The 22km JKIA-Uhuru highway-Museum Hill-Gigiri road was expanded and completed in 2009. The work included the construction of an extra Lane on both sides of the road to reduce traffic snarl-ups. This is a plan to decongest Nairobi and includes expansion of trunk roads.

The project also includes expansion of the eight-metre 15km Outering Road that connects Mombasa and Thika roads to three-lane dual carriage-way. Kiambu Road has also been expanded. Other busy roads that need attention are Bomas of Kenya-Ongata Rongai, Jogoo and Juja among others.
