Motorists using the Expressway have been warned of a five-day traffic disruption.
Moja Expressway in a statement on Wednesday announced that the traffic disruption is due to planned maintenance works at the Haile Selassie Toll Station Entrance B, situated adjacent to the Kenya Railways Museum
"The maintenance period is scheduled from Thursday, January 25, to Tuesday, January 30, during which traffic flow will be affected in one of the lanes," reads the notice.
Motorists using this route have been advised to anticipate potential traffic delays.
The company recommended that road users plan their journeys to minimize any inconvenience.
Additionally, Moja Expressway urged drivers to exercise caution when navigating the area undergoing maintenance.
"Please drive with caution around the maintenance area. Thank you for choosing the Nairobi Expressway," reads the notice.
The trial operation for the Nairobi Expressway Haile Selassie Exit Plaza started last week after being launched by Transport CS Kipchumba Murkomen set to launch it.
"We are pleased to announce that the trial operation of the newly completed Nairobi Expressway Haile Selassie Exit Plaza will commence on Saturday, January 20, 2024," Moja Expressway said.
The Haile Selassie Exit Plaza has five lanes which are meant to help ease traffic congestion between Capital and Haile Selassie Roundabout.
The new Expressway exit plaza offers smooth access to Nairobi CBD, Upper Hill, and Ngong Road.
Murkomen said the project with its five lanes will reduce congestion and improve traffic flow within the city.
“There are also plans to add two more lanes, from the current three, at the Museum Hill exit. The Nairobi Expressway is a shining monument to what private-public partnerships can do,” he said.
Murkomen said the project has reduced travel time from Jomo Kenyatta International Airport to Nairobi from two hours to 20 minutes at zero cost to taxpayers.
“The expressway employed 6,000 Kenyans during its construction, it now has 500 people employed permanently,” he said.
Murkomen said 200,000 subscribers have enrolled in the e-ticketing system in the past 19 months.
He said the road has carried 26 million vehicles, which is proof that it has demand.
“Besides the many socioeconomic benefits it has brought to our country, the Nairobi Expressway has facilitated the transfer of technology to Kenya," Murkomen said.
"Its smart traffic monitoring system, with a 360-degree view of the whole road, has enhanced security and emergency response. It will provide a good benchmark for the Intelligent Traffic System we have piloted and is ready for roll-out.”
The expressway seeks to decongest Mombasa Road, Uhuru Highway and Waiyaki Way but has experienced traffic since it was opened to the public.
The road has 11 tolling stations, 54 toll plazas, and 54 cameras, with 126 cameras inside the toll plazas.
The road is monitored with recordings being done at 30-minute intervals.
There’s a smart monitoring system that detects congestion, spillage, vehicle reversals, pedestrian crossing and emergencies.
The dual carriageway has 11 interchanges at Mlolongo, Standard Gauge Railway, JKIA, Eastern Bypass, Southern Bypass, Capital Centre, Haile Selassie Avenue, Museum Hill, Westlands, and James Gichuru Road.
The expressway, with 18.2km on the ground and 8.9km elevated, is a class A, four-lane dual carriageway with a design speed of 80km per hour.
