MacRitchie Viaduct (sometimes also called Lornie Viaduct) is a viaduct in Thomson, Singapore that was built on top of Lornie Road and Thomson Road, with its extension also above Braddell Road. The viaduct is built to allow residents living in the Eastern, Central and Western part of Singapore a high-speed access between the east and the west for the residents who wants to travel from the east to the west or vice versa. The extension of the viaduct was opened on 24 August 2008, and is the first flyover to be constructed over an existing flyover, the Marymount Flyover. The extension is also part of the Outer Ring Road System, allowing motorists travelling between Queensway and Bartley Road to bypass the city area.
Extension project
As part of the Outer Ring Road System, the Land Transport Authority (LTA) widened the existing viaduct and constructed a pair of dual two-lane vehicular viaducts from Braddell Road to join the existing MacRitchie Viaduct. It provides a direct link between Lornie Road and Braddell Road, allowing motorists to bypass the traffic light junctions at Braddell Road, Thomson Road and Lornie Road. The extension project also increased the traffic capacity in the area.
Sago Kogyo was awarded the civil works contract by the LTA for the construction of this extension project. Worth about S$34.4 million, the contract covers the extension project; includes widening of the existing viaduct and construction of the extension of the viaduct from Braddell Road to the widened MacRitchie Viaduct. The contract also includes the widening of existing at-grade roads: Lornie Road, Braddell Road and Thomson Road. Additionally, the civil works included the construction of four new bus shelters and one new pedestrian overhead bridge with covered walkways to the nearest bus shelter.
The Land Transport Authority worked closely together with the National Parks Board to minimise the need to remove trees around and in the construction site. Despite the efforts, some trees were affected and had to be felled.
