About this file
This is a typical sections drawing for a road construction project prepared by Walton County, Florida, and designed by HALFF Associates with engineer Aaron Harrison, P.E. The project involves the construction of a northbound right-turn lane at the intersection of U.S. Highway 98 and County Road 393 South in Santa Rosa Beach, Florida. The scope of work includes approximately 250 linear feet of new turn lane paving, drainage enhancements, clearing and grubbing, and installation of approximately 30 linear feet of retaining wall within the existing right-of-way. The project is divided into multiple construction stations with typical sections ranging from STA. 1+02.13 to STA. 3+52.64, featuring 10-foot widening sections with new asphalt pavement construction and resurfacing of existing roadway. The contract duration is 120 days to substantial completion with an additional 30 days for punch list completion.
The construction specifications detail pavement composition including 1.5-inch SP 9.5 surface course and 2-inch SP 12.5 structural course with optional base group selections, placement of performance turf sod, FDOT Type F curb and gutter installation, and Alabama Class 2 rip rap protection over D-2 filter fabric. All work must comply with FDOT standards and specifications, with final surface asphalt placed using a material transfer vehicle and static compaction only. The design speed is 40 to 35 miles per hour with posted speeds of 30 to 25 miles per hour, and a clear zone of 6 feet is established for the project. Material testing shall be performed in accordance with FDOT standards, and all milled asphalt becomes the property of the Walton County Road Department for delivery to 376 State Road 65 North, Eastpoint, Florida.
