UPDATE: Du Toitskloof Pass Temporarily Reopened to Ease N1 Congestion After Huguenot Tunnel Closure

Authorities have temporarily reopened Du Toitskloof Pass (R101) to ease heavy congestion on the N1 following the closure of the Huguenot Tunnel after a dramatic bus fire late on Friday night, 3 October 2025.

The incident occurred at around 23h30, when a passenger bus caught fire inside the tunnel. According to the South African National Roads Agency SOC Limited (SANRAL), no fatalities were reported, although one tunnel response official suffered minor smoke inhalation and was taken to hospital for observation.

“The bus wreckage has since been removed, but due to the damage caused to the tunnel infrastructure, the tunnel will remain closed until further notice for a full structural inspection,” said Mike Vinello-Lippert, SANRAL’s project manager. “This is to ensure the integrity of the tunnel, including the concrete roadbed, side linings, and ceiling. Other necessary infrastructure repairs will also be undertaken to fire detection equipment, lighting, and communications inside the tunnel.”

In response to the closure and growing traffic pressure on the N1, the Western Cape Department of Infrastructure has authorised the reopening of Du Toitskloof Pass under controlled conditions. The pass, previously closed for construction, is now open with two stop-and-go points in place. Motorists are advised to drive cautiously and expect delays.

“This arrangement will remain in place until the Huguenot Tunnel is reopened,” said Western Cape Minister of Infrastructure Tertuis Simmers, who issued the directive.

Authorities have also stressed that Bainskloof Pass is open to light motor vehicles only and must not be used by heavy trucks or buses due to low rock formations and safety hazards.

The reopening of Du Toitskloof Pass is expected to significantly reduce traffic congestion on the N1, especially for freight operators and long-distance buses travelling between Worcester and Cape Town. However, drivers should still anticipate longer travel times and plan accordingly.

“SANRAL thanks the tunnel operators and emergency services for their swift response, which prevented any serious injuries or casualties,” added Vinello-Lippert. “We will inform the public once the full extent of the damage and repair timeline is known.”
