Development calls for tenders to extend the drainage capacity of the Rambla de Viznaga at the intersection of two roads of Lorca (28/06/2016)

The Ministry of Public Works and Infrastructure, through the Directorate General of Highways, has tendered the expansion project of the drainage works of the Rambla de Viznaga at the junction with the RM-11 and RM-621 roads in Lorca.

The tender budget amounts to 2,000,286 euros and the deadline for bids ends on July 14.

Rambla de Viznaga born from the union of the wadis Nogalte and Vilerda and collects the flowing waters of the wadis of the Torrecilla, Bejar and part of the Nogalte.

It is characterized by low rainfall and low runoff coefficient, a situation that makes it can reach a very important flow, as happened in the flood of St. Wenceslas.

This action, which was published on June 18 in the Official Gazette of the Region (BORM), will run on the RM-11 road, which links the towns of Lorca and Aguilas, and RM-621, which links the city of the Sun with the deputation of Puri, in order to increase the drainage capacity of the promenade and avoid the possible effects that could be caused in the event of flooding.

The aforementioned roads now have a drainage system consisting of 21 frames and this performance, whose execution time is six months, includes the construction of 22 new frames between the two road infrastructure, which will double its capacity to drain.

On the road connecting the towns of Lorca and Aguilas it includes the construction of 14 frames, with dimensions of 4.50 meters wide by 2.7 meters light up.

Thus, the route will have a total of 30 arches and can evacuate 1,250 cubic meters per second.

RM-621 in the construction of eight new arches of 4.50 meters wide light by three meters high is contemplated, which will have a total of 13 frames.

Its discharge capacity is increased by 400 cubic meters per second.
