The Sh62 billion project, which started late last year, will result in Kenya’s first double-decker expressway and is financed under the public-private partnership (PPP) model.
The China Road and Bridge Corporation (CRBC) will build the 27.1km road linking the Jomo Kenyatta International Airport (JKIA) to the Nairobi-Nakuru highway in a maximum of three years.
The project is expected to reduce the heavy traffic on Mombasa Road, which usually starts from Mlolongo and goes all the way to the city centre.
Motorists should brace for major traffic congestion and delays as sections of Mombasa Road and Uhuru Highway have been shut for construction of the Nairobi Expressway.
In a statement on Thursday, the Kenya National Highways Authority (KeNHA) the construction will be limited to the central median of Mombasa Road.
