The Gateway Expressway project is a $545-million-dollar design-build project consisting of the design and construction of SR 690, a new four-lane tolled (static) expressway connection from US 19 (SR 55) to west of I-275 (SR 93); SR 686A, a new four-lane elevated tolled expressway running from the Bayside Bridge to I-275, this includes the reconstruction of the existing SR 686 from the Bayside Bridge to SR 688 as two one-way surface roads, including new access configuration and roads for the St. Pete-Clearwater International Airport terminal; and, the design and construction of tolled (dynamic) Express Lanes along I-275 from south of Gandy Boulevard to north of 4th Street North. Major Project features include: 19 new bridges, widening of six bridges and replacement of one bridge barrier, miscellaneous structures including permanent/temporary walls, noise walls, sign structures including cantilevers, overhead signs, mast arms, Intelligent Transportation Systems (ITS), and toll Gantries.
BCC’s TEO group lead the design efforts for Signing & Pavement Markings (S&PM), Signalization and ITS. Signing and Pavement Markings design included 118th Ave, SR 690 and I-275 which included Express Lane signing and marking. Signalization design included the Reconstruction of 9 existing signals along the project, design of a HAWK signal and temporary signalizations. ITS design included approximately 22 miles of conduit and fiber installations, 20 Close-Circuit Televisions Cameras (CCTV) and 21 DMS, Arterial DMS and Express Lane DMS, MVDS for Express and General Lanes, and Bluetooth Travel Time Devices.
