Track Capacity Expansion using Strand Tendons: The I-10 Neches River Bridge
The main East-West railway corridor in Beaumont, Texas, crosses the I-10 Neches River Bridge, a vertical lift span bridge that allows ships to pass under the structure. The single track bridge is usually open for ship traffic between 15 and 30 minutes, and 40 to 50 trains cross the bridge each day.
In order to add track capacity to the railway connection over the Neches River, a new structure is being built parallel to the existing bridge. In this project, DSI USA was the contact point between the General Contractor Williams Brothers and Mexpresa, the company supplying the form travelers.
A total of 634 Type 4-0.6" DYWIDAG Strand Tendons were used as transverse tendons in the bridge segments.
Longitudinal post-tensioning was carried out using 372 Type 12-0.6" DYWIDAG Strand Tendons and 4 Type 7-0.6" DYWIDAG Strand Tendons. DSI also supplied the equipment needed for stressing and grouting and supported the jobsite during stressing.
