The granite markers of the unofficial (in Washington) Jefferson Davis Memorial Highway are at the center of the park surrounded by Confederate flags.

In the aftermath of the white nationalist Unite the Right rally in August 2017, a local Antifa group took credit for vandalizing the markers,[3] and there has been a nationwide call for removal of such Confederate monuments.

[12] In March 2016, the Washington State Legislature unanimously passed a joint memorial that asked the state transportation commission to designate what was left of U.S. Route 99, Highway 99, as the "William P. Stewart Memorial Highway" to honor an African-American volunteer during the Civil War who later became a pioneer of the town and city of Snohomish.

[14] In 1998, a city of Vancouver official quietly removed the marker of the Jefferson Davis Highway, from near Covington House at the north end of Main Street[15] and had it placed in a cemetery shed, in an action that four years later became controversial.

[21][22] Within months of the park's dedication in the Spring of 2008, it was vandalized; the billboard was torn down and thrown into a nearby creek.

[1][23] Even though the markers and flags are located on private property, they are and were intended to be highly visible (to all cars travelling Interstate 5).

Their visibility, and events in other parts of the nation regarding Confederate memorials, still make these symbols a local focus of strong emotions, especially in the aftermath of the white nationalist Unite the Right rally August 11–12, 2017.

[27] The local Division Commander of the Sons of Confederate Veterans spoke of bringing in private security to prevent more vandalism; their leadership said they have received death threats over the monuments, "amid a tide of calls to remove Confederate monuments in the wake of Charlottesville violence of August, 2017".

[15] On October 2, 2017, the commissioners of the city of Ridgefield officially and unanimously asked the Clark County Historic Preservation Commission to remove the Jefferson Davis Highway marker, from Vancouver, Washington, from its local heritage list, which the Commission did.
