What Happened Along the NKVE?
Heavy rainfall that continued past midnight on November 4 caused flash floods along several major roads in Shah Alam, including the NKVE.
According to PLUS Malaysia Berhad (PLUS), the affected section is located at KM9.1 between Shah Alam and Subang. Floodwaters made the stretch impassable, forcing the highway operator to close all lanes in both directions.
The latest update reported by Paul Tan on November 4 at 8.47am confirmed that the affected NKVE stretch remained closed to traffic.
The flooding also affected surrounding highway connections, creating additional disruption for motorists travelling through Shah Alam and nearby areas.
Motorists should note that highway conditions can change as floodwaters recede. The reported closure status should not be treated as confirmation of the current situation without checking the latest announcements from PLUS.
Which Highway Routes Are Affected?
The flooding has affected several important highway connections around Shah Alam, making it difficult for motorists to travel through the area.
1. NKVE at KM9.1 between Shah Alam and Subang
All lanes in both directions were reported closed due to rising floodwaters. Vehicles could not pass through the affected section.
2. Shah Alam Toll Plaza entrance
PLUS also reported flooding affecting the approach to the Shah Alam Toll Plaza, resulting in lane closures and traffic diversions.
3. Shah Alam Interchange on the ELITE Highway
The interchange connecting Seafield towards Setia Alam was also affected by flooding. However, subsequent updates reported that the affected lanes reopened at 6.43am.
4. Guthrie Corridor Expressway (GCE) connection
The route from the Guthrie Corridor Expressway towards the Shah Alam Toll Plaza was also reported closed due to floodwaters.
5. NKVE interchange ramps
PROLINTAS GCE reported that Ramps B, C and D at the NKVE interchange were closed following flash floods reported at approximately 5.42am.
Where Are Traffic Diversions?
Motorists travelling through the affected areas should follow the temporary traffic diversions introduced by PLUS.
Northbound traffic from Bukit Raja
Vehicles travelling northbound from Bukit Raja are being diverted towards the Setia Alam Toll Plaza.
Southbound traffic from Subang
Motorists travelling southbound from Subang are being diverted towards the ELITE Highway.
Traffic from Seafield towards Setia Alam
Motorists should refer to the latest PLUS announcements, as the Shah Alam Interchange section on the ELITE Highway was subsequently reopened following the earlier flooding.
Traffic from GCE towards Shah Alam
The connection towards the Shah Alam Toll Plaza was reported closed. Motorists should follow the alternative routes and directions provided by highway personnel.
These diversions may increase travel times, particularly during morning and evening peak hours. Motorists are encouraged to allow additional time for their journeys.
What Should Motorists Do During Flash Floods?
Flash floods can develop quickly, especially after prolonged or heavy rainfall. Motorists should prioritise their safety rather than attempting to reach their destinations through flooded roads.
1. Avoid flooded roads
Never attempt to drive through floodwaters, even if the water appears shallow. Water levels can be difficult to judge, and strong currents may affect vehicle stability.
2. Follow official traffic diversions
Pay attention to temporary road signs, electronic message boards and instructions from highway personnel. Do not attempt to enter closed sections.
3. Check traffic conditions before leaving
Check live traffic information and highway announcements before starting your journey. This can help you identify road closures and avoid unnecessary delays.
4. Keep a safe distance from other vehicles
Wet roads reduce tyre grip and increase stopping distances. Maintain a greater following distance to give yourself more time to react.
5. Postpone non-essential journeys
If your route is severely affected by flooding, consider delaying your journey until conditions improve.
Expert Tip
Before driving through an area affected by heavy rain, check traffic cameras and official highway announcements. A navigation application may suggest an alternative route, but always confirm that the alternative road is safe and passable before proceeding.
Common Mistake
Do not assume that a flooded road is safe to cross simply because other vehicles are attempting to pass through it. Water can hide potholes, damage vehicle components or cause an engine to stall. Turn around and find a safer route instead.
