Abandoned Highway Camp: What It Is & Why It Exists

An abandoned highway camp is a former temporary housing site built for workers who constructed roads, bridges, and highways, later left vacant when the project ended. These camps ranged from small bunkhouses to self-contained towns with mess halls, clinics, and recreation buildings. You typically find them along older highways, near mountain passes, or in remote areas where large-scale roadwork once required a resident workforce.

Formula

The calculator estimates the age of the camp (current year minus the year it was built) and the building density (number of remaining buildings divided by total area). Age is expressed in years; density is expressed as buildings per acre. The formula for age is:

Age = Current Year − Year Built

For density: Buildings per Acre = Number of Buildings ÷ Total Area (acres)

These simple calculations help you gauge how old a site is and how intact it remains, which is useful for historical research or planning a visit.

Worked Example

Using the default values: a 50-acre camp with 12 buildings still standing, built in 1935. The current year is 2025.

Age = 2025 − 1935 = 90 years

Density = 12 ÷ 50 = 0.24 buildings per acre

So the camp is about 90 years old, and you would find roughly one building for every 4 acres.

Why Were Highway Camps Built?

Before modern machinery and commuting, large road projects needed hundreds of laborers who lived far from towns. Camps provided housing, food, and basic medical care so workers could stay on site. During the 1920s–1940s, many highway camps were built by state highway departments or federal relief programs like the Works Progress Administration (WPA). They were often constructed from wood, with simple dormitories, a kitchen, and a foreman’s office. Some camps were semi-permanent, meant to last for years if the project was large (like a multi-span bridge or a mountain tunnel).

What Remains Today?

Most camps were dismantled after the road was finished. What remains varies:

• Foundations – concrete slabs or stone footings are the most common remnants.
• Chimneys and fireplaces – often survive because they are made of brick or stone.
• Wells and cisterns – water sources may still be visible as depressions or concrete rings.
• Dumps and trash pits – old bottles, cans, and tools can be found, but removing artifacts from public land is usually illegal.
• Overgrown roads – the camp’s internal paths may appear as faint trails.

Some camps were repurposed as ranger stations, youth hostels, or private cabins. Others became ghost towns, slowly reclaimed by forest.

How to Find an Abandoned Highway Camp

Locating these sites requires research and on-the-ground observation:

1. Check historical maps (e.g., old USGS topos or state highway maps) for symbols like “CCC camp� or “labor camp.�
2. Look for place names like “Camp 4� or “Work Camp� on modern maps.
3. Search local historical societies or state archives for project records.
4. Walk along old highway alignments that have been bypassed by newer roads.
5. Use aerial imagery (Google Earth) to spot rectangular clearings or foundation outlines.

Always get permission before entering private property, and never disturb structures or artifacts.

Common Problems and Misconceptions

One common mistake is confusing highway camps with prison labor camps or military camps. While some highway work was done by convicts (especially in the South), most camps were civilian. Another misconception is that all camps were from the Great Depression; in fact, many were built earlier or later. A practical problem is that “abandoned� does not mean “safe.� Old buildings may have rotten floors, exposed nails, or asbestos. Wildlife (snakes, rodents) often takes over. Also, poison ivy and other hazards are common. Always treat the site as unstable and avoid entering structures.

Safety and Legal Considerations

Exploring an abandoned camp carries real risks. Do not enter buildings – they can collapse without warning. Watch for rusty metal, broken glass, and deep holes (old wells). In many regions, these sites are protected as historic resources; removing artifacts or damaging structures can lead to fines. On federal land, the Archaeological Resources Protection Act prohibits digging or collecting. If you find human remains (rare but possible), stop and contact local law enforcement immediately. Also, be aware of hunting seasons and wear bright clothing if visiting during fall.

Alternatives to Visiting in Person

If you cannot visit safely, many archives offer virtual access. State digital libraries often have historic photos of highway camps. The Library of Congress has WPA and highway project photographs. You can also view old topographic maps online through the USGS Historical Topographic Map Explorer. Some museums have exhibits on road-building history. Documentary films about the construction of the Interstate Highway System sometimes show camp life. These resources let you explore without the physical risk.

Frequently Asked Questions

Are abandoned highway camps open to the public?
It depends on land ownership. If the site is on national forest or BLM land, you can generally walk around, but you cannot camp or dig. On state or private land, you need permission. Always check with the managing agency.

What is the difference between a highway camp and a CCC camp?
CCC camps were built by the Civilian Conservation Corps for young men doing conservation work (parks, erosion control). Highway camps were specifically for road construction crews. Some CCC camps later housed highway workers, so the distinction can blur.

Can I metal detect at an abandoned camp?
On federal land, metal detecting is usually prohibited without a permit. On state land, rules vary. On private land, you need the owner’s written permission. Even then, digging can disturb artifacts and is often frowned upon by historians.

Why are some camps still standing after 80 years?
Buildings made of stone or concrete survive longer. Also, camps in dry climates (like the Southwest) decay slower than those in wet forests. Some were maintained as storage or housing for later projects.

How do I find the exact location of a camp?
Start with historical maps, then cross-reference with modern GPS. Look for place names on current maps. Local hiking forums or historical societies often share locations, but be respectful of private property.

Is it safe to drink water from an old well at a camp?
No. The water is likely contaminated by rust, animal waste, or chemicals. Never drink from any well or spring at an abandoned site.
