Ohio and Kentucky officials just revealed the design for a new double-decker bridge that will be built next to the Brent Spence Bridge, a well-known choke point for freight and local traffic.

Why it matters: The Brent Spence Bridge has been called one of the nation's worst truck bottlenecks, with far more traffic than engineers first planned when it opened back in 1963.

• The new "companion" bridge will carry all I-71 and I-75 through-traffic, letting the old Brent Spence Bridge handle only local vehicles between Cincinnati and Covington.
• Both states are splitting the $3.6 billion cost evenly, and there will be no tolls.
• The fresh cable-stayed design means both the upper and lower decks are supported by cables, making the structure stronger and freeing up space for emergency shoulders.

Construction: Work is set to begin later this year. Officials expect the new bridge to open by 2032, after about eight years of building.

Once finished, the Brent Spence Bridge will be modified back to three lanes each way, improving safety and easing congestion. Keeping freight rolling quickly through this region is vital for the entire country, reported Wikipedia.
