The main object of the project is the construction of a footbridge in the Zaratamo prairie in the P.K. 7 + 607 within the work entitled “Suppression of level crossings and closure of the track between the P.K. 6 + 594 and 9 + 802 areas of the Bilbao-Donostia line”.
The walkway, which has already been hoisted by operators of Viuda de Sainz, will allow crossing over a line of FFCC Bilbao-Donostia and over the BI-3720 road, thus eliminating the dangers of the crossing.
The board of the footbridge is solved by means of a prefabricated trough beam with a concrete top slab in situ, total edge between 0.90 m and 1.00 m, and its accesses by stairs and elevators.
The prefabricated beam is completed with a concreting board in situ before placing pre-locks as lost formwork and that is attached at its ends to the supports to get the final solution to be embedded.
