After close to two years of construction, the new diverging diamond interchange is scheduled to open Monday morning at Glades Road and Interstate 95 in Boca Raton.

To facilitate the implementation of the new design, the Florida Department of Transportation said all access to and from Glades Road at I-95 will be restricted this weekend.

The interchange will reopen in the new configuration at 6 a.m. Monday.

A diverging diamond interchange allows the two directions of traffic on the roadway to temporarily cross to the opposite side of the road, according to FDOT.

This limits the number of traffic signal phases and allows drivers to make a left turn without crossing in front of oncoming traffic. The lanes then change back to the right side of the road.

FDOT said the benefits of this type of interchange include improved traffic operations, increased safety and enhanced accessibility for all drivers.

Construction on the project began on Glades Road in March 2021 with roadway widening, drainage, bridge widenings and retrofit over I-95 and Military Trail, and the construction of new ramps and a dedicated median pedestrian bridge.

FDOT said additional project improvements include the following:

  • Installation of new drainage structures, lighting and utilities
  • Wrong-way driving countermeasures
  • 18 new signal mast arms
  • Five new overhead sign structures
  • Construction of pedestrian pathways
  • Two 7-foot bike lanes on either side of the road

Law enforcement will be at the site this weekend and from 11 p.m. to 10 a.m. and 3 p.m. to 7 p.m. daily for the first two weeks after implementation to ensure that drivers are following the new traffic pattern.

The diverging diamond configuration is a relatively new traffic flow design for American drivers, first implemented on a roadway in Springfield, Missouri, in 2009.

Since then, there are more than 150 of these types of interchanges now open to traffic throughout the U.S, with more under construction.

The innovative design has been praised for reducing injury and fatal crashes by up to 55%, according to 2021 study.

FDOT said they project a 33% crash reduction at the interchange once the diverging diamond configuration takes effect.

The new interchange is part of an I-95 express phase project that FDOT started in November 2019 with a price tag of $148 million.
