Brent Spence Bridge Project at Crucial Point

Ohio Department of Transportation Director Jerry Wray announced on Friday that the Brent Spence Bridge project is at a crucial point.  Currently, the state of Ohio has legislation allowing for the bridge to be built by a public-private partnership. A similar bill is being considered in Kentucky at the moment, but the project cannot move forward if it is not passed. The new Brent Spence Bridge will cost an estimated $2.6 billion to remove the existing bridge and construct the new version.

Pennsylvania Department of Transportation plans to replace 500 bridges in the state starting in 2015, and the majority of these bridges will be built under public-private partnership contracts.  Currently 4,200 bridges, or 18% of the state’s bridges, are structurally deficient. This figure is 11% higher than the national average.  This should not be too surprising, however, because the average age of a bridge in Pennsylvania is around 50 years old.  Also, the majority of the bridges listed as structurally deficient require only minor repairs, or they are deteriorating and might need weight restrictions in the future as a result.  All of the bridges are safe, but PennDOT has identified 300 bridges that they would like to use public-private partnerships to replace.  Under a public-private partnership, a private company or team must design, build, and maintain each bridge.  PennDOT will pay the team based on their performance.
