New Tamoios Highway: DSI Prepron supplies DYWIDAG Strand Tendons for several Bridge Structures

Currently, the New Tamoios Highway bypass is being built around Caraguatatuba and São Sebastião, two coastal towns on the northern coast of the federal state of São Paulo, Brazil. The 33.9km long road includes 5 tunnels, 44 bridges and viaducts.

DSI Prepron has already contributed to the expansion of the Tamoios Highway,the main access to the north coast, and is now supplying high quality products and services for several bridges and viaducts for the extension of this highway.

Type 6-0.5", 10-0.5" and 12-0.5" DYWIDAG Strand Tendons were used for post-tensioning the different bridge girders. Furthermore, DSI Prepron supplied specialists on site during the installation of the post-tensioning tendons.
