Two reasons turned the bridges into places of great importance. On the one hand, in the periods in which the river marked the border between the kingdoms of Navarre and Castile, they became places of undoubted military interest. On the other, they were essential for trade in a territory that has always been a producer of wines destined for sale in other areas. and therefore needed to ensure the availability of good communication channels.
That is why ensuring the river's Ford through appropriate steps has always been a concern. As a result of this situation, today we can contemplate a good number of historical bridges that are well worth our visit.
Let's start with the bridges that go beyond the Ebro River. Mantible The first dating of this bridge goes back to the 2nd century A.D. It seems to have been destroyed around the year 1099, although there are authors who delay their destruction at Muslim times. Your trace is fantastic. Although it continues in ruins today and only retains two bows and some stirrups, we can get an idea of the importance that this bridge had in the past and the importance of construction work.
Our next stop will be in San Vicente de la Sonsierra. We found here a long bridge of 248 meters in length. Its factory corresponds to different times as a result of the numerous breaks that the floods of the river provoked in its construction. Its origin is medieval, from this time conserves the first three eyes of the left margin. He suffered an important reconstruction in the 16th century. In the eighteenth century several avenues of the Ebro left the bridge unusable. In the nineteenth century again suffered new works that gave the aspect that today we can contemplate. In medieval times it had two defensive towers, one of which disappeared in the reform of the 16th century.
It is, together with the castle, one of the most representative elements of the locality. Its night lighting gives us a beautiful picture.
We are now heading to the known as Briñas Bridge. It's another important historical step. It is also of great bearing, with 154 meters of length. The first news of the existence of this bridge is dated in the 14th century. In the following century it had to be in bad condition and it was usual to allocate funds to its maintenance. This situation lasted in the successive centuries. In the nineteenth century finally reaches the configuration that we can see today. In this century would rise in the hill of the right bank a starry pillbox and different defenses that today we can not see remains. In the decade of the 40 of the last century, the bridge is built by which the road currently passes, leaving the historical without use. has been recently restored.
From the basin of the loose-jerk we will highlight three, that of Casalarreina, that of Cuzcurrita of the river heave and that of Cihuri.
The Casalarreina on the loose had its origin in a bridge of planks. In the eighteenth century the need to raise a more solid, given the importance that this route had for the wine trade that, from La Rioja, was heading towards the north. After different works that were destroyed by several avenues throughout the century, which forced the realization of continuous works, it would be at the end of the century when the bridge would be definitively concluded.
Located next to the Cuzcurrita and laundry room of the river heave we find this bridge of almost 50 meters in length. Its origin dates back to the 15th century. At the end of the next century it suffered major deteriorations as a result of a flood, forcing important reparations. New works were made necessary in the eighteenth century. In the next century, works would be addressed that would give it its final trace.
We will finish our visit on the bridge of the Priory of Cihuri, also on the river heave. It is a bridge of Roman origin and one of the most interesting and beautiful that we can contemplate. The current trace may date back to the 13th century. The bridge was owned by the monastery of San Millán. The surroundings are of great beauty. Next to it is the Priory building and a small neighborhood of wineries.
They are certainly not the only ones in the area. We can also visit the stone and Iron bridge in Logroño; that of Torremontalbo, on the Najerilla, that of ashtray and others of lesser size, but of great interest for the lovers of the civil engineering. You can find more information in the work of Arrúe and Moya catalogue of previous bridges to 1800.
