**Deba-Mutriku Bridge** ::puente 
<div style="text-align: justify;">
The Deba–Mutriku bridge, inaugurated in 1866, marked a decisive improvement in coastal communications. For centuries, the two riverbanks had been linked by barges and a narrow bridle path, but the new bridge allowed carriages to cross without having to travel upriver to Sasiola. It quickly became an iconic feature of Deba’s urban landscape and is regarded as one of the most representative 19th-century bridges in Gipuzkoa.
The project was designed by engineer Antonio Cortázar, who opted for a robust stone structure supported by high-quality masonry and three large arches that ensured stability. The work was awarded to contractor Luis Emparan, and over 670 m³ of stone from the quarries of Deba and Mutriku were used. The bridge originally included a movable section built in 1866 by a Parisian company, consisting of two metal spans that could be raised by hand to allow vessels to pass at high tide.
Over the years, the bridge has undergone numerous repairs, reinforcements, and modifications —including the replacement of the movable section with a concrete arch in 1956— while resisting floods, erosion, and territorial disputes between Deba and Mutriku. After extensive restoration and rehabilitation works, the bridge was reopened in 2022, returning to the town one of its most distinctive historic landmarks.
