The Woodsville interchange is an important traffic intersection along the PIE corridor in Singapore where East West and North South traffic meet. In order to cater for increasing traffic, demand the existing traffic intersection is being upgraded. The major element of this work is construction of a tunnel to allow the North South traffic to pass unhindered below the busy expressway interchange. When completed, it will cut travelling time through the junction and increase road capacity to 11,000 vehicles per hour.
