Commuters using the Sungai Besi Expressway (BESRAYA) and New Pantai Expressway (NPE) are being urged to plan alternative travel routes during a scheduled overnight closure next month, as authorities prepare to host the IJM Allianz Duo Highway Challenge 2026, a major highway running event. The temporary shutdowns will remain in effect from 11 pm on August 1 through to 10 am on August 2, affecting multiple sections of these critical arterial routes that serve thousands of daily travellers across the Klang Valley.
On the NPE, the impact will be substantial, spanning two major segments of the expressway. The first closure zone extends from the KM1.8 point at Bulatan Kewajipan in Subang Jaya through to KM11 on the direction heading towards Bangsar, with both lanes blocked in either direction. A second affected stretch runs from the Kuchai Lama intersection at KM17 all the way to the Pantai Dalam Toll Plaza, likewise affecting traffic flow in both directions. Meanwhile, BESRAYA users will encounter restrictions from the Kuchai Lama intersection extending to Jalan Pandan 1 at KM21.9, with closures directed towards the Jalan Lingkaran Tengah 2 connection also affecting both directions of travel.
These closures have received formal authorization from multiple government agencies responsible for transport infrastructure and public safety. Chua Lay Hoon, chief executive officer overseeing operations for both BESRAYA and NPE, confirmed that the Works Ministry (KKR), Royal Malaysia Police (PDRM), and the Malaysian Highway Authority (LLM) have all granted their approval for the event. Such multi-agency sign-off underscores both the scale of the planned activity and the coordination required to minimize disruption to the travelling public during what will inevitably be a high-traffic period on these major routes.
The event itself represents a significant collaborative undertaking in Malaysia's running community and corporate sponsorship landscape. BESRAYA (M) Sdn Bhd and New Pantai Expressway Sdn Bhd, the latter operating as a subsidiary of IJM Corporation Berhad, have partnered with Allianz Malaysia Berhad to jointly organize the challenge. This level of partnership suggests an event of considerable scale and ambition, likely to attract substantial participation from both recreational and competitive runners seeking to leverage the unique setting of a highway closure for athletic purposes.
For motorists seeking to minimize inconvenience during the closure period, authorities have emphasized the importance of advance planning and early departure on the event day itself. The overnight timing of the closure—beginning at 11 pm—suggests an attempt to minimize impact on regular commuter traffic, though evening and early morning commuters should nonetheless prepare for significant delays or extended journey times. The strategic scheduling appears designed to contain disruption to off-peak periods, though those using these routes for early morning journeys should consider whether alternative arrangements are necessary.
To manage the flow of traffic and ensure participant safety during the event, a comprehensive traffic management strategy will be deployed across the affected areas. Traffic management officers, members of the Royal Malaysia Police, and technical support teams will be positioned at strategic points throughout the route to oversee operations. Their presence is intended to serve dual purposes: safeguarding the runners and other event participants against traffic hazards, whilst simultaneously managing the traffic congestion that will inevitably arise on the remaining open portions of these expressways as drivers seek to navigate around the closures.
Detailed information regarding viable alternative routes for drivers wishing to bypass the closure zones will be disseminated through the official social media channels maintained by BESRAYA and NPE. This approach reflects contemporary practice in transport communications, leveraging digital platforms to reach technologically-connected motorists efficiently. Those relying on these expressways are strongly encouraged to monitor these official channels ahead of August 1 to familiarize themselves with recommended detour options, which will likely involve a combination of secondary expressways and arterial roads depending on the driver's origin and destination.
Event participants and spectators attending the IJM Allianz Duo Highway Challenge 2026 are themselves advised to arrive early on the day and coordinate their journey planning carefully given the temporary nature of the closure and the likely concentration of event traffic. The counsel to arrive early reflects recognition that even with advance notice, the convergence of runners, spectators, support personnel, and the partial closure of major expressways could create significant congestion in surrounding areas. Those planning to participate or attend should consider arriving substantially before the event commencement to secure parking and navigate to the event site without being caught in last-minute traffic complications.
For those seeking current information and updates about the event itself, the organizers have directed interested parties to follow official social media accounts: the Instagram handle @ijm_highway_run and the Facebook page titled IJM Allianz DUO Highway Challenge Run. These platforms will presumably provide registration details, course maps, safety protocols, and real-time updates closer to the event date. Regular monitoring of these channels will be essential for participants and for drivers seeking updated information on the closure schedule and traffic management arrangements.
