Zone 1 is approximately two miles long and extends from west of I-75/Sawgrass Expressway to west of Flamingo Road on I-595.  Construction in Zone 1 is scheduled to begin in the summer of 2010.  Highlights from Zone 1 construction include: two new ramps to connect the I-595 toll lanes to the I-75/Sawgrass Expressway; widening the bridge over 136th Ave to the north; widening and relocating the existing westbound I-595 corridor to the north to accommodate three new toll lanes as well as new auxiliary lanes on I-595 mainline; construction of a tolling gantry east of 136th Ave; milling and resurfacing of existing I-595 lanes; and new asphalt pavement for additional lanes.   The work will also include some utility relocation, new signaling, lighting and striping.
