The first enlargement project was approved by referendum in Basel in 1960 and, over the following decades, the terminals and runways were continually extended. The north–south runway was extended further to 3,900 metres (12,800 ft) in 1972. In 1984, an annual total of 1 million passengers was reached. In 1987, the trademark name EuroAirport Basel–Mulhouse–Freiburg was introduced.[6]
In 1992 a total of 2 million passengers used the airport. By 1998, this number rose up to 3 million
