King Salman of Saudi Arabia has said that an agreement has been reached with Egypt to build a bridge over the Red Sea connecting the two countries.

The monarch made the announcement in televised comments on Friday - the second day of his visit to Cairo - after meeting Egyptian President Abdel Fattah el-Sisi, and before representatives of the two countries began signing investment deals.

It was not mentioned where the bridge would be built, but at the closest point - Nabq, just north of Sharm el-Sheikh, in Egypt, and Ras Alsheikh Hamid, in Saudi Arabia - the two countries are 16km apart.

The plan to build a joint bridge over the Red Sea at the entrance of the Gulf of Aqaba has been in the pipeline for several years.

Earlier proposals suggested the causeway would feature a railway line in parallel with the road lanes, integrating both country's proposed high-speed railway systems. In that plan, the causeway would pass through Saudi's Tiran Island, which would serve as a connection between the two countries.

For King Salman, it is about showing that Saudi Arabia and Egypt would stand together against outside interference, by which they mean Iran and its ambitions in the region.

For Egyptians, much more is at stake: The two countries are signing agreements including a multibillion-dollar deal whereby Saudi Arabia will finance Egypt's oil needs for the next five years and previous estimates for the bridge suggest a cost between $3bn and $4bn.

Besides the announcement, Saudi and Egyptian representatives signed 17 investment deals and memorandums of understanding.

Saudi Arabia is one of the top foreign investors in Egypt, with more than $8bn pledged late last year in sectors such as tourism, agriculture and information technology.
It has also promised to help the country meet its energy needs.

Egypt has faced years of political upheaval since the 2011 uprising that toppled longtime leader Hosni Mubarak, prompted a foreign-reserves crisis and slowed economic growth.

The country has since grown dependent on aid from abroad, although it says it seeks to wean itself off as soon as possible.
