IDEAM, S.A. is carrying out, together with LRA, the technical assistance of the disassembly and construction of the new viaduct of the connection of the M-607 with the M-40 in Madrid, for the Road Administration (“Demarcación de Carreteras de Madrid”). The contractor is “Grupo Puentes”.
The work of dismantling the typical spans of the Viaduct began last December through the use of intermediate props and cut the section of the deck with diamond wire and its subsequent removal by means of a large capacity crane.
In the main span on the M-40, auxiliary upper steel truss beams are being used, from which the main span is hung for subsequent cutting and descent of the segments.
Recently the first precast beam of the new deck has already been placed.
