The Nairobi expressway is a 27km road starting from the Mlolongo area and passing through JKIA to Westlands in Nairobi. The road was constructed under the public-private initiative in collaboration with the China Roads and Bridge Corporation and the government of Kenya.
The expressway was meant to ease traffic Jams that were evident on Mombasa Road throughout the day. Ever since it started operating, traffic on Mombasa Road has reduced drastically. Today, an airport transfer from JKIA to the city center takes approximately 15 minutes unlike in the past where it could take up to 45 minutes.
