Thomson Road Grand Prix circuit 2.5

The Thomson Road Grand Prix circuit was a former street circuit on Thomson Road in Singapore. It hosted races from 1961 to 1973 under Formula Libre and Australian Formula 2 rules, and hosted the Singapore Grand Prix from the country's independence in 1966. During the initial years, the main Motorcycle and Car Grand Prix lasted 60 laps, although 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 Ian Barnwell in an Aston Martin DB3S while the first Singapore Grand Prix of post independent Singapore (also run to Formula Libre rules) saw Lee Han Seng win in a Lotus 22 Lotus-Ford. The final victory went to Vern Schuppan in a March-Ford in 1973.HistoryIn 1960, a Grand Prix was devised as part of the "Visit Singapore – The Orient Year" campaign" to attract tourists to the region. At that time, Singapore lacked a formal racing circuit, and as a result, a new circuit had to be found. The initial suggestion for a street circuit that ran through Thomson, Whitley, Dunearn and Adam Roads was found to be unfeasible due to the massive traffic disruption it would cause to residents. After consideration of other existing circuits, it was decided that a new circuit would be created along the old and new Upper Thomson Road.
