In 2023, the National Park Service (NPS), in partnership with the Federal Highway Administration (FHWA), launched a four-year, $123 million project to restore the historic Colonial Parkway.

Funded by the Great American Outdoors Act (GAOA), this once-in-a-generation investment will restore and extend the life of approximately 10 miles of the Colonial Parkway. The work includes:

• Rehabilitating pavement and shoulders

• Repairing 11 bridges and the Williamsburg Tunnel

• Improving drainage and stormwater systems

• Upgrading signs and guardrails

— all while preserving the aesthetic integrity and historic character that makes this road so unique.

The Parkway Rehabilitation is in its final phase

Please Note: Starting on or about Wednesday, September 9, the section of the Colonial Parkway between Fusiliers Redoubt Ramp and Penniman Road at Rt. 199 will close so construction can resume. This area had been temporarily reopened in June to accommodate increased visitation for summer Signature 250th events. The work is expected to be completed by fall 2026.

We truly appreciate the public’s patience and support as we undertake these once-in-a-generation improvements. Our priority remains delivering a high-quality Parkway that will serve the public for years to come.

Project FAQS

What is the Colonial Parkway Rehabilitation Project?

The Colonial Parkway Rehabilitation Project is a once‑in‑a‑generation investment to restore and extend the life of approximately 10 miles of the Colonial Parkway. Much of the Parkway’s infrastructure is approaching 90 years old, and comprehensive rehabilitation is needed to address aging systems, improve safety, and preserve its historic character.

The project includes:

• Rehabilitating pavement and shoulders
• Repairing 11 bridges and the Williamsburg Tunnel
• Improving drainage and stormwater systems
• Upgrading signs and guardrails

— all while preserving the aesthetic integrity and historic character that makes this road so unique.

Rehabilitation work will:

• Eliminate hazards such as potholes and settlement
• Strengthen bridges and drainage systems
• Improve tunnel lighting
• Preserve the Parkway’s iconic appearance

The result will be a safer, smoother, and more scenic experience for the next 40–50 years.

How was the project funded?

This work is funded by the Great American Outdoors Act (GAOA) Legacy Restoration Fund — a bipartisan initiative designed to tackle long-standing maintenance needs in national parks.

Colonial National Historical Park was successful in receving one of the largest GAOA transportation investments in the country. This project marks the first comprehensive rehabilitation since the Parkway’s full length opened in 1957.

Who is doing the work?

This project is managed by the Federal Highways Administration (FHWA) in partnership with the National Park Service (NPS) through a design-build team that includes a prime contractor, design specialists, and approximately 30 subcontractors.

When will the Colonial Parkway fully reopen?

The Colonial Parkway is expected to fully reopen by fall 2026, once all remaining infrastructure and preservation work is completed. Some segments may reopen earlier if they meet required safety and quality standards.

Updates will continue to be posted on the project webpage and shared through email notifications as the work progresses.

What work still needs to be completed on the Colonial Parkway?

The park was awarded additional GAOA and Federal Lands Transportation Program funding to address other major infrastructure and deferred maintenance projects within the Parkway corridor. Additional time is also needed to ensure that the workmanship maintains the aesthetic craftsmanship and historic character the Colonial Parkway is known for.

• Jones Mill Pond Dam Rehabilitation Project: This earthen dam supports approximately 600 feet of Parkway roadway. Remaining work includes armoring the dam to modern standards and upgrading safety features such as monitoring devices and guardrails.

• Bridge Rehabilitation Projects: Multiple bridges require critical maintenance, including full deck replacement and masonry restoration, to extend their lifespan and improve overall safety.

• Aesthetic and Historic Character Work: Upholding the NPS standards for aesthetic craftsmanship and historical integrity that defines the Colonial Parkway has been a challenge. Portions of earlier work are being redone to meet National Park Service standards for aesthetic quality and historical integrity.

Completing these projects together reduces the need for future closures and helps preserve the Parkway’s historic character for generations to come.

Why is maintaining the Colonial Parkway’s historic character so important?

The Colonial Parkway is more than a road—it’s a living piece of American history and a cultural treasure. Listed on the National Register of Historic Places, designated an All-American Road, and celebrated as “one of the finest parkway archetypes in the country,” it offers visitors a one-of-a-kind experience.

Preserving its original design ensures that future generations can enjoy the same scenic beauty, craftsmanship, and historic character that make the Parkway extraordinary. Every rehabilitation effort honors its legacy while enhancing safety and durability for decades to come.

How will the project preserve the Parkway’s historic look and feel?

Maintaining the Colonial Parkway’s iconic aesthetic is a top priority. The project carefully replicates its historic exposed-aggregate concrete roadway, restores brick bridges and culverts, and safeguards the cultural landscape that makes this scenic route so unique. All improvements are designed to enhance longevity without compromising the Parkway’s character and timeless beauty.

What steps are involved in creating an authentic, historically accurate aggregate surface?

Exposed aggregate paving is a longer, more labor-intensive process than traditional blacktop repaving. This project requires full-depth roadway reconstruction, including subgrade rehabilitation and installation of the final exposed aggregate driving surface.

The NPS is committed to maintaining the same level of craftsmanship and aesthetic quality that the Colonial Parkway was originally built to. All new construction is held to these high standards to preserve the Parkway’s cultural and historic significance for future generations.

The goal: Ensure the roadway remains safe and durable for another 50+ years while preserving its historic character.

Which areas are currently closed, and what detours should I use?

All segments within the project limits are currently closed to traffic. Please follow posted detours and check the project webpage for the most up-to-date maps and reopening information.

What determines whether a segment can reopen?

Before reopening, each section must pass safety inspections and meet quality standards for aesthetic quality, historic character, pavement, drainage, bridges, and tunnel systems.
