By 1956, most limited-access highways in the eastern United States were toll roads. In that year, the federal Interstate Highway System was established, funding non-toll roads with 90% federal dollars and 10% state match, giving little incentive for states to expand their turnpike systems. Funding rules initially restricted collections of tolls on newly funded roadways, bridges, and tunnels. In some situations, expansion or rebuilding of a toll facility using Interstate Highway funding resulted in the removal of existing tolls. This occurred in Virginia on Interstate 64 at the Hampton Roads Bridge-Tunnel when a second parallel roadway to the regional 1958 bridge-tunnel was completed in 1976.
