Price of Brent Spence Bridge Project Rises Nearly $800M

Inflation in construction costs blamed for 22% increase in project budget to $4.39 billion.

The price tag for the long-planned Brent Spence Bridge Corridor project in Ohio and Kentucky has risen from $3.6 billion to $4.39 billion, a 22% increase. Transportation officials cite inflation in construction materials as the primary driver behind the nearly $800 million cost hike.

Why it matters

The Brent Spence Bridge is a critical transportation link between Ohio and Kentucky, carrying Interstates 71 and 75 over the Ohio River. The project aims to reduce congestion and improve safety by adding a companion bridge and making other highway improvements. The significant cost increase could impact the project timeline and financing.

The details

The Ohio Controlling Board has approved the higher $4.39 billion price tag, allowing Ohio and Kentucky to finalize construction plans and begin work this spring. The earlier $3.6 billion estimate was made four years ago, before much design work was completed. Transportation officials say construction material costs have risen 60% or more compared to that time.

  • The Brent Spence Bridge Corridor project is scheduled to break ground this spring.
  • If construction schedules hold, the new companion bridge is expected to open in 2031.
  • Work on the existing Brent Spence Bridge will follow the completion of the new bridge.

What’s next

Initial work this spring and summer includes utility relocations, building demolitions, and tree clearing for the new bridge. Project crews will also begin work on approaches to the companion bridge, including bringing in barges and cranes to the Ohio River for construction of foundations and bridge pylons.

The takeaway

The significant cost increase for the Brent Spence Bridge Corridor project highlights the ongoing challenges of infrastructure investment, with inflation and rising material prices straining project budgets. However, transportation officials remain committed to moving forward with this critical transportation link between Ohio and Kentucky, despite the higher price tag.
