New York State Route 31B (NY 31B) was astate highway incentral New York in the United States. It served as a connector betweenNY 31, its parent route, in theCayuga County village ofWeedsport andNY 5 in theOnondaga County town ofElbridge. NY 31B was assignedc. 1933, replacingNew York State Route 293, a route assigned as part of the1930 renumbering of state highways in New York. The NY 31B designation was removed in 1980 and replaced by County Route 31B (CR 31B) in Cayuga County and CR 99 in Onondaga County.

NY 31B began at an intersection with its parent route,NY 31, in theCayuga County village ofWeedsport. The highway went eastward, intersecting withNY 34 less than 0.1 miles (0.2 km) later. Much of Weedsport was urbanized, with the highway passing residential homes and businesses as it progressed eastward through the village. The highway intersected withCR 12B before leaving Weedsport and entering the town ofBrutus as Brutus Road.[5]
In Brutus, NY 31B continued to the east through the rural town, intersectingCR 136A and passing the Weedsport Rural Cemetery before turning to the southeast. After a short distance, the highway went through an isolated area of homes, where it intersected withCR 14 andCR 15A.[5] NY 31B continued on, intersecting several local highways before crossing intoOnondaga County and terminating at an intersection withNY 5 in thetown of Elbridge.[6]
What became NY 31B was originally designated as NY 293 as part of the1930 renumbering of state highways in New York.[7] NY 293 was renumbered to NY 31Bc. 1933, allowing the NY 293 designation to be transferred toanother highway inOrange County.[2][3] NY 31B remained unchanged until January 2, 1980, when the NY 31B designation was removed.[4]
Ownership and maintenance of NY 31B's former routing was gradually transferred to the counties it went through, namelyCayuga andOnondaga. The first section to be transferred was the portion within Onondaga County, which was given to the county on April 1, 1980,[8] and designated as CR 99.[9] The Cayuga County section of former NY 31B was transferred to the county one year later on April 1, 1981,[8] and designated as CR 31B for the state route that preceded it.[10]
