Today, US 46's western terminus is at I-80 and NJ 94 in Columbia; as a result, the 72-mile road no longer meets the criteria to be signed as a US highway, but it remains signed as such. After more than half a century known as "46", the state would likely rename the road NJ 46 if its US highway designation were ever stripped.
By a legislative act, the road is also called the United Spanish War Veterans Memorial Highway. However, old street names still exist in some sections. These are noted.
The mile markers here are from the road's western origination in Columbia. The road runs for 8.5 miles in Passaic County.
