The planned expressway is a dual-carriage motorway with initially four lanes, expandable to six lanes in the future. The road will be capable of supporting sustained traffic speeds of up to per hour and will have controlled access. ==History==

In February 2015, the Kenyan government hired PwC to conduct a feasibility study on the commercial and technical viability of the Nairobi–Mombasa Expressway. The PwC report indicated the highway was viable if the highway operator collected a toll that would be used to retire the private capital used to develop the expressway. Starting about that time as well, the government of Kenya, through the Kenya National Highways Authority (KeNHA), began detailed talks with Bechtel International on a public-private partnership (PPP) to design, fund, construct and operate the highway. ==Construction costs==

The cost of constructing this expressway is budgeted at US$2.1 billion. ==Timetable==

In August 2017, KeNHA signed a binding agreement with Betchel International, an American civil engineering and construction company to design, construct, and operate the proposed expressway. Completion of the first section was expected in October 2019, and the entire expressway was expected to open in 2024. In April 2019, the Business Daily newspaper reported that construction was expected to start in the second half of calendar year 2019. ==Developments==

In May 2024, president William Ruto, while on a state visit to the United States, witnessed the signing of an agreement between Kenya National Highways Authority (KeNHA) and Everstrong Capital the "United States infrastructure investment manager", to build this expressway at a budgeted price of US$3.6 billion. Funding is expected to be sourced from "pension funds, international investors, development agencies and Kenyan private investors". ==See also==
