These are the Final Construction Plans for the Collier Parkway at Livingston Road Intersection Improvements project, prepared by the Pasco County Board of County Commissioners in collaboration with Ayres Associates. The project involves constructing additional left and right turn lanes on southbound Livingston Road at the intersection with E. County Line Road and Collier Parkway. The project spans approximately 8.5 miles, starting at Station 0+00 and ending at Station 58+75.04, with work including milling and resurfacing, sidewalk construction, utility adjustments, signalization modifications, and drainage improvements. The project will involve roadway widening, adding 4' paved and unpaved shoulders, installing 5' sidewalks, and implementing various drainage and utility infrastructure upgrades.

The project is funded through Pasco County and involves multiple utility adjustments with companies like Duke Energy, Zayo Group, FTR, TECO-PGS, and Spectrum. The total project includes numerous pay items across categories such as maintenance of traffic, excavation, embankment, base group installation, asphalt paving, drainage structures, guardrail removal, sodding, and signalization. The design incorporates geogrid reinforcement in areas with organic soils, and the typical sections indicate design speeds between 30-35 mph with projected Annual Average Daily Traffic (AADT) ranging from 7,000 to 20,120 vehicles. The design year is 2041, with an estimated opening year of 2021, and includes comprehensive utility, signalization, and roadway improvement plans.
