I-707's southern terminus is a modified trumpet interchange with Route 65, near the Parktown and South Empire neighborhoods of southeast Ithaca. The interchange allows access from I-707 to Route 65, as well as Lawrence Avenue and Cairo Street, and indirect access to the Port of Ithaca; traffic from both directions of 65, as well as from Lawrence Avenue and the Port of Ithaca also have access to northbound I-707 through the interchange.
Just north of the southern terminus interchange is a partial cloverleaf interchange and overpass over Empire Boulevard. Here, I-707 serves as a dividing line between South Empire and Cooper Downs neighborhoods to the west and the Parktown neighborhood to the east. From here, I-707 crosses a rail line, then makes a slight westward curve and a downward slope.
I-707 has a major interchange with Interstate 7 and Ottawa Street, just east of the Armstrong Hill neighborhood in central Ithaca. On northbound I-707, exiting traffic for either direction of I-7 and Ottawa Street is split off, and then traffic entering I-707 from Ottawa Street, I-7 westward and finally I-7 eastward merge into northbound I-707. For much of this stretch, I-707 runs as an underpass under both lanes of I-7 above. Traffic from I-7 east to I-707 north merges at the Warsaw Street overpass bridge, adjacent to the State of North Heaven's Western Regional Government Center.
I-707 here runs along the eastern edge of the Ithaca State University campus, with a complete diamond interchange at West Lake Drive, and an incomplete diamond interchange at Athenian Street. I-707 then curves to the northwest, through an incomplete interchange with University Boulevard, and then curves due north.
I-707's northern terminus is a three-level semi-directional T interchange with Route 81, northwest of North Oaks, on the northeastern fringe of Ithaca.
