This project consists of the widening and reconstruction of State Road (S.R.) 15/U.S. 17 from two lanes to four lanes from DeLeon Springs to S.R. 40.  A roundabout will be added at the intersection of S.R. 15/U.S. 17 and Spring Garden Ranch Road. In addition, drainage improvements and a shared use path (along the right side of the roadway) will also be included as part of this project.

Wildlife crossings are provided at the Deep Creek Bridges and approximately one-quarter mile south of the entrance to the Hear Island Conservation Area.
