For more on marking an answer as the "Best Answer", please visit our FAQ.My favourite 'bee in the bonnet'. The Humber Bridge is in debt to the tune of over �330m and struggles to keep up interest only payments.
The tolls are something like �2.50 each way (I'm guessing here) and therefore actively discourages movement of people on either side of the river (who traditionally detest each other by the way).
Woe unto you if you live on the south bank and need medical treatment only available in Hull. The only scheduled bus route between Hull and Grimsby is due to be scrapped in January.
Forget the bridge and lower the protcullis!! There again, being southerners they probably deserve the aggro!!!
Of course this is based on speculation rather than fact, but using historical data (and without a particular design concept to work to) and assuming it is car only not rail.
Using the Millau Viaduct as a cost model (�400 million euros) and allowing for a general rise in steel prices and skilled labour being available in the UK, I would estimate a cost in the region of �120,000 per metre of road length. I imagine that the length would be about 10 miles (?) so at 16km x �120k you wouldn't get much change out of �2.0 billion. On top of this you would need to add costs of infrastructure to support it including toll booth plazas. If you imagine that you average 1,000 cars a day to recoup the capital cost (alone) over 100 years you would need to charge around �55 per car per crossing. I can't see it happening!
In the same token of broad brush back of a fag packet estimates, a tunnel using the channel tunnel cost (about �8.6 billion) the cost of a tunnel from Portsmouth to Cowes would cost around �2.8billion and using the same (100 years / 1,000 cars) data above, cars would need to be charged around �76 per journey. To recoup the capital cost of the build.
Of course I forgot to allow a for inflation for the tunnel, so it could be well over �3bn.
Anyway, the Humber Bridge cost �98m construction cost, but at opening in 1981 the debt with loan charges was nearer to �151m (about �400m equivalent today). The government decided to subsequently pay off the Humber Bridge and paid over �300m (about �1bn today).
The bridge spanned just about 2.2km and had 27,500 tonnes of steel. The steel alone at todays prices would total more than �100m in todays market.
