Traffic hotspots across Nairobi cluster along key commuter corridors and busy junctions that handle large volumes of vehicles daily.
Thika Road and the Pangani–Muthaiga area serve commuters travelling into the city from the northeast, while Mombasa Road carries traffic between Nairobi, industrial areas and Jomo Kenyatta International Airport.
Waiyaki Way is a major western approach into Nairobi, while Ngong Road connects southern and southwestern neighbourhoods to the city centre.
Other busy corridors include Uhuru Highway and Outer Ring Road, where traffic can build up as vehicles converge at major junctions.
The government and road agencies are implementing road upgrades, flyovers and intelligent traffic-management systems to improve traffic flow across the capital.
The Kenya Urban Roads Authority (KURA) says its Intelligent Transport System operates at 20 intersections along the Western Ring Roads, Ngong Road and eastern missing links.
Thika Road and the Pangani–Muthaiga Area
Thika Road is one of Nairobi’s major commuter corridors, connecting the city with areas to the northeast and parts of Kiambu County.
The road carries large volumes of private and public transport vehicles, with traffic building up at key junctions and on approaches to the CBD.

Muthaiga Roundabout connects Thika Road with roads serving Muthaiga and surrounding areas, making it a key point in the northern Nairobi traffic network.
Mombasa Road and the JKIA Approach
Mombasa Road is a major transport corridor serving Nairobi’s industrial areas, residential neighbourhoods and Jomo Kenyatta International Airport.
Traffic can build up around major interchanges and junctions as vehicles travelling towards the CBD, industrial areas and the airport converge.
The government is upgrading the James Gichuru Road–JKIA corridor to improve movement along the route and its connection to the airport.
Nairobi Waiyaki Way and Westlands
Waiyaki Way is one of the main western approaches into Nairobi, connecting the city to areas including Westlands and the wider Nairobi-Kiambu corridor.
KURA’s Intelligent Transport System covers sections of the Western Ring Roads and Ngong Road, with traffic signals, vehicle detectors, CCTV surveillance and a Traffic Management Centre used to manage traffic movement.
KURA also lists the Waiyaki Way–Redhill Link Road among its Nairobi road projects.
Ngong Road and Dagoretti Corner
Ngong Road is a major route connecting Nairobi’s southern and southwestern neighbourhoods to the city centre.
The corridor has several major junctions where traffic from different parts of the city converges.
KURA lists the dualling of Ngong Road between Dagoretti Corner and Karen Roundabout among its Nairobi projects. It also lists the Valley Road–Ngong Road–Nyerere Road interchange and Upper Hill overpasses.
In June 2026, the government commissioned the KSh3.8 billion Ngong Road–Naivasha Road Flyover to ease traffic congestion and improve connectivity in Nairobi, and President William Ruto commissioned the project on June 29.

Uhuru Highway and CBD Approaches
Uhuru Highway forms a major part of Nairobi’s central road network and connects several routes leading into and out of the CBD.
Traffic can build up at junctions with roads such as Kenyatta Avenue, Haile Selassie Avenue, and Bunyala Road as motorists enter or leave the city centre.
The volume of traffic on these approaches can increase during peak commuting periods.
Outer Ring Road
Outer Ring Road provides an important east-west connection across Nairobi, linking several residential and commercial areas without requiring all motorists to pass through the CBD.
The road connects with other major routes, including Thika Road, making its junctions important points for traffic movement.
KURA’s Intelligent Transport System expansion plans include the development of BRT Line 5 linking Thika Road to Mombasa Road through Outer Ring Road.
KURA also lists the Nairobi Outer Ring Road Improvement Project among its Nairobi infrastructure projects.
Jogoo Road and Eastern Nairobi
Jogoo Road is a major commuter route serving eastern Nairobi and connecting residential and commercial areas to the CBD.
Traffic pressure can increase at junctions where Jogoo Road connects with other major routes, particularly when vehicles converge during peak travel periods.
The wider eastern Nairobi road network is also included in KURA’s traffic-management and infrastructure programmes.
Muthaiga Roundabout
Muthaiga Roundabout connects Thika Road with roads serving Muthaiga and surrounding neighbourhoods.
Its position along the northern commuter network means that congestion on connecting roads can affect traffic movement around the junction.
The area is part of the wider northern Nairobi road network linking the CBD with Thika Road and roads towards Kiambu County.
Nairobi CBD Junctions
Several junctions within and around the CBD handle traffic from major commuter corridors.
KURA’s Intelligent Transport System uses traffic signals, vehicle detectors, CCTV surveillance and a central Traffic Management Centre to manage traffic at selected Nairobi intersections. The authority says the system is intended to improve mobility and reduce travel time.
Traffic conditions in Nairobi can also change when roads close for construction or other work, forcing motorists onto alternative routes.
Such diversions can increase traffic on roads that would otherwise carry lower volumes, making temporary congestion an important factor when assessing traffic conditions in the city.
Why Nairobi Traffic Keeps Returning
Traffic congestion is concentrated on major commuter corridors and junctions where large numbers of vehicles converge.
Road capacity, peak-hour traffic, junction bottlenecks, roadworks and temporary diversions can all affect how quickly motorists move through the city.
The government and road agencies are responding through road upgrades, flyovers and intelligent traffic-management systems.
KURA says it plans to expand intelligent traffic-management infrastructure in Nairobi, with its strategic plan targeting additional ITS installations at intersections and a Traffic Management Center for the metropolitan area.
