Marietta–Williamstown Interstate Bridge, Road bridge connecting Marietta, Ohio and Williamstown, West Virginia, United States
The Marietta-Williamstown Interstate Bridge crosses the Ohio River with four lanes carrying Interstate 77 traffic between the two states. The structure serves as a modern river crossing that handles thousands of vehicles daily and forms a key part of regional transportation infrastructure.
The current bridge replaced an earlier crossing in 1967 as part of a broader infrastructure development project in the region. The original 1903 structure pioneered an innovative design approach that influenced bridge engineering of its era.
The bridge links two neighboring communities and shapes the daily routines of people traveling between Ohio and West Virginia for work and visits. It has become woven into the fabric of how residents in both states move through their regions.
The bridge is part of Interstate 77 and connects directly to both cities, making navigation straightforward. Visitors should expect active traffic and plan for delays during peak travel times.
The current structure retains elements from the original 1903 design, blending modern engineering with historical legacy. This rare combination demonstrates how innovative engineering ideas can be carried forward across generations.
