ULMA takes part on the construction project of Eresma Arched Bridge in Segovia

Jan 31, 2019
The Eresma viaduct comprises one of the most heavily used transportation networks in the area, with the current volume of traffic tripling what was predicted in 2002, with 18,000 rather than 6,000 vehicles daily.

The uniqueness of this structure lies in its arched shape, with the deck placed on the upper part of the arch. For the arch, ULMA proposed a gantry falsework solution set on foundation to span the precipitously steep terrain. The geometry of the arch was formed with 20 m long H-33 Trusses to support the double sided formwork system used to form the curve.

The shoring system consisted in T-500 towers reaching 40 m in height, without the need for any additional bracing. The entire arch was built with only five supports.

All of the collective protective equipment necessary was supplied for the shoring towers, trusses, and formwork, making it possible to complete all auxiliary work in complete safety.

The effective coordination between the different teams in charge of planning, engineering and on-site assistance, together with ULMA's technical and logistical capacity, have been the decisive factors for the execution with guarantees of the viaduct over the Eresma River in Spain, which will improve the flow of traffic and road safety.
