Roadwork and Construction
Roadwork and infrastructure improvements are part of the Town of Frederick’s ongoing investment in safe, reliable, and connected streets. This page provides up-to-date information on current and upcoming projects that may impact travel, including lane shifts, detours, and road closures.
These planned improvements support long-term mobility, safety, and infrastructure reliability for residents, businesses, and visitors. While construction can create temporary disruptions, each project is designed to strengthen Frederick’s transportation network and support the Town’s long-term goals.
Current Projects
The Town of Erie will be installing a sanitary sewer main near County Road 5. The construction will require a temporary closure of CR5, which may affect residents commuting in and out of the area.
What’s Happening? Claystone Construction is extending a sanitary sewer line to serve Erie’s Summerfield subdivision, near Wyndham Hill. Work will take place within CR5’s right-of-way, requiring temporary closure.
When? Construction is expected to begin on January 5, 2026, and last approximately 43 days. Final scheduling and work are being coordinated with Erie, Frederick, and CDOT. Electronic Message Boards will be in place two weeks before construction begins.
Detour: County Road 3.25 to County Road 16.5
Location: CR5 between County Roads 3.25 and 7, north of Highway 52
Sanitary sewer repairs will be completed in the Hidden Creek subdivision to address requirements identified by the St. Vrain Sanitation District. Residents can expect localized one-lane closures in active work areas as crews access the sewer line. Sewer service will be maintained throughout the project.
Where: The work will take place along portions of Fraser Street, Delores Avenue, West and East Big Thompson Circle, Big Thompson Court, Poudre Street, and a small segment of Arkansas Street.
When: Work is scheduled from January 5, 2026, through February 20, 2026.
Thank you for your patience as this necessary infrastructure work is completed.
Starting November 17, 2025, through early 2026, Carbide Street will be fully closed between Silver Birch Blvd. and Eagle Blvd. This closure supports utility work for the Town’s new Engineering & Public Works Facility at 7400 Eagle Blvd, including:
- Sewer line connection and extension
- Water line installation at the job site
Please plan alternate routes and follow posted detours.
2026 Pavement Maintenance Program
The Town of Frederick’s annual Pavement Maintenance Program is underway, with work planned across several neighborhoods and key roadways. This year’s project focuses on crack sealing, mastic sealing, and slurry seal treatments to extend the life of our streets and preserve Town infrastructure.
Treatment Definitions:
- Slurry Seal applications involve a thin mixture of asphalt emulsion and fine aggregate spread across the road to provide a fresh, skid-resistant surface and help extend pavement life.
- Crack Seal and Mastic Seal treatments fill existing cracks to prevent water intrusion and further deterioration.
Where We’re Working: Road maintenance locations were selected using our Pavement Management System, which helps Engineering and Public Works evaluate road conditions and prioritize projects that improve long-term road quality while minimizing future repair costs. Please view the Pavement Maintenance Program Map for work-area locations.
What to Expect:
While this work improves roadway safety and helps avoid more costly repairs in the future, in some areas, residents may experience temporary disruptions such as:
- Short-term traffic delays, detours, and lane closures
- Construction noise, dust, and equipment activity
- Restricted street parking near active work zones
How You’ll Be Notified:
- Contractors will deliver door hangers with detailed project information in advance of work.
- No parking signs will be posted at least 72 hours before construction starts.
- Town staff, alongside Frederick Police Community Service Officers, will work to notify owners of any stationary vehicles in the work zones.
Maintaining our roads is essential to building strategic, reliable, and sustainable infrastructure, one of the Town’s long-term strategic goals. Thank you for your patience as we continue investing in a safer, stronger transportation network.
As part of the Town of Frederick’s ongoing investment in safe, reliable infrastructure, the 2025 Pavement Maintenance Program includes targeted asphalt patching, mill & overlay, and roadway striping improvements throughout Frederick. These preventative treatments help preserve road quality, reduce long-term costs, and improve travel safety for residents and visitors.
Treatment Definitions:
- Patching addresses localized pavement failures by replacing damaged sections of roadway.
- Mill & Overlay removes the top layer of asphalt and applies a new surface to extend the life of the roadway and restore a smoother ride.
- Striping enhances lane visibility and safety by reapplying traffic markings.
