Viaduct on the river Marlantes with a dual carriageway and a height of 14 m forming part of the Reinosa section, on the border with the Palencia province.

The Flushing Line is an arch-based viaduct that was built in the early 1900s. The 128 pillars that make up the viaduct needed structural restoration. The pillars varied in height between 14 and 35 feet.

The original 4 lane bridge, constructed in 1961, was designed to be suitable for 75,000 vehicles per day for the next twenty years. The bridge reached this volume in 8 years, and today three times the forecasted quantity has been reached (200,000 vehicles per day). Improvement works have been performed on the bridge since the 80s.
Nonetheless, the construction of a new bridge is underway to solve the bridge’s bottleneck problems and improve circulation. The new Woodrow Wilson Bridge is one of the largest infrastructure projects in the USA.
ULMA Construcción has participated in the construction of the west accesses and piers.

This was the project for building a Bridge over the Bóbr River. It has three sections, and each section is 57 m long. The bridge segment of 14.55 m has two frames. These are 271 cm high, and their width varies between 70 and 94 cm. Support segment flanges are 3.25 m wide.
