In order to educate the public about Menifee's past, the Menifee Valley Historical Association has partnered with the Riverside County Board of Supervisors and the City of Menifee Community Services Department to create and construct monuments throughout Menifee that identify places of historical significance.
Known as the Three Flags Highway because it ran from Canada through the US to Mexico, U.S. Highway 395 was designated a historic route.
This historic designation did not provide funds for signs to be installed along the route. It is up to counties, cities and communities to raise funds to install signs as this route goes through their area.
Since Menifee is one of the missing links along Highway 395, the Menifee Valley Historical Association is partnered with the City of Menifee to install Highway 395 signs at four locations in Menifee along Encanto Road and along Antelope Road.
