Africa-Press – Kenya. The Kenya National Highways Authority (KeNHA) has announced plans to partly close a section of the Southern Bypass in Nairobi this coming weekend.
In a notice on Monday, June 2, the Authority announced the traffic disruption would affect a section of the highway near the entrance of the China Road and Bridge Corporation (CRBC) camp, directly opposite the Nairobi National Park.
According to KeNHA, the disruption would last for eight hours, between Saturday, June 7 at 10pm and Sunday, June 8 at 8am.
The Authority further revealed that the disruption was to facilitate the installation of stress-strain sensors on the road surface.
“The Kenya National Highways Authority (KeNHA) wishes to notify the public that a section of the Nairobi Southern Bypass near the entrance of the CRBC Camp, opposite the Nairobi National Park, will experience a temporary traffic disruption,” KeNHA said in the notice. “The disruption follows the installation of stress-strain sensors on the highway pavement.
Stress-strain sensors are highly specialised instruments embedded into the pavement structure to measure how pavement materials respond to various physical forces.
These sensors are critical for authorities such as KeNHA in understanding the durability and structural integrity over time.
They achieve this by monitoring real-time data on how traffic loads, particularly from heavy vehicles, impact the pavement’s layers.
By collecting this data, KenHA hopes to be able to make informed decisions on the maintenance schedule, future upgrades and the construction standards of roads like the Southern bypass, which is heavily frequented by heavy commercial vehicles.
The disruption will, however, not affect both lanes of the Southern bypass, as according to KeNHA, only the outer single lane would be affected over a 10-metre stretch of the highway.
Motorists are thus advised to approach the section with extra caution and cooperate with the police and traffic marshals who will be on site during the brief closure.
In December 2024, KeNHA announced a similar closure of the Southern bypass to allow for the rehabilitation of the expansion joints of all the bridges along the section, as well as reconstruction of the concrete pavement of the Virtual Weighbridge
