Contralane Activated on GCE for Strathairlie Interchange

Contralane Activated on Guthrie Corridor Expressway for Strathairlie Interchange Construction

The Guthrie Corridor Expressway (GCE) has activated a contralane traffic arrangement to facilitate the construction of the new Strathairlie Interchange. A contralane is a temporary traffic management system where one direction of a divided highway is closed and traffic from both directions is diverted to the opposite carriageway, using a single lane in each direction separated by barriers. This arrangement is implemented by the expressway concessionaire, Prolintas, to allow safe construction of the interchange while maintaining traffic flow. The contralane is relevant to Malaysian commuters using the GCE, particularly those travelling between Shah Alam, Rawang, and the North-South Expressway (PLUS).

Key Facts

What Is a Contralane and Why Is It Used on the GCE?

A contralane is a traffic management technique where one carriageway is closed and both directions of traffic are shifted onto the remaining carriageway, separated by a physical barrier. On the GCE, this is being used to create a safe work zone for the construction of the Strathairlie Interchange while keeping the expressway open to traffic. The contralane on the GCE will be in place for approximately 12 months, from 16 July 2026 to mid-2027, with a reduced speed limit of 60 km/h through the work zone. According to Prolintas, the arrangement is necessary because the new interchange requires excavation and bridge works directly on the existing alignment. A statement from the concessionaire noted: “The contralane ensures the safety of both road users and construction workers while minimising disruption to travel times.”

How Does the Contralane Affect My Commute on the GCE?

Commuters using the GCE between Shah Alam and Rawang will experience a single lane in each direction for approximately 1.5 kilometres, with a reduced speed limit of 60 km/h. This is expected to add 5 to 10 minutes to travel times during peak hours. During the contralane period, the northbound carriageway is completely closed between KM 12.0 and KM 13.5, and all traffic uses the southbound carriageway with a concrete barrier separating opposing flows. Prolintas advises drivers to plan for additional travel time, especially during morning and evening peak periods. The expressway remains open to all vehicle types, but heavy vehicles are advised to use alternative routes where possible to reduce congestion.

When Will the Contralane Be Removed and the Interchange Completed?

The contralane is scheduled to remain active until the Strathairlie Interchange is fully constructed, which Prolintas estimates will take about 12 months. The Strathairlie Interchange is expected to be completed by mid-2027, at which point the contralane will be removed and normal traffic flow restored. The new interchange will provide direct access to the Strathairlie development area, reducing the need for U-turns and local road detours. Prolintas has stated that the project is on track and that any delays will be communicated via official channels and variable message signs along the GCE.

Who Is This Traffic Arrangement For in Malaysia?

This contralane directly affects daily commuters and logistics operators using the GCE, a key north-south corridor in the Klang Valley. The GCE connects the North-South Expressway (PLUS) near Rawang to the Shah Alam–Klang area, serving residents of townships such as Bandar Sri Damansara, Kota Damansara, and Puncak Alam. Approximately 45,000 vehicles use the GCE daily, according to 2025 traffic data from the Malaysian Highway Authority (LLM), and the contralane is expected to impact a significant portion of these users. The arrangement is particularly relevant for those commuting between Shah Alam and Rawang, as well as for trucks serving industrial areas in Bukit Beruntung and Kundang. Prolintas has also set up alternative route signage to divert traffic via the LATAR Expressway or federal roads during severe congestion.

Common Questions

Will the contralane affect my journey from Shah Alam to Rawang?

Yes, the contralane is located between KM 12.0 and KM 13.5, which is on the section between the GCE’s Shah Alam and Rawang ends. Expect a single lane in each direction and a 60 km/h speed limit, adding 5–10 minutes to your trip.

Is the GCE closed during the contralane period?

No, the GCE remains open. Only the northbound carriageway is closed for 1.5 km; both directions share the southbound carriageway with a concrete barrier. All exits and entrances in the affected zone remain accessible.

What should I do if I encounter heavy traffic due to the contralane?

Prolintas recommends using alternative routes such as the LATAR Expressway (E33) or the Federal Route 54 (Jalan Kuala Selangor) to bypass the work zone. Check real-time traffic updates via the PLUS app or Waze before departing.
