The IH 35E near Dallas: DYWIDAG Strand Tendons contribute to the Widening of an important Transport Link

The Interstate 35E is the eastern part of IH 35 and leads through Dallas and Denton counties in Texas. During the widening of the 45km long eastern section, one new general purpose lane per direction as well as two reversible managed lanes are being built.

The main challenge in this project was to accommodate the designed tendon sizes in the anchor caps, which was achieved in close cooperation between DSI and the designers.

Since this is a design/build project, DSI was able to propose a change to some of the original post-tensioning design, modifying the quantity and size of the tendons to reduce the use of different equipment sizes and to optimize installation.

DSI USA supplied DYWIDAG Strand Tendons for a section of this project to post-tension theroad overpass structure. In total, 121 Type 37-0.6" DYWIDAG Strand Tendons, 40 Type 27-0.6" DYWIDAG Strand Tendons and 8 Type 19-0.6" DYWIDAG Strand Tendons were installed in the structure.
