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.
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.
The Parkway Rehabilitation Project is in its final phase. The project was originally anticipated to be completed by June 2026. However, several factors—including weather, the addition of new projects, and the complexity of meeting aesthetic standards—have impacted the original schedule. Full reopening is now expected by late fall 2026.
Why the change?
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.
Additional Improvement. Theseinclude rehabilitation of the Jones Mill Pond Dam and full deck replacement and repair of additional bridges. Completing this work now avoids future closures and ensures long-term benefits for all users.
Aesthetic Character. Upholding the NPS standards for aesthetic craftsmanship and historical integrity that defines the Colonial Parkway has been a challenge. Portions of previously completed work are being redone. While this adds time, these corrections will ensure a consistent, high-quality appearance and preserve the scenic beauty the parkway is known for.
We truly appreciate the public’s patience and support as we undertake these once-in-a-generation improvements.
What’s next?
We anticipate that some sections will be completed and reopened by summer of 2026, with the entire Parkway reopening by late fall of 2026. We will announce these openings on the project webpage and through email updates. Please continue to check back on this page as your primary source for updates and information.
Our priority remains delivering a high-quality Parkway that will serve the public for years to come. We look forward to welcoming you back later this year to once again enjoy the scenic and historic Colonial Parkway experience.

Current Project Timeline & Map
Below is the anticipated timeline for segment openings and closures. Please note that construction will temporarily pause in certain segments to accommodate increased visitation for this summer’s Signature 250th events*, including the Sail Yorktown Festival (June 12-14) and July 4th festivities. Construction in these areas will resume promptly after these events to help ensure project completion by late fall 2026.

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.
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 now expected to fully reopen by late fall 2026. This extension allows time to complete additional infrastructure needs and deferred maintenance projects, as well as rework in certain areas to meet NPS standards for aesthetic craftsmanship and historical integrity.
Some segments may reopen earlier once they meet safety and quality standards. Updates will be posted on the project webpage and shared via email notifications.
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.
What additional work is affecting the reopening date?
The reopening date was extended to accommodate additional major infrastructure projects funded through new allocations. Additional time is also needed to ensure the workmanship maintains the aesthetic craftmanship and historic character the Parkway is known for.
Jones Mill Pond Dam: This earthen dam supports approximately 600 feet of Parkway roadway. Work includes armoring the dam to modern standards and upgrading safety features such as monitoring devices and new guardrails.
Additional Bridge Rehabilitation: This project addresses critical maintenance needs on multiple bridges. Work includes full deck replacement and masonry restoration to extend lifespan and improve safety.
Aesthetic Character: The uniqueness of exposed aggregate paving over a 10-mile, three-lane corridor presented significant challenges. Portions of previously completed work are being redone to ensure the aesthetic quality and historic character the Parkway is known for.
By completing these projects now, we reduce future disruptions and closures and help preserve the Parkway’s historic character for generations to come.
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.
How will the Williamsburg Tunnel look different?
The tunnel is being rehabilitated with new LED lighting and structural repairs. These upgrades improve safety while respecting the Parkway’s historic character.
