Six Injured in Brent Spence Bridge Crash

Six people were injured this weekend in Cincinnati, Ohio when a car fell off the southbound deck of I-75 and landed on the northbound lanes of the highway below.  According to witnesses, a car tried to take an exit off I-75 that was located in the right lane by quickly cutting over from the left lane. A semi-truck ended up colliding with an SUV and sent the car over the guardrail. Six people were sent to the hospital with non-life threatening injuries. The eight-car pile-up closed all lanes of the bridge for two hours on Saturday.

The Kentucky Department of Transportation has been trying to build a new bridge on I-69 over the Ohio River for many years. The bridge would link Henderson, Kentucky and Evansville, Indiana. When the bridge was first being discussed a decade ago, a $1.4 billion price tag was the popular estimate for the bridge’s cost. This cost estimate proved prohibitive for any discussion of building the bridge as taxpayers felt it was going to be far too expensive to complete the project.  Now, however, a Henderson-Evansville I-69 advocacy group is presenting a modified vision of the project that would lower the cost to $800 million.

Video: Milton-Madison Bridge Truss Slide

The Milton-Madison Bridge spanning the Ohio River and connecting Milton, Kentucky and Madison, Indiana made history last Thursday, as it became the longest bridge in North America to be slid laterally into place. Workers spent many hours on Thursday sliding the half-mile-long bridge into place from temporary piers adjacent to the permanent piers. The 30 million pound span was pushed 55 feet using steel cables and eight computerized hydraulic jacks.

The Kentucky and Ohio Departments of Transportation announced that toll revenue would be required to fund the design and construction of a new Brent Spence Bridge. Current estimates place the cost of a new bridge at $3.57 billion.  The current Brent Spence Bridge is a double-decker cantilever truss bride that crosses the Ohio River.  It allows residents of Northern Kentucky to commute to Cincinnati, Ohio and vice versa.  The bridge was opened in 1963 and was designed to carry 85,000 vehicles per day.  As of 2007, 155,000 cars cross the bridge each day, and about 65% of the cars travel from Kentucky to Ohio.  In 2011, large pieces of concrete fell from the upper deck of the bridge onto the lower level, and the bridge was closed down for a day to repair the damage.  While it currently is considered to be structurally safe, many residents of Ohio and Kentucky have lost faith in the functionality of the original bridge.  As a result, the two states departments of transportation are currently studying the bridge to determine if it will be better to replace or rehabilitate the Brent Spence Bridge.
