The Choa Chu Kang Bus Interchange is a local bus interchange which mainly serves the residential neighbourhood of Choa Chu Kang. Located at Choa Chu Kang Loop and connected to the Choa Chu Kang MRT/LRT Station and the Lot One Shoppers' Mall , the interchange is operated under SMRT. The bus interchange opened in 1990, making it one of the oldest surviving bus interchanges in Singapore to remain intact from remodification while still in service.
The bus interchange currently only has 12 services; 11 of which are SMRT Buses, the other a special free shuttle to Qian Hu Fish Farm. Typically passenger traffic is often very high in morning and evening peak hours.
Like other bus interchanges in Singapore, the interchange is still and was originally constructed as an open-air structure. However, the government has announced plans to redevelop the interchange and its surroundings in the Urban Redevelopment Authority's Master Plan in 2003. The interchange will hence be the seventh interchange to undergo air-condition upgrading works , after Toa Payoh, Sengkang, Ang Mo Kio and Boon Lay all five of which are currently in operation, and Serangoon and Clementi still under construction.
