Little Rock to Clarksville: Ultimate Road Trip Guide

This 350-mile route follows Interstate 40 for most of its length, crossing the Arkansas River Valley, the Ozark foothills, and the Tennessee Plateau. A little-known fact: the highway shadows the old Trail of Tears route, making this drive a journey through both natural beauty and poignant history.

The drive takes approximately 5.5 hours without stops, but you'll want to allow 7–8 hours to explore. Major highways include I-40 (exit 161 in Little Rock to exit 1 in Clarksville) and brief sections of I-24 and US-79. For tips on how to find the best stops and hidden gems between cities, check our essential guide.

I-40 is a well-maintained four-lane highway with a speed limit of 70 mph in Arkansas and 65–70 mph in Tennessee. Rest areas are plentiful every 30–40 miles. Key exits: Exits 271 (West Memphis AR) for casinos, Exit 279A (Memphis TN) for downtown, Exit 82 (Jackson TN) for dining, Exit 143 (Nashville) for detour, and Exit 1 (Clarksville TN) for Fort Campbell.

• Fuel costs: Around $35–$45 for a typical sedan (gas at $3.00/gal). Cheapest fuel found in West Memphis, AR and Jackson, TN.
• Tolls: Only if you take I-440 around Little Rock ($0.50). Otherwise free.
• Electric vehicle charging: Tesla Superchargers in Little Rock, Memphis, Jackson, and Clarksville. Level 2 chargers at many hotels.

Weather considerations: Arkansas and Tennessee have humid subtropical climates. Summer temperatures reach 90°F with high humidity; winter can dip to 30°F with occasional ice. Spring and fall offer mild temps (60–70°F) and vibrant foliage. Best driving months: March–June and September–November for clear skies and colorful landscapes.

The route transitions from the flat Mississippi Delta to the rolling hills of Middle Tennessee. Notable natural attractions include the Big River Crossing (Memphis) – a 1-mile pedestrian bridge over the Mississippi – and the Tennessee National Wildlife Refuge near Paris, TN, home to bald eagles and migratory waterfowl. For a detour, visit Pinson Mounds State Park (south of Jackson, TN), which contains prehistoric Native American mounds dated to 1000 BCE.

• UNESCO designation: None directly on route, but the nearby Cahokia Mounds (IL) are a World Heritage Site, a 3-hour drive from Clarksville.
• Local commerce: Don't miss the Memphis Farmers Market (downtown, Saturdays) for handmade arts and fresh produce; in Jackson, the Nativly Made Market offers artisan crafts.

Climatic conditions along the route: Expect significant humidity in summer, making air conditioning essential. Fall (October–November) provides stunning leaf colors, especially in the Ozark foothills near Russellville, AR (detour via AR-7). Spring (April–May) brings blooming dogwoods and redbuds. Note: Flat sections in Arkansas can experience crosswinds; be cautious when driving large vehicles.

Hidden off-route spots: At exit 56 in Arkansas, take AR-149 south to visit the town of Brinkley (birthplace of the rice industry). For a ghost town, explore the Old Davidsonville State Park near Pocahontas, AR – an early 1800s settlement abandoned after a tornado. In Tennessee, turn off I-40 at exit 126 to see the Natchez Trace State Park, offering hiking trails and a restored 19th-century inn.

I-40 is generally safe, with a few construction zones near Memphis. Avoid driving through downtown Memphis during rush hours (7–9 AM, 4–6 PM) due to traffic. The Tennessee Department of Transportation has a real-time traffic app. In 2022, I-40 had a fatality rate of 0.8 per 100 million miles, lower than the national average.

• Family-friendly stops: The Memphis Zoo (exit 1, I-240) is a top attraction. The Children's Museum of Memphis is interactive and educational. In Jackson, visit the Casey Jones Home & Railroad Museum.
• Pet-friendly framework: Most rest areas have pet areas. Pet-friendly hotels include La Quinta (every major town). Recommended vet: Memphis Animal Hospital (emergency 24/7).

Fatigue management: Take a break every 2 hours. Recommended rest zones include the I-40 Rest Area near mile marker 60 (Arkansas) with picnic tables, and the West Tennessee Rest Area near mile marker 79 (just past Jackson). For caffeine, the Starbucks in Jackson (exit 82) is open late. Consider using the hidden gems guide to plan micro-breaks.

Culinary infrastructure: Little Rock's River Market District offers Southern cuisine (try the fried catfish at The Root Café). Memphis is famous for barbecue – Rendezvous (dry rub ribs) and Central BBQ (smoked wings). In Jackson, the Old Country Store serves fried chicken and biscuits. For a quick bite, exits 82 (Jackson) and 163 (Dickson) have fast-food chains.
