The piles for the north and south pylons are hollow steel pipes – over 200 feet long and 8 feet in diameter driven deep into the riverbed to support the bridge foundation and pier protection fender.
Completion of permanent piles installation for the South Pylon (Pier 24) anticipated Spring 2027.

A temporary structure made of 36″ steel pipe piles, steel girders, and a timber mat surface that provides direct access from land to the bridge piers for construction crews, materials and cranes. Once construction is complete, the work platforms will be removed and reused/recycled.
Completion of South Main Line Trestle (Work Platform) anticipated Fall 2026.

The Federal Highway Administration (FHWA) approved the Categorical Exclusion (CE) for the Key Bridge Rebuild Project in July 2024. The CE confirms that the project will restore a critical interstate transportation link while avoiding significant impacts to nearby communities and natural or cultural resources. The project is expected to have substantial transportation and socioeconomic benefits and WILL NOT:
Pre-construction activities were completed in July 2025. Activities included wind tunnel testing, survey & mapping, scour testing, property inspections, bridge alignment and geotechnical investigations.
Demolition of the existing bridges over land was completed in February 2026. On land, the team removed 20,000 tons of concrete decking and concrete columns, along with 160 steel girders on both the north and south sides of the bridge.
The Test Pile Program was successfully completed in February 2026, confirming the strength and performance of the project’s foundation design and allowing the team to move directly into driving permanent piles. The test piles were 8 feet in diameter and over 200 feet long.
