Again, A wrong example.

The only reason the Qatar Bahrain causeway was further delayed is political. Since day one, it was expected that the Saudis were secretly reluctant to allow such project as it would gradually limit their dominance over GCC road transport and the use of King Fahd Causeway. Add to that Qatari conservatives perspective that the causeway would allow what they call moral corruption & strengthen the Shiite minority inside the country.
In one way or another, this causeway will be constructed because of the will of both countries leaders. and you won't believe it if i tell you that winning the bid would play a vital role to have the "on hold" project to be recommence.
