Frontage Road Closure between CR18 and River Ranch Parkway

Hide Featured Image

In January (likely starting January 3) there will be a full closure of the Frontage Road between CR18 and River Ranch Parkway. In mid-December, CR3 was opened with complete access at CR18. 

Proposed detours north/south:

  • I25
  • (neighborhood access) CR3

Project Timeline: January - May 31, 2023. 

Purpose of Project:

For improvements to the Frontage Road including grading, widening with curb and gutter, turn outs for future development, including safety improvements for ingress/egress off the Frontage Road, and improved sight lines. Travelers by the area can expect to see a lot of dirt moving as the biggest part of this project is is the full removal of the existing Frontage Road surface to River Ranch Parkway south about 1,600 feet to change the grade of the road.
