C908 Cross Street Station 

Project Description

Contract 908 consists of Telok Ayer Station (180m) and running tunnels (275m) between Telok Ayer Station and Landmark Station which are located in principal route in the CBD. The construction was expected to worsen traffic congestion at peak hours. To mitigate it, 500m long temporary vehicular viaduct along Cross St. was constructed successfully by two shift (day and night) schedules to meet LTA’s need and reduce stakeholder’s inconvenience.
