Mapping the Jefferson Highway

If you would like to drive any or all of the historic Jefferson Highway, you've come to the right place. Our official highway map is located on this page. If you have never driven the route of an old historic highway before, there are several things you need to be aware of before opening the map, loading up the car, and heading out on the road. As you plan your trip along the Jefferson Highway it will be important to keep several things in mind:

• The Jefferson Highway Association came into existence in 1915 and the initial routing was conceived between Winnipeg and New Orleans by 1916. The "route" meant that key cities and states were defined by 1916, but the actual roadways connecting those cities were not fully established. The actual driving route was developed over time, and it changed over the next decade. This is a reason that it is difficult in certain areas to define a single modern route that was the Jefferson Highway in some areas but there can be close approximations.  This is no different than many historic highways across the United States. 
• A second problem is that there wasn't a single route in certain areas. Rather than making a difficult decision choosing one potential route over another, the JHA (and many other highway associations of the time) arbitrarily created multiple routes rather than choosing one best alternative. So, for example, the Jefferson Highway takes different routes from Joplin, Missouri to Kansas City, Missouri - two through the state of Kansas and one through Missouri. There are several cases like this, including adding a route through the state of Arkansas as a late add-on.
• The term "highway" meant something very different a hundred years ago than it does today. A highway was an improved road, meaning anything from dirt to macadam to (in very rare cases) paving. Most of the time it was only "improved" during dry weather. Rain was not your friend. Importantly, significant sections of the original Jefferson Highway remain unpaved today. You may want to consider alternative routing in those cases, especially if you are driving a classic car with a $15,000 paint job.
• The original Jefferson Highway doesn't exist in all areas, having been replaced or bypassed by Interstate highways. On the other hand, the original JH became the basis for parts of the U.S. Highway System established in 1926. Anyone creating a drivable map of the Jefferson Highway today is faced with hundreds of arbitrary decisions about how to connect these orphaned sections of the road together.
• The bottom line is that the official Jefferson Highway map shown below is at best a rough approximation of what and where the original roadway ran at this time.  it is constantly being reviewed and updated from time to time.  At some point, there will be a defined official guide and map , but at present this is our best attempt.
