A proposed causeway linking Qatar and Bahrain has been redesigned for the third time in the 12 years since the project was first mooted, it has been reported.
The revised project has an estimated cost of $2.9bn and is likely to have four vehicle lanes and two railway tracks, according to Gulf Daily News.
The 40km bridge was first announced in 2001 and was supposed to open to traffic this year, but has faced numerous delays, with the last mentioned opening date in 2015.
The causeway is now expected to be ready only shortly before the 2022 FIFA World Cup, which will be hosted in Qatar, as the decision to start building must be approved by governments in both Qatar and Bahrain.
When complete, travel times before Qatar and Bahrain will be reduced to approximately 30 minutes.
