A Reduction in Excavation and Backfill for a Tennessee Road Widening Project sticky icon

Reinforced Earth MSE Wall

The bottom line is safety, and that was especially true for approximately 12 miles of SR 16/US 41A between Shelbyville and Tullahoma, about 80 miles southeast of Nashville. This corridor was studied in the mid-1990s by Tennessee Department of Transportation (TDOT) for possible operating deficiencies. TDOT determined that the projected 60% traffic growth by the mid-2010s would lead to more accidents and lower overall safety on what was, essentially, a 2-lane country highway.

Florida's Turnpike - Designing Veterans Expressway Improvements sticky icon

Reinforced Earth Product in Field

Introduction

Construction on the $380 million Veterans Expressway widening project started in summer 2013. When the project is completed, two lanes will be added in each direction: one an express lane, the other a general use toll lane. The project includes 65 Reinforced Earth® MSE walls, totaling 648,420 square feet of wall facing (11 football fields).

Challenges

Faster Travel Time Around Atlanta sticky icon

To provide access to and from both travel directions of the adjacent mainline roadways, managed lanes are often constructed in the highway median. In this sometimes narrow space, Mechanically Stabilized Earth (MSE) retaining walls can efficiently retain grade differences across the median between the flanking mainline roadways, supporting ramps, and bridge abutments that are typical of reversible lanes.

Jimmy DeLoach Parkway Eases Flow of Panama Canal Freight: Relieves Truck Congestion sticky icon

Did you know that the Panama Canal flows all the way to Savannah, Georgia?  Maybe not literally, but the Port of Savannah has the largest single container terminal in North America and, in its fiscal year ending June 30, 2015, handled 3.66 million Twenty-foot Equivalent [container] Units, or TEUs. The TEU is the standard measure of containerized freight, equivalent to 20 ft. x 8 ft. x 8 ft., and containers based on this standard can be moved seamlessly between ships and trucks.

Hartsfield-Jackson Atlanta Airport sticky icon

When the City of Atlanta leased 287 acres of land for an airfield in 1925, no one imagined that in 2013 nearly 95 million passengers would pass through what became the world's busiest airport, Hartsfield-Jackson International.  Similarly, the inbound roadway system designers of the late 1970s could not have envisioned the doubling of automobile traffic that would clog airport entrance roadways some 30+ years later.  So to improve traffic flow and provide for the airport's continued growth, the Inbound Roadways Project was begun in 2013.
