Route description

I-430 starts its 12.93-mile (20.81 km) route at a trumpet interchange with I-30/US 67/US 70. From the interchange, US 70 joins I-430 as it travels northwest and passes over Highway 338 (Baseline Road) before having a diamond interchange with Highway 5 (Stagecoach Road). At the interchange, US 70 splits off onto Stagecoach Road to the east, with Highway 5 running west. I-430 goes north to pass Remington College and intersect Highway 300 (Colonel Glenn Road) before curving eastward to intersect Shackleford Road and then turning back north. Immediately after passing 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 Highway 10 (Cantrell Road). The Highway 10 interchange is the final I-430 interchange before the freeway crosses the Arkansas River on the I-430 Bridge. After the bridge, the roadway passes Rosenbaum Lake and intersects with Highway 100 (Crystal Hill Road) before ending at a three-way interchange with I-40/US 65.^[2]

History

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 I-30 through the Little Rock area but are not detailed enough to show exactly how the cities would be served.^[3] Later, in 1955, a map of the Interstate Highway's plans shows a complete beltway around Little Rock, including present-day I-430 and I-440.^[4] When preliminary urban routes were laid out in 1955, the beltway was shortened to the current route of I-430.^[5]

The American Association of State Highway and Transportation Officials (AASHTO) rerouted US 70 onto a portion of I-430 in May 2021 as part of a US 70 rerouting across Little Rock.^[6][7]
