The project is made up of two components:
- The construction of the Gateway Expressway, which will provide express connections from US 19 to I-275 and from the Bayside Bridge to I-275.
- The widening of I-275 to create express tolled lanes (one lane in each direction) from south of Gandy Boulevard to 4th Street North.
- Construct SR 690, a new 4-lane tolled expressway connection from US 19 to west of I-275. 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.
- Reconstruct existing Roosevelt Boulevard from the Bayside Bridge to Ulmerton Road.
- Reconstruct sections of existing US 19 and 118th Avenue North, including new ramps and flyover structures.
- Include various improvements to interchanges, intersections, and ramps within the project limits.
- Construction of a new airport access road parallel to SR 686.
- Construction of a new signalized intersection at Terminal Boulevard.
- Construction of a permanent roadway connection at Fairchild Drive north of the existing signal at Airport Parkway from Westbound SR 686.
