KENHA ANNOUNCES MAJOR TRAFFIC DISRUPTIONS ON KEY ROADS DUE TO CONSTRUCTION WORKS

The Kenya National Highways Authority (KeNHA) has issued several traffic advisories affecting key highways, including Mombasa Road, Mwingi–Ukasi Road, and Thika–Garissa Road. In a statement dated August 1, 2025, KeNHA cautioned motorists using Mombasa Road—particularly those traveling from Nairobi to Athi River—to drive carefully. The warning follows the interception of an overloaded truck that is currently blocking one lane of the road near Athi River. The Axle Load Enforcement Highway Unit Police are on-site managing the situation.

In addition to the obstruction, an accident at Maanzoni along the same route is further affecting the flow of traffic. Motorists are urged to cooperate with traffic officers and marshals as efforts to clear the affected sections continue. Separately, KeNHA has announced a four-month closure of a section of the Mwingi–Ukasi (A3) Road to facilitate construction work. In a public notice dated July 25, 2025, the authority stated that the road will be closed at KM 39+400 (Kwa-Vii) from Monday, July 28, to Wednesday, November 12, 2025, to allow for the installation of a box culvert.

To manage the disruption, KeNHA has developed a detailed traffic management plan, which includes designated diversion routes clearly marked for vehicles traveling toward Mwingi and Ukasi. Motorists are advised to observe all road signs and follow the directions of traffic personnel stationed in the area. Furthermore, KeNHA announced that the Kavenge (Mbakini) Bridge near Mbakini Centre on the Thika–Garissa (A3) Road will undergo maintenance and rehabilitation. As a result, traffic in the area will be disrupted for 106 days—from Saturday, July 26 to Saturday, November 8, 2025. The works will involve repairs to the bridge girders and deck.

KeNHA continues to urge all road users to remain patient, comply with traffic guidance, and stay updated on road conditions through official channels.
