Key Bridge Rebuild Drives 8 of 12 Test Piles as Load Testing Nears

Officials say permanent work timelines hinge on upcoming load test results.

Overview

  • Maryland engineers are executing a 12‑pile program to verify foundation capacity before committing to full-scale construction.
  • Eight piles have been driven through soft riverbed sediment into the anticipated hard layer, confirming preliminary geotechnical assumptions.
  • A steel template will apply roughly 10 million pounds of force in formal load checks, with the test program expected to wrap up in early January.
  • Some test piles may be incorporated into the final foundation if they meet capacity criteria once testing is complete.
  • Demolition continues with the deck removed and about one‑fifth of the steel still standing, a process projected to run into early 2026 as officials remain cautious about schedule forecasts.
