The Astoria-Megler and St. Johns bridges were among the dozens of spans across the country recommended to undergo "vulnerability assessments" by the National Transportation Safety Board.
The article from OPB discusses the safety concerns and preventive measures for bridges in the Pacific Northwest following the collapse of the Francis Scott Key Bridge in Baltimore due to a ship collision. It highlights the Astoria-Megler Bridge and the St. Johns Bridge as critical structures that could face similar risks. The Astoria-Megler Bridge, spanning the Columbia River, has implemented protective dolphins to absorb potential impacts from ships, while the St. Johns Bridge in Portland, although not directly protected by dolphins, benefits from its location in a less busy shipping channel. The article also mentions ongoing efforts by the Oregon Department of Transportation to assess and enhance bridge safety, including regular inspections and the consideration of additional protective measures to mitigate the risk of collisions with large vessels.
