Editing Interstate 20 (section)

==Auxiliary routes==
Two I-420s were planned but never completed or built. [[Interstate 420 (Louisiana)|One]] was to be a [[Bypass (road)|bypass]] around [[Monroe, Louisiana]], but was never built. [[Interstate 420 (Georgia)|The other I-420]] was planned as a bypass to the south of [[Downtown Atlanta]]. Due to [[Atlanta freeway revolts|anti-freeway sentiments]], this I-420 was never completed, and the already-built portion has been signed as [[Georgia State Route 154|State Route&nbsp;154]] (SR&nbsp;154)/[[Georgia State Route 166|SR&nbsp;166]], named the [[Langford Parkway]] (formerly the Lakewood Freeway).
