Diverging Diamond Interchange The new interchange bridge is being constructed just north of the existing bridge, leaving most roadways west of the interchange relatively untouched. The Diverging Diamond interchange design has a narrow footprint, which helps avoid touching most businesses during and after the project.
enter I-5 or to cross it. This movement reduces the number of signal phases a driver needs to clear.” 3-D traffic simulation video “How will I negotiate the new interchange design?”
The design also helps keep traffic congestion to a minimum while increasing safety.
That’s a frequent question ODOT hears from local drivers and Phoenix residents, including stakeholders who followed the project’s long development process.
“The Diverging Diamond design provides a higher capacity to move traffic while reducing right of way needs,” said Steers. “Drivers will move to the opposite side of the road to
A 3-D traffic simulation completed in 2013 shows how the new crossing diamond interchange will operate. The simulation is featured on the project website.
