Henrico County is one of only two counties in Virginia that maintains its own roads, with the other being Arlington County. This special status was due to the existence of county highway departments prior to the creation in 1927 of the state agency that is now VDOT; and the assumption by that agency in 1932 of local roads in most counties. (Henrico and Arlington were grandfathered and allowed to continue pre-existing arrangements.) The control of the roads system is considered a powerful advantage for community urban planners, who can require developers to contribute to funding needed for road needs serving the planners' and developers' projects.
