Under Construction

Project Update

Posted April 16, 2025

Construction started on April 16, 2025, and the project is anticipated to be completed in September 2026. There will be traffic impacts from 7 a.m. to 7 p.m. (Monday – Friday), and Saturdays as approved by the Engineer, except Douglas County holidays.

Please note that parking in the dirt area east of Legend High School is not permitted. This is Douglas County right-of-way. We ask that the public obey the no parking signs and park at the high school for related events. Cars parked in this area may be ticketed by the DC Sheriff’s Office.

Existing utility facilities and services are currently being relocated on the Hilltop Road corridor between Legend High School and Alpine Drive (this started in mid-March of 2025). There will be intermittent lane closures and some traffic impacts, however, most of the work is outside of the roadway.

Description

Background

In 2020, Douglas County began planning efforts to widen and improve Hilltop Road from Legend High School to Flintwood Road on Singing Hills Drive. It was determined that the current two-lane configuration could no longer effectively accommodate the larger traffic volumes. Improvements to this vital stretch of roadway will increase mobility and safety in the area – ensuring all road users can safely use the Douglas County facilities for years to come. The design life of this new roadway configuration is 20 years.

Project Overview (Phase 1) 

Douglas County will construct improvements to the existing Hilltop Road, between Legend High School and the Crestview Drive/Village Road intersection on Hilltop Road. The project consists of:

  • Widening the new roadway from two lanes to four lanes.
  • Improving curb and gutter.
  • Adding a raised median.
  • Constructing a new roundabout at Crestview Drive/Village Road on Hilltop Road, eliminating the existing two-way stop-controlled intersection.
  • Installing a new storm sewer system that will outlet into permanent water quality ponds adjacent to the roadway.

Phase 1 Schedule – Hilltop Road from Legend High School to Crestview Drive/Village Road

  • 2020-2022: Engineering staff advanced surveying, design, subsurface utility engineering and coordinated proposed utility relocations.
  • 2023-2024: Complete final design, continue ROW acquisitions, and begin proposed utility relocations.
  • 2024-early 2025: Complete utility relocations.
  • 2025: Construction of the project will begin (pending funding and completion of ROW acquisitions/utility relocations); completion of project will take 12 to 18 months.

Phase 2 Schedule – Hilltop Road from Crestview Drive/Village Road to Alpine Drive

  • 2020-2023: Engineering staff advanced surveying, design, subsurface utility engineering, and coordinated proposed utility relocations.
  • 2024-2026: Complete final design, ROW acquisitions, and utility relocations in advance of construction.
  • 2027: Construction is anticipated to begin in 2027 (pending funding); and will take 9 to 12 months to construct.

Phase 3 Schedule – Alpine Drive on Hilltop Road to Flintwood Road on Singing Hills Road

  • 2020-2024: Engineering staff advanced surveying, design, subsurface utility engineering and coordinated proposed utility relocations.
  • 2025-2028: Continue progress on other phases of the project, finalize design, acquire ROW, and relocate utilities.
  • 2029: Construction is anticipated to begin in 2029 (pending funding); and will take 12 to 18 months to construct.
