[1] The reconstruction project was completed in phases from 2012 to 2015-[2][3]2016, at a cost of about $560 million,[4] with related construction beginning in 2009, replacing the old two-level clover-directional interchange.

The reconstruction was the final phase in a 12-step program to improve the highly trafficked Palmetto Expressway,[5] though in 2014 a new project to add express lanes to the Palmetto Expressway was proposed,[6] to begin construction in 2016.

Much of the new interchange opened in October 2015,[8] including the two highest flyovers,[9] with completion at that point scheduled for March 2016.

[11] The official announcement came in early October, very near budget ($563 million) but a couple years over time.

The project included moving a drainage canal and construction of 45 individual bridges, with the interchange serving 430,000 vehicles daily.
