History
As an Interblox
Old Interblox 58 (1950s-????)
Interblox 58 used to link an area north of Pacifico and south of Arsenal City to an area north of Storm Valley but south of Seaboard City via Nikilis City.
New Interblox 58 (????-2008)
Interblox 58 now links the Green Coast of Blockfield to Ocean City.
Demotion of Interblox 58 from Interblox to Highway
When the Robloxian Association of State Highway and Transportation Officials (RASHTO) traveled on this Interblox in 2008, they realized this Interblox did not meet construction requirements for it to be an Interblox. An EF0 tornado was responsible for this demotion. It touched down near the main runway at North Coast International Airport. The tornado traveled nearly a mile, before reverting back to a funnel cloud near Interblox 58. They then contacted The Robloxian Highway Administration to see if Interblox 58 had retrieved a waiver from them, to which the Robloxian Highway Administration said no. As a consequence, they told Blockfield to demote Interblox 58 to Highway 58. Blockfield strongly supported the demotion, and on an unknown date in 2008, the Interblox was demoted to a highway.
As a highway (2008-present)
Highway 58 follows the secondary original routing of Interblox 58 prior to its demotion from Interblox.
