The Dom Luís I Bridge, a must-see attraction in Porto

One of the highlights of Porto must be the Dom Luís I Bridge that spans the Douro River. It connects Porto and Vila Nova de Gaia. Pedestrians can cross to the other side on the upper or lower level of the bridge, and the upper level is an excellent place to enjoy the scenery on both sides of the Douro River. #Porto #D.
