Project Details
Work Type New Tolled Roadway
Phase Construction
Project Start August 21, 2017
Construction Cost $545 million
Estimated Completion Late 2021
Contractor Archer Western - de Moya Joint Venture

The Gateway Expressway project will create two new 4-lane elevated tolled roadways that will provide direct connections - with no intersections - between US 19 and I-275 and between the Bayside Bridge (north of 49th Street N) and I-275.

Also, I-275 will be widened to add one toll lane in each direction next to the existing freeway lanes from south of Gandy Boulevard to 4th Street North.

The project is made up of two components:
1) Construction of the Gateway Expressway
2) Widening of I-275 to create express tolled lanes.

Final design work continues. Construction is underway in some areas and will be more widespread throughout the project area as designs plans are approved. Additional details will be available here as construction activities change.

This project is a design-build project, which means that an overall concept of the design was put out to bid with many design requirements specified in a Request for Proposals. The successful contractor was chosen from a number of qualified firms bidding on the contract based on a design that met the requirements and is the most economical to construct. The contracting team that has been selected has now begun the final design (with its own or contracted licensed engineers) under the same contract time that includes the construction. This allows the contractor to begin working on specific items of work as portions of the design are completed and approved.

The design-build method gets projects to construction sooner than the traditional design-bid-build contracting where all of the final design is completed before the project is advertised for contractors to bid on the construction contract.

Overall, the Gateway Expressway project will change the existing roadway system in order to enhance safety, add capacity and improve mobility. The project will:

  • Construct SR 690, a new 4-lane tolled expressway connection from US 19 to west of I-275. This segment of roadway will generally be located in the median of existing 118th Avenue North (CR 296) and includes flyover bridges connecting to mainline US 19, structures over crossroads and sensitive lands, viaducts over surface roads, ramps, and widening and rehabilitation of existing structures that will remain. SR 690 will be elevated over portions of 118th Avenue North, 49th Street North, 47th Street North, 43rd Street North, 34th Street North, the ramp at 31st Court North and 28th Street North. The tolling will be "static" - meaning the cost will remain the same at all hours.
  • Construct SR 686A, a new 4 lane elevated tolled (static) expressway from the Bayside Bridge (CR 611) to just west of I-275. SR 686A will generally be constructed within the median of SR 686 (Roosevelt Boulevard) from the Bayside Bridge to SR 688 (Ulmerton Road), with a new interchange at SR 688, then will continue south along a new alignment through the old Sunshine Speedway property until it merges with SR 690 via flyover bridges and continue east toward I-275.
  • Reconstruct existing Roosevelt Boulevard from the Bayside Bridge to Ulmerton Road as generally two one-way surface roads including a new access configuration and roads for the St. Pete-Clearwater International (PIE) Airport terminal.
  • Resurface 118th Avenue North pavement, from US 19 to 31st Court North.
  • Reconstruct/widen/rehabilitate sections of existing US 19 and 118th Avenue North, including new ramps and flyover structures.
  • Mill and resurface the entire eastbound off ramp from SR 690 to southbound I-275.
  • Include various improvements to interchanges, intersections, and ramps within the project limits.

Work located in front of the St. Pete-Clearwater International (PIE) Airport includes:

  • Construct a new airport access road parallel to SR 686.
  • Construct new airport ponds.
  • Furnish and install a complete lighting system in the airport right of way to illuminate the new airport access road.
  • Construct a new signalized intersection at Terminal Boulevard.
  • Construct a permanent roadway connection at Fairchild Drive north of the existing signal at Airport Parkway from Westbound SR 686.

The project component (FPID 424501-2) along I-275 includes the design and construction of tolled express lanes in each direction from south of Gandy Boulevard to north of 4th Street North. The tolling will be "dynamic" - meaning the cost will vary throughout the day based on traffic demand.

All tolls will be collected electronically using the SunPass pre-paid toll program.

SR 690 and SR 686A Tolls
Tolling will be "static." This means the cost will remain the same at all hours of every day.

I-275 Express Lanes
Tolling will be "dynamic." Express lanes are dynamically priced to maintain steady traffic flow in the lanes.  Prices change based on the amount of traffic in the express lanes. With dynamic pricing, prices increase as the express lanes become more congested and decrease as congestion goes down. Dynamic pricing is designed to provide more predictable travel times, particularly during peak travel periods.
