About Vale Tunnel

Vale Tunnel is a retired railway tunnel located in Kansas City, Missouri. With more than a century’s worth of history, which will be discussed in further detail below, Vale Tunnel has been known by many different names. Two of the most well-known names besides Vale Tunnel include the CRI&P Tunnel and the Valley of Vale Tunnel. It is a single-track railroad that previously chartered people from Kansas City to St. Louis as a part of the Missouri Central Railroad system.

Vale Tunnel isn’t the longest tunnel in Missouri, just for fun! In fact, with its impressive size, this tunnel has well earned its title. From one entry to the next, Vale Tunnel measures around 441 feet. That’s the same length as six bowling lanes aligned from end to end!


Vale Tunnel was the fourth tunnel on the Chicago, Rock Island, and Pacific (CRI&P) Railroad line stretching between Kansas City and St. Louis. It was first constructed at the beginning of the 20th century, with the Chicago, Rock Island, and Pacific Railroad completing its construction between 1903 and 1904. Not only was it the fourth tunnel to be constructed on this railway, but it was also the final. It crosses beneath Bannister Road. 

The longest tunnel in Missouri operated successfully for many decades. Between 1904 and 1980, it was one of the main tunnels connecting Kansas City and St. Louis along the railway. However, despite having a successful operational career, the Vale Tunnel couldn’t run forever.

In 1980, the Vale Tunnel was officially closed for professional use along the railway. Despite many attempts to survive and thrive, its governing railroad line, then known as the Rock Island Line, filed for bankruptcy. With the railroad being liquidated in court, there were no train systems left to navigate through the Vale Tunnel.

However, the history of Vale Tunnel doesn’t end there. After its closure in 1980, there were several buyers, and consequently, owners, of the Vale Tunnel. Despite various changes, however, much of the rail line and Vale Tunnel have been untouched.

The most recent owner of Vale Tunnel came to own it in 2016. The buyer? None other than Jackson County, Missouri. That’s what leads us to the longest tunnel in Missouri today.

Vale Tunnel Today

After the local government of Jackson County, Missouri, purchased the abandoned and closed Vale Tunnel, the question arose of how to utilize this fascinating piece of history best. Keeping that in mind, they created the Rock Island Rail Trail.

The Rock Island Rail Trail is a local trail that includes Vale Tunnel. After Jackson County acquired the longest tunnel in Missouri, authorities developed a multi-phase plan to turn Vale Tunnel into a local experience. Both stages of the plan presented Vale Tunnel as the trail’s centerpiece. Workers completed the first phase of the Rock Island Rail Trail in June 2019, just three years after the county acquired the tunnel. Initially, the trail stretched 6.4 miles. Yet, the second stage, building on the blueprints and foundation from 2019, extended the Rock Island Rail. They finished this stage in 2021, adding another seven miles to the trail for a total of 13.4 miles, and installed lights in Vale Tunnel.

Eventually, they marked the completion of the second stage with a “Ride the Rock” event in the summer of 2021. Hundreds of cyclists attended, eager to be among the first to explore this unique trail. Now, many consider the Vale Tunnel and the Rock Island Rail Trail top locations to visit in Missouri. With miles of paved trails, this accessible wilderness experience allows you to immerse yourself in local culture and meet some of the local flora and fauna. When you’re on the trail, you can expect to see local animals such as deer, fox squirrels, and more!
