Cable Bridge

The Cable Bridge is a cable-stayed structure spanning the Columbia River with concrete segments supported by cables extending from central towers, connecting Pasco and Kennewick. The structure carries State Route 397 traffic and features modern safety systems including rigid guardrails.

Opened in September 1978, the bridge became the first major cable-stayed structure built in the United States. It replaced the earlier Pasco-Kennewick Bridge that had served since 1922.

The bridge functions as part of the Sacagawea Heritage Trail, blending transportation with recreational pathways that locals use for walking and cycling along the river. The structure connects two communities that developed on opposite sides of the water.

Access is available for pedestrians and cyclists through Sacagawea Heritage Trail connections, with the best views of the structure from river shores. Keep in mind this is an active traffic route, so vehicle noise is present throughout the day.

The structure gained night illumination systems in 1998, making it a glowing landmark visible throughout the Tri-Cities area after dark. This lighting transformation turned it into a recognizable symbol for the region.
