Salt Storage Design

NTE Express & LBJ Express Concessions

SUMMARY

Recommendations mode in accordance with the Texas Manual on Uniform Traffic Control Devices (TMUTCD); Taxes State Inspection Manual and Methods.

Ramp closure is expected to begin in the evening during non-peak hours.

The new LBJ Express has increased the driving capacity of the old LBJ. Up to six new managed lanes have been added in the I-635 section, and four on the I-35 section. This extension aims to cover the needs arising through population growth over the next 30 years.

Overall, works have comprised the building of a concrete structure the size of 120 football fields and a wearing surface equivalent to 280 fields, with the excavation of close to 7 million cubic meters of earth. Roughly, 100 km of pilings have been used, while 330 km of prefabricated beams and 320,000 m2 of different types of walls have been put up. The 9 lanes in each direction required the construction of over 350 km of lanes, with one section of the highway having up to 28 lanes.

LBJIG asked AZIERTA to assist in the preparation, and submittal of the design for the salt storage building with deceleration lane to allow salt loading trucks and maintenance vehicles to safely access the building.

The project includes drainage, grading, structural foundation, BMP, trees planting, and deceleration lane for two 33-ton salt storage buildings. The Project is under construction and will be completed by February 2023.
