New York State Route 297 (NY 297) is a state highway in the western suburbs of Syracuse, New York, in the United States. It is signed as north–south; however, it follows more of a southwest–northeast alignment for through the towns of Camillus and Geddes. The southern terminus of the route is at an intersection with NY 173 in a section of Camillus known as Fairmount. Its northern terminus is at a junction with State Fair Boulevard in Geddes, where NY 297 connects to Interstate 690 (I-690) exit 7. NY 297 passes through the northern portion of the village of Solvay and runs adjacent to the New York State Fairgrounds north of Solvay. The route was assigned in the late 1950s. Route description NY 297 begins at an intersection with NY 173 in Fairmount, a neighborhood within the town of Camillus. It heads to the northeast as the two-lane Milton Avenue, running alongside the main line of the Finger Lakes Railway and serving several commercial buildings in an otherwise residential area. After , the route passes under NY 5, here a limited-access highway. There is no connection between NY 297 and NY 5; however, NY 297 does connect to nearby NY 695 by way of Horan Road, a local street just north of the NY 5 overpasses. The route continues northeastward into the town of Geddes and the village of Solvay, where it passes by a mixture of homes and businesses as it slowly turns to the east. The highway continues to follow Milton Avenue along the northern fringe of the village to a junction with Bridge Street. At this point, the route turns to the north, following Bridge Street as it begins to slowly head downhill from the village. NY 297 immediately crosses the Finger Lakes Railway at-grade before leveling off as it leaves the village limits. The road soon rises again, however, climbing in elevation to cross the CSX Transportation-owned Mohawk Subdivision by way of a long, high bridge that curves to the northeast while crossing the tracks. On the other side of the structure, the route descends one final time, heading generally northeastward along the eastern edge of the New York State Fairgrounds and the western edge of a pair of large industrial plants. NY 297 crosses CSX's Fairgrounds Subdivision line at-grade in its final few yards before ending at an intersection with State Fair Boulevard (NY 931B)
