George Washington Memorial Parkway (Spout Run)- GWMP 1A108-LC (Phase 2)
Arlington County, Virginia
Rockfall mitigation along the northbound George Washington Memorial Parkway near the Spout Run exit
This section will be updated on a weekly basis.
The project is complete. All lanes are open to traffic.
Stabilize the rock slopes of two (2) sites that experienced recent rock fall events along the northbound GWMP at the exit of Spout Run Parkway.
- Site #1 – This site is located along the left side of the northbound lane of GWMP just south of Spout Run Parkway Exit. In early February 2011, this site experienced a number of rockfall events. Fortunately, the fallen rocks did not reach the roadway and no road closure was implemented. This site has experienced major rock failures in the past.
- Site #2 – This site is located along the left side of the northbound lane of GWMP just north of Spout Run Parkway exit. As a result of the 5.9 magnitude earthquake event on August 23, 2011, a boulder fell from the cut slope on the parkway causing traffic disturbance and road closure.
Construction began on temporary safety measures on November 7, 2011, and was completed by January 15, 2012. Phase 2 work to stabilize the slopes was completed on December 3, 2012.
