A viaduct for combined use of cars and electrical vehicles of the Metro has been constructed on the Park of the Town of Oporto. It is 228 m long and 16 m wide. It is divided into 8 spans and has 7 intermediate piles. The deck is a prestressed concrete, two-cell box. The shape of the viaduct was designed in order to minimize visual impact, specially to the pedestrians using the park.
