Completed in 2012, the Viaduto Marão joined the 2011-built Despe-te que suas Bridge and the 1995 Rio Zêzere Bridge to become Portugal's highest span in a 3 way tie.  All are approximately 150 meters from deck to water.  With 4 main spans of 148 meters, this is arguably the largest viaduct ever built in Portugal.  The bridge is located on the western end of a new 30 kilometer highway extension that links up Amarante to Vila Real in Northern Portugal.  The new route bypasses an older highway with less turns and easier grades.

Marão Bridge
Viaduto Marão
Amarante, Porto, Portugal
492 feet high / 150 meters high
486 foot span / 148 meter span
2012

MaraoPierLineup2.JPG


Completed in 2012, the Viaduto Marão tied the 1995 Rio Zêzere Bridge to become Portugal's 3rd highest span after the Despe-te que suas and Corgo Bridges. The bridge is located on the western end of a new 30 kilometer highway extension that links up Amarante to Vila Real in Northern Portugal where motorists can cross into Spain. The new route bypasses an older highway with less turns and easier grades.

The huge, single cell rectangular box girder is 29.5 meters wide with gradual banking that changes from left to right as the bridge follows an S-shaped path as it crosses the deep Marão River valley.

Also on the new autopista is the gargantuan 220 meter high Viaduto Corgo and the 105 meter high Viaduto Sordo.
