This article, the first in a series of four on the possible effects of a fixed channel link, examines some of the options available. A recent report by the European channel tunnel group, prepared for the British and French authorities, recommends that bridge only or bridge-tunnel schemes are not viable at present. Of the five different forms of immersed and bored tunnel schemes that were investigated, the preferred solution was for a railway-only bored tunnel. This represents the lowest cost and would consist of a single passenger and freight line with a smaller service tunnel alongside. The merits of an alternative long-spanned bridge are discussed. It is argued that the carrying capacity of a single-line rail tunnel will soon become insufficient for the demand. It is suggested that a multi-span suspension bridge could be built with a central series of 2 km long spans supported by eight piers in the shipping lanes. Shorter spans would be incorporated over the shallower inshore areas.
