I think that at the site of the old summer land place, there should be a three-way roundabout...up the hill, down the hill and the bridge out to England.
Oh yes...
They should build a bridge from Douglas prom all the way to where ever in England would be the best (cost versus best place for accesibility). Then the Steam Packet can eat shit and die because no one would use their service anymore. The Island, in the long run, would reduce its carbon foot print, because less aeroplanes need to fly, and maybe they could even stick a rail station on the top of the road to foot passengers can travel as well. It would run off solar and wind, and if the weather isnt that good, then there would be a carriage with treadmills and rowing machines, and cycle machines so people can workout, and generate electricity at the same time. Those passengers that do this get free travel. Also, they can hold running or walking races on it. Could be a new challenge..."Trans-Irish sea dash", could bring more money into the Island.
