Gone Fishin'
With the UK's under developed and crowded motorway network plus all the trouble with upgrading roads up to motorway specs, and building new motorway regarding the Green & NIMBY lobbies, how doable would it be to put new and existing motorways underground?
What I envisage is a TBM with a bore width of 200ft allowing a motorway to be dug with 6 lanes (10ft) each either side of a 10ft refuge plus a 25ft hard shoulder for safety plus slip ways at junctions up to ground level traffic.
Could this be done?
Could a TBM be built with this bore width?
Would it be efficient enough to use in regards to energy use?
Would ventilation be an issue with exhaust fumes?
