Workers with Kiewit Infrastructure Group race to stabilize a fractured tie girder that forced an indefinite closure of the key Tennessee-Arkansas crossing.
Arkansas and Tennessee transportation officials say “a catastrophic event” was averted with the discovery of a fractured steel beam in the I-40 Mississippi River Bridge, but it could be months before the crossing is fully repaired and reopened to traffic.
The emergency stabilization of the 36-year-old West Seattle Bridge reached a new milestone after external post-tensioning and the release of a damaged Pier 18 bearing was completed Nov. 10, allowing crews to move toward wrapping girders in carbon fiber.
