North Parkway Construction, News, and Impacts

Construction will occur in phases beginning with temporary road widening in the median along the northbound travel lanes and on two bridges between Route 123 and Spout Run. Construction will impact drivers and park visitors for the duration of the rehabilitation. A minimum of one lane of traffic in each direction will remain open at all times. The project is anticipated to be completed in late 2025.

Frequently Asked Questions (FAQs)

This project is the reconstruction of approximately 7.6 miles of the northern section of the GWMP between Spout Run and the I-495/Capital Beltway in Fairfax and Arlington counties, Virginia. This project will improve the driving experience, safety, and water drainage while retaining and enhancing the historic beauty and culture of the parkway.

This rehabilitation includes:  

  • replacing the asphalt pavement 

  • redesigning portions of the Route 123 interchange 

  • repairing stormwater management systems  

  • replacing and updating drainage inlets and culverts  

  • stabilizing erosion 

  • constructing turnarounds for emergency vehicles  

  • rehabilitating two historic overlooks 

  • lengthening entrance and exit lanes at some interchanges to improve traffic safety 

  • reconstructing stone walls and improving roadside barriers 

  • and re-opening historic views along the parkway

This project is the first rehabilitation in this section of parkway since it was completed in 1962. Once completed, this historic parkway will continue to provide a safe, scenic, and smooth experience for those who are using it to connect to our nation’s history or as a way to get to and from our nation's capital.

The National Park Service (NPS), in partnership with the Federal Highway Administration Eastern Federal Lands Highway Division (FHWA - EFLHD), continue the process of rehabilitating the northern section of the George Washington Memorial Parkway (GWMP).
The northern section of the GWMP, between Spout Run to I-495/Capital Beltway, is the busiest section of the parkway and serves about 26 million drivers annually. It is a four-lane divided scenic parkway that is listed on the National Register of Historic Places and serves as a major commuter route between northern Virginia and Washington, D.C., carrying roughly 70,000 vehicles per day. It also provides access to several recreational and historic sites along the roadway. The physical roadway is reaching the end of its lifespan in the northern part of the parkway. NPS wants to rehabilitate the historic parkway to provide a safe and scenic experience while extending its lifespan. This project will repair and rehabilitate deteriorating aspects of the roadway as well as implement safety improvements while preserving the cultural and historical characteristics of the parkway.

Construction activities are tentatively scheduled to begin in August 2022. The project is anticipated to be completed in late 2025.

In September 2018, the NPS achieved a major milestone project by completing an environmental review completed for the rehabilitation. The NPS completed an Environmental Assessment and analyzed public comments before deciding how best to rehabilitate the north section of the parkway.

The National Park Service's preffered alterntative for the is intersection is to consolidate Route 123 on-ramps to southbound GWMP at a new intersection east of Pine Tree Road (modified diamond interchange).  Conceptual map is depicted below.

This would:
• Realign entrance to the Route 123 eastbound on-ramp to southbound GWMP mainline. The roadway would be realigned to be opposite the consolidated off-ramp from southbound GWMP.
• Maintain tight northbound GWMP exit ramp to both eastbound and westbound Route 123.
• Remove existing ramps in the northwest quadrant of the interchange (Earth Tech 2005).
• Install SWM best management practices consistent with VDEQ requirements.

For more information see the Enivironmental Assessment document.
