ER198 - Upgrading of Woodsville Interchange

CPG Consultants was appointed to upgrade Woodsville Interchange and provided design consultancy services for the temporary road diversions, permanent traffic layout plans and highway alignments, both vertically and horizontally.


The works included three road tunnels and a flyover: a 255m long two-lane vehicular tunnel from Serangoon Road to Upper Serangoon Road, a 245m long two-lane vehicular tunnel from Upper Serangoon Road to Bendemeer Road, a 160m long one-lane vehicular tunnel from MacPherson Road to Bendemeer Road, and a 400m long one-lane flyover as a direct link to cater for traffic movement from Pan Island Expressway towards Kallang Way.


The existing at-grade road junction was reconfigured to improve overall traffic flow. Whampoa North Interchange was removed upon completion of upgrading works at Woodsville Interchange.
