Interstate 430 (I-430) starts its 12.93 miles (20.81 km) route at a trumpet interchange with I-30, U.S. Route 67 (U.S. 67) and U.S. 70. From the interchange, I-430 travels northwest and runs over Highway 338 (AR 338) before having a diamond interchange with AR 5. The freeway goes north to pass Remington College and intersect Colonel Glenn Road before curving eastward to intersect Shackleford Road and then turning back north. Immediately after going under Kanis Road, the highway has a cloverleaf interchange with I-630, at its western terminus. After I-630, the roadway goes past Immanuel Baptist Church and Breckenridge Village to intersect Rodney Parham Road near the Colony West Shopping Center and later AR 10. The AR 10 interchange was the final I-430 interchange before the freeway crossed the Arkansas River on the I-430 Bridge. After the bridge, the roadway passes Rosenbaum Lake and intersects with AR 100 before ending at a three-way interchange with I-40 and U.S. 65.
1955 plan for I-430 and other Little Rock freeways
Early plans for the Interstate Highway System include a route along roughly the same alignment as the present Interstate 30 (I-30) through the Little Rock area, but are not detailed enough to show exactly how the cities would be served. Later, in 1955, a map of the Interstate Highway's plans shows a complete beltway around Little Rock, including present-day I-430, I-440 and Highway 440 (AR 440). When preliminary urban routes were laid out in 1955, the beltway was shortened to the current route of I-430.
