tunnel, estimating that it may cost approximately £3.5bn.
