The Pan Island Expressway is the oldest and longest expressway in Singapore. It is also Singapore's longest road. The expressway runs from the East Coast Parkway near Changi Airport in the east to Tuas in the west and has a total length of 42.8 kilometres (26.6 mi).

The expressways of Singapore are special roads that allow motorists to travel quickly from one urban area to another. Construction of the system was authorized when construction of the Pan Island Expressway began in 1962. All of them are dual carriageways with grade-separated access. They usually have three to four lanes in each direction, although there are two-lane carriageways at many expressway intersections and five-lane carriageways in some places. There are ten expressways. Studies about the feasibility of additional expressways are ongoing.
