Soon Lee Bus Depot is an SMRT Buses bus depot located in Jurong West, Singapore. It is the only multi-storey bus depot owned by Land Transport Authority and the depot itself consists of 3 decks for bus parking. This bus depot is also the starting point for Service 185 and Express 502, which go to Buona Vista and the Central Business District respectively. It replaced the former Jurong Bus Depot and Penjuru Bus Depot in 2002. Previously owned and operated by SBS Transit, Soon Lee Bus Depot was sold to the LTA in 2023 in preparation for SMRT Buses taking over the Jurong West Bus Package, which is managed from this depot. SBS Transit had their limited operations for Soon Lee Bus Park for services 30 (Boon Lay), 99 (Joo Koon), 174 (Boon Lay) and 198 (Boon Lay).
