TX State Highway 45 Southwest State Highway 45 Southwest is a four-lane toll road located around sensitive environmental areas, including the 1,250-square-mile Edwards Aquifer Recharge Zone. The Edwards Aquifer is the key supplier of water in San Antonio and parts of Austin. In addition to building in an eco-friendly setting, State Highway 45 is adjacent to a residential neighborhood. In order to minimize disruption to the neighborhood and keep residents safe, Helix construction used social media to coordinate with the local Home-Owners Association and notify residents of major changes. Part of Highway 45 was built out of sequence to accommodate safe passage for school buses. The Helix construction team coordinated with the local school district and residents in order to plan around school bus routes.

DFW International Airport Terminal D Elevated Roadway and Skylink Automated People Mover
Helix construction served as a major subcontractor on the construction of the new Terminal D at DFW Airport. Helix construction performed on two major construction packages. The first was a two-level elevated roadway system to provide access for arriving and departing passengers at Terminal D, and two-level addition to Parking Garage at Terminal D. The elevated road sections were designed using a post-tension system of both multi-strand and mono-strand cables. Helix also constructed two four-story concrete tram stations and 2,500 lineal feet of elevated concrete super structure for the Skylink Automated People Mover System at Terminals D, E, and F. The elevated rail sections were 60 feet above grade and all concrete was cast in place. Helix self-performed cast-in-place columns, elevated bridge structures, and all concrete work.
Delta Air Lines Enabling Project
The Delta Air Lines Enabling project included preconstruction services and relocation of Delta Air Lines, and 28 other airlines, at Los Angeles International Airport. Referred to as the “LAX Terminal Shuffle” and “Airmageddon,” the relocation was the largest of its kind in U.S. aviation history.
The project included migrating Delta Air Lines’ operations from LAX Terminals 5 and 6 to Terminals 2 and 3. The relocation was part of a long-term plan to connect Terminals 2 and 3 with the Tom Bradley International Terminal, which will increase Delta’s flight capacity and international operations at LAX.
Scheduling, testing and budgeting preconstruction services helped determine the most efficient way to move 28 airlines while keeping travelers safe and flight operations on schedule. Months of logistical planning, scheduling and construction culminated in a carefully orchestrated series of tear downs, builds and moves over the course of three nights without disrupting normally scheduled flights.
In order to manage the logistical complexity of the historic relocation, the team brought all stakeholders together to collaboratively plan for success. During the final nights of the shuffle, the team coordinated changes with airport staff, every airline and their individual stakeholders, including employees and passengers, trade partners and owners.
Helix construction committed to a 24/7 schedule in order to ensure successful delivery in a scenario where extra time was not an option. Work was completed on-time, throughout five terminals equaling 28-square-miles, in 125 unique work areas including baggage handling systems, airline clubs, gate counters, ticketing offices, IT rooms, ramp operations areas and flight display monitors.
