A section of the roads within Nairobi will continue to experience traffic congestion as construction works continue.

KeNHA said there is notable progress in the construction of the operation and monitoring centre now at 98 per cent, which will help manage and maintain the road once it is operational.
“Over 4,000 people have been employed directly under the project across various departments,” the authority said.
KeNHA said traffic engagement remains a critical component of the project implementation to ensure ease of movement and safety for motorists.
The authority said various interventions have been put in place such as opening up of completed sections of the expressway to traffic to give way to works on the existing highway.
These, the agency said, include sections along Imara Daima to General Motors and Airtel headquarters
KeNHA said it has opened up the lanes that were previously closed at Syokimau and Mlolongo areas and improved two unidirectional U-turns at various points such as Mlolongo.
It said there is continuous watering of the construction sites to reduce dust.
KeNHA said angles at diversion points such as Gateway Mall were being widened to ease vehicle movement.
“KeNHA would like to appreciate all motorists on the patience excised during the implementation of these interventions.”
KeNHA said Haile Selassie-UoN roundabout will be restored on October 15.
The authority said the elevated section is 78.6 per cent complete.

"Test runs on the road will take place in March next year as we are confident that the contractors will have completed all works by February, " Transport CS James Macharia said on Wednesday.
Macharia noted that the government has cut the time frame for the Sh65 billion project by two years.
The Nairobi Expressway Project is a 27.1km road project beginning from Mlolongo through JKIA and Nairobi’s CBD to Westland’s area along Waiyaki Way.
The Expressway will have a four-lane and six-lane dual carriageway within the existing median of Mombasa Road, Uhuru Highway and Waiyaki Way as well as 10 interchanges.
The section between the Eastern and Southern bypasses will be a six-lane dual carriageway, while the section from to the Eastern Bypass and Southern Bypass to James Gichuru will be a four-lane dual carriageway.
It will be the first expressway in Kenya and the second largest toll road in Africa after the Dakar Toll Highway.
