KeNHA Announces 5-Week Closure of Section of Thika Superhighway

Motorists using the busy Thika Superhighway have been notified of a temporary traffic disruption after the Kenya National Highways Authority (KeNHA) announced the closure of a section of the road for five weeks.

The planned closure is expected to affect motorists travelling from Nairobi towards Thika, with road users being advised to prepare for traffic diversions as construction activities take place.

In a notice issued on Sunday, November 8, 2026, KeNHA announced that the Thika-bound service lanes at Kihunguro along the Thika Superhighway will be temporarily closed from Sunday, November 15, to Sunday, December 20, 2026.

The authority explained that the closure will allow engineers and construction teams to undertake the pre-assembly of a bridge superstructure and its subsequent hoisting.

The works are part of ongoing infrastructure development activities along the busy highway corridor.

According to the authority, the temporary closure is necessary to provide a safe working environment for construction teams undertaking the bridge installation activities.

The assembly and hoisting of a bridge superstructure require specialised equipment and adequate space, making traffic management necessary during the construction period.

KeNHA has indicated that the affected section is located at Kihunguro, a busy area along Thika Road that serves motorists travelling between Nairobi and Thika.

The five-week closure is expected to affect daily commuters, public transport operators, private motorists and other road users who rely on the highway.

Thika Superhighway remains one of the most important transport corridors in the country, connecting Nairobi with Thika town and several other areas in Kiambu County.

KeNHA has outlined alternative routes to help motorists continue travelling towards Thika during the construction period.

According to the notice, Nairobi-Thika traffic will be directed through a diversion via Shell Petrol Station before rejoining the Thika Superhighway.

Motorists will also have the option of using a route behind Shell Petrol Station to reconnect with the highway.

The authority has urged drivers to follow the designated diversion routes and avoid entering restricted construction areas.

Motorists approaching Kihunguro are also expected to exercise caution and pay attention to traffic signs and instructions from officers managing the road.

The Kenya National Highways Authority has advised motorists to exercise extra caution around the construction area throughout the closure period.

Drivers have been encouraged to follow the proposed traffic management plan and cooperate with police officers and traffic marshals stationed along the affected section.

The authority’s directive is aimed at ensuring that construction activities proceed safely while minimising disruptions to road users.

Motorists travelling from Nairobi towards Thika may also need to allow additional time for their journeys, particularly during morning and evening peak hours.

The closure is scheduled to begin on November 15, 2026, and end on December 20, 2026, after which normal traffic operations are expected to resume, subject to completion of the works.

The announcement comes as infrastructure development continues along major roads in Kenya, with authorities undertaking construction and maintenance projects aimed at improving transport connectivity.

Motorists using Thika Superhighway have been urged to plan their journeys in advance and remain alert to traffic changes during the five-week construction period.
