gibralter bridge
The Gibraltar Bridge is a conceptual structure spanning the Strait of Gibraltar that would connect Europe to Africa.
Several engineers have advanced designs for a Gibraltar Bridge on various alignments and with differing structural configurations. Professor T.Y. Lin’s proposal for a crossing between Point Oliveros and Point Cires features a 14-kilometre length, deep piers, and 5000-meter spans, far exceeding the longest current bridge span.[2]
United States architect Eugene Tsui produced a revolutionary design which does not resemble any existing bridge and features an original floating and submerging concept while creating a three mile wide floating island in the middle of the Mediterranean Sea.[3]
Recent talk of a road bridge between Europe and Africa, spanning the Strait of Gibraltar, has centred on a slightly different type of suspension bridge.[4]
Although termed the "Gibraltar Bridge", it would be unrealistic for a tunnel or bridge to terminate in Gibraltar as the territory lacks the road and rail network to service such a structure.[5]
While a bridge between Europe and Africa could facilitate trade, some have questioned its potential effects on immigration.[6]
Futurist Arthur C. Clarke proposed a bridge across the Strait in his 1979 science fiction novel The Fountains of Paradise.

The Spanish and Moroccan governments have been jointly investigating the feasibility of a tunnel underneath the strait, similar to the Channel Tunnel between the UK and France.
The idea of a tunnel for petrol/diesel powered road vehicles has been discounted due to the currently insurmountable engineering challenge of ventilation to remove exhaust gases from automobiles from a tunnel some 14 kilometres (8.7 miles) long. A new three-year study for a railway tunnel was announced in 2003. The strait depth extends to 900 metres (3000 ft), and is about 14 kilometres (8.7 miles) wide at its narrowest point. The project would be financed by two publicly owned companies in Spain and Morocco.
The decision on building the tunnel is said to be near, as Swiss engineers finalize a study to determine if the tunnel is technically possible.[3]
