On 2 November 2002, under Manuel Frasquilho's tenure as president, the Green Line's extension from Campo Grande to Telheiras opened. In 2004, the network opened its first extensions outside the geographical limits of the city: first, in March, with the expansion of the Yellow Line from Campo Grande to Odivelas (which included five new stations, two of which are aboveground); then, in May, the Blue Line was extended from Pontinha to Amadora Este. Later that year, construction of the Red Line segment between Alameda and São Sebastião began.
