The tunnel digging venture says it will build "a cutting-edge passenger transport tunnel project" that's "4 miles (6.4km), comprising four stations, linking the Dubai International Financial Centre and Dubai Mall."

Musk's previous business dealings with Dubai include a $700 million from a secretive VC firm to fund his acquisition of Twitter.
