I-95 Express Lanes Phase 3B-2

Project Detail

I-95 Express Lanes Phase 3B-2 will extend the existing Express Lanes north from just south of Glades Road to just south of Linton Boulevard in Palm Beach County. One lane will be added and the High Occupancy Vehicle (HOV) lane will be converted to create two Express Lanes in each direction.

Project Highlights

The scope of work also includes the reconfiguration of the SR-808/Glades Road Interchange to a Diverging Diamond Interchange (DDI). Other project improvements are milling, resurfacing, and overbuilding the existing I-95 travel lanes and shoulders, widening the roadway, guardrail, barrier wall, attenuators, shoulder gutters, drainage, retaining walls, overhead sign structure installation, portable traffic monitoring sites, gantries, and associated infrastructure (including the construction of equipment buildings), installation of Intelligent Transportation System (ITS) and Express Lane Markers, signing and pavement markings, new signalization, lighting, utility relocation and ramp signaling at five interchanges from Glades Road to Linton Boulevard.

Shoulder-mounted sound barrier walls will be constructed along I-95 northbound between Clint Moore Road and Linton Boulevard, ground-mounted sound walls were installed on Yamato Road adjacent to the University Heights Community and along I-95 northbound south of Linton Boulevard adjacent to the Tierra Verde Community.

  • Eliminates overpass with an additional through lane in the westbound direction.
  • Goes from three to five through lines for I-95 access.
  • Enhanced safety for bicycles and pedestrians with a 7-foot buffered bicycle lane.
  • New 10-foot shared-use path for pedestrians and recreational cyclists through the interchange.
  • Eliminates ramp flyover bridge over Airport Road.
  • Eliminates traffic weaving from the city’s utility complex.

Client: Florida Department of Transportation

Location: Boca Raton, Florida

Area: 5.8-mile section

Start Date: 2019

Value: $148 Million

Remarks: The reconfiguration of the SR-808/Glades Road project was completed under- budget, with the savings, returned to the owner.


The I-95 Express Lanes Phase 3B-2 includes the design and construction necessary to convert the existing High Occupancy Vehicle (HOV) lanes to Managed Lanes in both the northbound and southbound directions of a 5.8-mile section of I-95 from just south of Glades Road to south of Linton Boulevard in Palm Beach County. In addition to the project improvements described at left, the project includes (and connect to “construction of a new pedestrian bridge construction of a new pedestrian bridge along Glades Rd over I-95, demo and reconstruct the Clint Moore Bridge Over I-95 and SFRTA, widening of 6 bridges, temporary and permanent retaining walls, sound barrier walls, sign structures, tolling gantries and associated infrastructure including toll equipment buildings, Intelligent Transportation System (ITS), and ramp (metering) signals for five interchanges between Glades Road and Linton Boulevard.

Design Challenges

The Diverging Diamond Interchange is the first DDI to be constructed in District IV for the Florida Department of Transportation. The main challenge was the multi-lane closures of the roads and the single-lane daytime closures. However, the redesign is expected to reduce congestion and give pedestrians and bicyclists more access.

project goals

The purpose of the 95 Express Lanes is to improve mobility, relieve congestion, provide additional travel options, enhance transit services, accommodate future growth and development in the region, enhance emergency evacuation, and improve system connectivity between key limited access facilities in South Florida
