[4] The skyway soon ends with eastbound and westbound ramps at a cut in Bergen Hill and the four-lane highway passes under John F. Kennedy Boulevard.

[2] The road meets Concord Street, where there is an eastbound left lane exit and a westbound intersection.

[8][10] Ramps from the western end of 12th Street Viaduct connect to the upper level roadway at the top of Bergen Hill at the Palisade Avenue intersection.

Westbound ramp on north side is separated from the main highway by a reinforced concrete retaining wall; the eastbound ramp on south side is supported by reinforced concrete deck arch spans.

[13] The project included replacement of the concrete deck, retrofitting for earthquakes, repair of the substructure and superstructure, and construction of a shoulder on westbound 14th Street Viaduct.

[11] The elevated westbound Interstate 78 diverges from 14th Street Viaduct of Route 139 one block west of Jersey Avenue.

This segment of the route is under the jurisdiction of the Port Authority of New York and New Jersey and this area is also known as Boyle Plaza.

After Grove Street, the road crosses County Route 637 (Luis Muñoz Marín Boulevard) near the Newport Centre Mall just to the south.

From here, the concurrency enters the Holland Tunnel under the Hudson River, which carries two lanes in each direction.

The two-way, 12th Street Viaduct from Jersey Avenue to the top of Bergen Hill was opened July 4, 1927.

[8] In 1928, the completed lower level portion of the highway, along with Route 1 Extension on the eastern side of the Passaic River, was opened as the first part of the eventual high-speed connection between the Holland Tunnel and Newark.

[8] The Bergen Arches Expressway was proposed in 1989 by Governor Thomas Kean to connect the Jersey City waterfront with a new railroad line, which would provide access to the Meadowlands Sports Complex.

[27] This proposed highway was strongly supported by Jersey City Mayor Bret Schundler, who felt that the road could bring further development, as well as provide traffic relief to the four-lane Route 139.

[28] Both Jersey City mayor candidates in 2001 supported a transit line instead of a highway along the Bergen Arches.

[29] Plans for a highway along the Bergen Arches were dropped in 2002 as leaders of Jersey City, including Mayor Glenn Dale Cunningham, favored mass transit.

The agency agreed to pay $1.8 billion to partially fund rehabilitation to the Pulaski Skyway and Route 139, and other projects that it considers part of the larger distribution network in the Port of New York and New Jersey.

[31][32][33] The Route 139 project rehabilitated the eastbound side of Hoboken Avenue Viaduct and resurfaced the westbound roadway.

[36] The Pulaski Skyway reopened in mid-2018,[37] and the lower level of Route 139 was temporarily restored to four lanes in December 2018, but was partially closed again in early 2019.
