Inner Loop

The Inner Loop was a short freeway circling downtown Rochester. The eastern section was closed as part of the project to reconstruct Union Street as a two lane, two way street and make the area less intimidating to pedestrians.

The Inner Loop was concieved in the 1950s when Rochester's population was 33% higher than in 2000. The majority of the route was completed by 1965, but the western end was not constructed for at least a decade. Over the years, alterations have been made to the termini at both ends of the route.

The interchange with I-490 on the east end has been modified twice, first to construct a true freeway to freeway interchange (including extra ramps and right of way for planned I-390) and again to turn one of the ramps from the Inner Loop to I-490 east into a ramp from Byron Street, providing access from the local streets.

The project to reconstruction Union Street utilizes a connection to I-490 via a reconstructed Howell Street. The Inner Loop is realigned to end at Union Street.
