What it does

This final rule makes the following changes to the National Network (NN) in Syracuse, New York: the de-designation of the segment of the NN from Interstate 81 (I-81) between the New York, Susquehanna, and Western Railway bridge and the I-81/I-690 interchange (I-81 Viaduct); and the addition to the NN of the signalized surface urban arterial roadway system (Community Grid) that replaces the I-81 Viaduct and is designated as part of Business Loop 81 (BL 81). The remainder of I-81 between the I-81/I-690 interchange and the I-81/I-481 interchange (Exit 29) will be reclassified as BL 81 and remain on the NN. Interstate 481 (I-481) will be reclassified as I-81 and will remain on the NN. This rule will become effective immediately.
