Interstate 20



Interstate 20 (I-20) is an unfinished controlled-access expressway that is planned to serve the northeastern portion of the Athens Federation from Interstate 420. This highway has the Lake Technoblade Memorial Bridge which crosses the western portion of Lake Technoblade.

Route
The route currently starts at the northeastern corner of Interstate 420, the Athens Beltway, near the town of New Covington. I-20 starts near the "four corners" region of Athens, Dream, Alvin and Pripyat counties. Initially, despite being an east-west route, I-20 has a north-southward heading, and crosses Lake Technoblade via the Lake Technoblade Memorial Bridge. The bridge uses electronic toll collection; crossing the bridge costs $8 for cars and $15 for trucks and buses in both directions. The bridge is approximately 500 meters long. On the north side of the bridge, I-20 enters Ana County and has one interchange that leads directly to Anaville. It then turns to the east-west in which direction it was designated for. It then passes through downtown Karlsholt, before traveling through the nearby mountains and also passing by the eastern part of the city. I-20 then passes through Green Forest prior to crossing the Prime Sea Memorial Bridge. The Prime Sea Memorial Bridge opened in November 2021. From there, I-20 continues eastward to the Tundra Pike, which goes to Blarston-St. Dwights.

Like all other interstate highways in the Athens Federation, I-20 uses sequential exit numbering.
