Description	The project involves replacing the Interstate 5 bridge across the Columbia River, which is considered obsolete due to narrow lanes, lack of shoulders, and inability to meet traffic demand. The project is awaiting a decision from the U.S. Coast Guard on whether the new bridge will be a fixed span or a movable span, which significantly affects the cost estimate. The cost estimate is expected to be updated once the bridge design is finalized, with construction potentially starting in 2026 and completion around 2032 or 2033.
