Nairobi is set to tackle its notorious traffic congestion with five major infrastructure projects totaling nearly Ksh200 billion. These initiatives aim to significantly reduce daily commute times, which currently average 52.7 minutes, placing Nairobi second among African cities for worst traffic.

• The Kenyatta Avenue Viaducts, a Ksh6.5 billion project revived by President William Ruto’s government, will ease congestion at key roundabouts and is expected to save commuters 20-30 minutes during rush hour by December 17, 2026.
• The Green Park Pedestrian Underpass, a Ksh2 billion project, is nearly 90 percent complete and will remove pedestrian traffic from a crucial intersection, serving as a 24-hour transit hub.
• The Ngong Road – Naivasha Road Flyover, costing Ksh3.58 billion, will untangle traffic near Junction Mall, cutting up to 30 minutes from peak-hour journeys between Karen and the CBD by July 2027.
• The Nairobi Northern Bypass Expansion, a Ksh29.3 billion investment, will transform the bypass into a dual carriageway by 2028, reducing heavy-truck travel times by up to 40 percent.
• The Rironi–Mau Summit Road Upgrade, costing approximately Ksh160 billion, will dual and rehabilitate 175 kilometers of the A8 corridor by 2029, slashing travel times to western Kenya by over an hour during peak periods.
