Along with construction of the Cache Tunnel, an agreement was entered into with Pine Glades Development to install the infrastructure for an attached housing development. With views of the National Elk Refuge and Grand Tetons, the development – built on the side of a mountain – pushes the construction limits. With most of the roads supported by retaining walls, mechanical walkways under the driving surfaces extending for nearly 1,000 feet, townhouses built directly over the driving lanes, elaborate lift stations, and connection to the Cache Tunnel, the construction of the Pine Glades Development is widely viewed as one of the most ingenious concepts in Jackson Hole, Wyoming.
