Retaining Walls
Charlottesville, Va., is an historic city that was home to several of our founding fathers, and today hosts the Virginia Film Festival and houses the University of Virginia.
It also is home to a portion of U.S. Rte. 29 which cuts through the city as it makes its way from Pensacola, Fla., to...
Redi-Rock Limestone texture retaining walls
The Lumpkin Road Reconstruction Project should have been relatively routine, but the deeper Houston’s Memorial City Redevelopment Authority dug, the more problems they encountered.
With design parameters stacking up on each other, meeting the tight budget and even tighter schedule proved...
During the fall of 2016, a particularly bad storm hit a shoreline road in Gisborne, New Zealand. Monstrous waves slammed into the shoreline slope, which eroded away due to oversaturation and lack of foundational support. The erosion washed away part of the slope and took a portion of the road with...
When a road turns into a raging river, it becomes both dangerous and damaging. This is exactly what happened in July 2013, when the city of Lebanon, N.H., was swamped with more than 4 in. of rain within 48 hours—2 in. fell in just 45 minutes. The deluge caused flash flooding, which left residents...
All great visions have to start somewhere. This one began with over 3 miles of paved multi-purpose trail winding through the scenic Clear Creek Canyon near Denver.
Installing the retaining walls was no easy task, as the terrain includes steep slopes, flooding issues along the river, active...
The retaining wall creates a safe place for truck drivers to chain-up their tiers during snowy weather
The Challenge:
When it snows in Vail, Colorado, it’s a skier’s dream—but for drivers, especially of trucks maneuvering steep mountain roads, it can be treacherous. To make things safer, the Colorado Department of Transportation (CDOT) wanted to widen I-70 at both sides of mountain pass locations...

The Nevada Department of Transportation (NDOT) has substantially completed a project to enhance traveler safety and roadside water quality on U.S. 50 in the Cave Rock area of Lake Tahoe nearly one month ahead of schedule.
All U.S. 50 travel lanes through Cave Rock are now open. Since the project'...
For several years, the busy intersection of Lafranier Road and South Airport Road in Traverse City, Mich., near the Cherry Capital Airport was also one of the most dangerous. The steep, 12% grade at the end of Lafranier Road made it difficult for drivers to stop as they approached the South Airport...
The intersection of Rybolt and Wesselman Roads in Green Township, Ohio, was notorious for its significant visibility problems and heavy traffic. With construction starting in 2014 on a new subdivision nearby, Hamilton County officials initiated plans to widen the intersection to allow for the...
The Paseo Del Norte/I-25 Interchange is one of the busiest corridors in New Mexico, often producing major traffic congestion issues during rush hours. The city of Albuquerque needed a way to make it easier and safer to travel on the highways, and wanted to incorporate a pedestrian walkway and bike...
All lanes of traffic remained open during construction of the Redi-Rock retaining walls, which are designed to install quickly and within a small footprint.
THE CHALLENGE
In 2015, the Kentucky Transportation Cabinet (KYTC) began work on the multi-million-dollar New Circle Road widening project in Lexington. The scope of the project included nearly 3.2 miles of lane additions, shoulder widening, on-ramp and exit ramp realignment, and bridge widening...
THE CHALLENGE
In September 2013, floods ripped through Boulder County, Colo., massively damaging the roads—leaving many of them in very dangerous conditions for travelers heading into the mountains.
The stream bank parallel to Lee Hill Road had seriously eroded and was threatening the stability...

Mechanically stabilized earth walls, or MSE walls, are commonly used to stabilize backfill around bridges or for retaining walls along freeways. In the last 15 years, UDOT’s use of MSE walls has become routine where retaining walls are required.
UDOT has a database of over 700 MSE walls in use...
Case Studies
The “before” photos of this project are not a pretty sight. A river running below this Washington road had undermined the base of the slope, while runoff had heavily eroded an extremely steep hillside above the road.
“Between the hydraulics created by the hill on the back side and the river...
A host of difficult elements combined to require extreme engineering to solve a gravity wall problem on Q Street between 168th and 180th in Omaha, Neb.
This case entailed adding a lane to and widening a stretch of road over a creek, while retaining the existing road’s elevation. It wasn’t a very...
