Named after Jay B. Dillingham, a prominent figure in the history of the Kansas City Stockyards, the viaduct serves as a critical link within the regional transportation network, easing the flow of intercity and interstate traffic. Its strategic location—nestled between the Missouri Pacific Bridge to the north and the Central Avenue Bridge (Kansas City) to the south—underscores its importance in connecting key urban areas across the Kansas River.

The bridge features a multi-beam girder design, chosen for its strength and ability to support the significant volume of traffic characteristic of a major interstate route. Its construction in 1990 was part of a larger effort to improve connectivity and foster economic growth within the Kansas City area. The completion of the I-670 Viaduct represented a notable advancement in the region's infrastructure development.^[1]

As a vital component of the Interstate 670 corridor, the viaduct plays a key role in facilitating daily commutes and the transport of goods and services between Kansas and Missouri. The proximity of the bridge to important landmarks and economic centers, including the West Bottoms district, amplifies its significance in the local infrastructure network.
