McCallum Street is a one-way street through the Financial District and Chinatown of Singapore. It starts at Shenton Way and ends at the intersection with Telok Ayer Street, from where it continues as Amoy Street. The traffic direction is one way from Shenton Way to Cecil Street; it is in the opposite direction from Telok Ayer Street to Cecil Street.
Named after Major H.E. McCallum, the government engineer involved in the land reclamations of 1890's, McCallum Street was created following the land reclamation that extended the shoreline from Robinson Road to Raffles Quay. There is a possibility - but not conclusively verified - that MaCallum Street, Penang, was also named after him.
The Shenton Way section of McCallum Street is characterized by skyscrapers. A pedestrian overpass is located right at the junction of Shenton Way to McCallum Street. As you head west on McCallum Street, you pass a number of small lanes such as Maxwell Link and Boon Tat Link. They appear almost like gorges hemmed in by concrete canyons.
