The grade-separated part of the Inner Loop that is still open is highlighted in red.
The Inner Loop is a ring road around Downtown Rochester. The full loop used to be a highway, but the eastern section is being filled in and replaced by surface streets in hopes of more downtown and East End revitalization, to which the deep-cut highway was considered a literal barrier. The southern part of the Inner Loop is formed by 490, which has a spur west of downtown for the remaining Inner Loop highway, which now ends at Scio Street.
There is also a less formal Outer Loop formed by 390 and 590 that circles the city limits.
