This has been captured in the National Treasury’s Fourth Medium-Term Plan 2023-2027 which encapsulates the Bottom-Up Economic Transformation Agenda as a way for attaining inclusive growth. 

“The project aims to reduce the cost of transport and travel time within the city of Nairobi,” the Medium-Term Plan speaks of the project. 

According to the Plan, the lines will decongest traffic jams for motorists heading to Kitengela, Ngong, Kiambu and Kikuyu. 

The first BRT line will be a 27.4-kilometre stretch from traversing Limuru-Kangemi-CBD-imara Daima-Athi River-Kitengela.

BRT 2 will on the other hand cover Tala-Njiru-Dandora/Juja Road-CBD-Showground/Ngong Road-Ngong covering a distance of 12.2 kilometres. 

Of the third BRT line, it will commence at Mama Lucy Hospital passing through Donholm (Jogoo Road)-CBD-T mall-Bomasa-Karen-Kikuru. 

Upon completion, the third BRT line is expected to be the longest in the capital covering a distance of 30.8 kilometres. 

Lastly, the national government will construct a fourth BRT line from Ridgeways (Kiambu Road) passing through Balozi (Allsops) and ending at Imara Daima. 

The fourth BRT line is expected to cover a distance of 13 kilometres. 

According to the national treasury, all the BRT lines will be funded through Public-Private Partnerships (PPP). 

One of the successful infrastructure projects in Kenya that have been delivered through the PPP model include the Nairobi Expressway which has been key in decongesting Mombasa Road.
