New Jersey Roads - Route Log - Multiplexes - 78/139
I-78/NJ 139 Multiplex
Until 1988, this was I-78 and Business US 1 multiplexed.
78/139 meet in Jersey City.
The first signal on both 78 east and 139 east, which only have signals here on the Holland Tunnel approach. Usually 139 and 78 run on separate signal phases, meeting for the first time east of this intersection (Jersey Ave.), but during construction they ran on the same phase. Perspective is from 139 east.
Former signage on 78/139 west where they split. Neither is signed because the highways were originally constructed as US 1/9 Business (now 139) and NJ 700N (Newark Bay Extension of the NJ Turnpike, now 78).
An older look west at the 78/139 split. Taken 3/2001 by David Greenberger.
Former sign on 139 west leaving 78. Due to construction it has been removed, and may not be replaced because this is not the actual beginning of 139.
