I-95 Express Lanes Phase 3A-2

Project Detail

The project included 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 7.4-mile section of I-95 from north of Commercial Blvd to the south of SW 10 St in Broward County, FL. The Express Lanes were implemented congestion-based toll pricing along the corridor.

Project Highlights

Project improvements included milling, resurfacing, and overbuilding of the existing I-95 travel lanes and shoulders, roadway widening, guardrail and barrier wall installation, drainage improvements, construction of two new ramp bridges, replacement of the pedestrian bridge over I-95, widening of 16 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 4 interchanges from Cypress Creek Road to Sample Road.

  • Extension of the existing north express lanes plus an additional lane will be added.
  • High Occupancy Vehicle (HOV) lane will be converted to create two express lanes in each direction.
  • Installation of Intelligent Transportation System (ITS) and tolling equipment.
  • Widening bridges and installing noise barrier walls.
  • Ramp signalization.

Client: Florida Department of Transportation

Location: Pompano, Florida

Area: 1.690 Square Meter

Finished: 2019

Cost: $154 Million

Remarks: It was completed approximately 5 to 6 months ahead of schedule while also meeting every milestone and planned incentives.

description

This project converted the existing high occupancy vehicle lanes to tolled express lanes adds one additional tolled express lane in each direction in conjunction with three to four general use (GU) lanes (existing) in the project limits. The project also consists of approximately 90 thousand tons of asphalt overlay to the existing lanes in order to shift the existing crown point, 16 bridge widening, 2 new concrete bridges, 1 new pedestrian bridge, drainage improvements, shoulder mounted sound walls, 4 ground mounted sound walls, signing, lighting, installation of new intelligent transportation system (ITS) infrastructure, 3 new tolling facilities with gantries, 4 ramp metered intersections and complete oversight of asset management during construction.

Also, in charge of monitoring the pre- and post-storm events for Hurricanes Matthew and Irma and preparing supplemental agreements for associated costs and time. The bridges consisted of 24” prestressed piling, footings, columns and caps. The superstructure utilized Type II AASHTO beams for the widenings and 45” Florida “I” beams for the new bridges. Span lengths typically observed were around 110ft for the new bridges and 60ft to 80ft for the widening. Part of the project also included a new 261 ft-long steel pedestrian bridge that spanned I-95 in two, 130 ft-long sections.

the challenges

While the department made every effort to minimize impacts to motorists, it was necessary to close travel lanes and detour traffic at various times and locations to complete project-related work safely.

project goals

The goal of the I-95 Express is to keep traffic moving at an average speed of 65 mph in the express lanes. Toll rates are displayed on electronic message signs so motorists can choose to use the Express Lanes or stay in the non-tolled general use lanes. Tolls are collected electronically by an “open road tolling” (ORT) system – no toll booths and no stopping to pay.
