L-shape Angles to fix the planks
KWIK Bolts SS to anchor the angles to the concrete were used

The North Tarrant Express and the Lyndon B. Johnson (LBJ) Expressway corridors have been one of the most congested in the United States. Drivers have been choosing the new managed lanes since the NTE and LBJ facilities opened in 2014 and 2015 respectively because it offers faster, safer and more reliable travel.

As part of their maintenance operations NTE Express and LBJ Express asked AZIERTA for the creation of winter routes to treat their entire concessions with brine and salt as a preventive measure.

The project consisted in the design and calculation of the retaining wall itself and the plates and anchors needed to fix it to both sides, one being an adjacent concrete retaining wall and the other being the sheet pile wall. The calculations checked member sizes, connections and anchorages for the required elements of the design.

For the design of the steel profiles needed, the software used was FLAC3D from ITASCA CONSULTING GROUP (Minneapolis, Minneapolis), which allows the modeling of complex problems.
