Why was the CTE widened?

As it provides access to towns such as Ang Mo Kio, Hougang, Sengkang, Punggol, Yishun, Sembawang and Woodlands, the CTE is heavily used and operates at full capacity. The widening works will help to ease the current traffic congestion and meet the anticipated increase in traffic as these towns develop further in the next 10-15 years.


How will the road widening works benefit motorists?

With traffic in these areas expected to grow in the next 10 to 15 years, improvements in CTE will:

  • increase traffic capacity on CTE with 4 uninterrupted continuous lanes from Bukit Timah Road to Yio Chu Kang Road
  • provide a smoother travel experience along the CTE
  • offer seamless travelling via flyovers
  • enhance commuter facilities with covered pedestrian overhead bridges and ramps
