CAIRO/BEIJING -- For many Nairobi denizens, a newly built 27-kilometer expressway connecting the Kenyan capital to its main airport has been a life changer.
"It took two hours to reach the airport in heavy traffic before the highway opened, but now it takes just 20 minutes," said a 52-year old taxi driver, adding that he makes more money now that he spends less time stuck in traffic.
