Thomson Road Grand Prix circuit

Thomson Road Grand Prix circuit was a former street circuit at Thomson Road in Singapore. It hosted races from 1961 to 1973 for automobiles under Formula Libre and Australian Formula 2 rules as well as for motorcycles. During the initial years, the main races for motorcycles and cars were 60 laps long. This was eventually refined into two separate races – a preliminary 20 lap event followed by a 40 lap event. The first Singapore Grand Prix of 1961 was won by lan Barnwell in an Aston Martin DB3S while the first Singapore Grand Prix of post-independence Singapore in 1966, which also ran to Formula Libre rules, saw Singaporean Lee Han Seng win in a Lotus 22. The final victory went to Australian Vern Schuppan in a March 722 in 1973.
