s (HOV lanes), which begin in and near downtown and end at exit 5, an interchange with
US 19. The road becomes more suburban and rural as it continues to head north. It has two additional interchanges, Bellevue/West View and Camp Horne Road. After Camp Horne Road, there are no exits until its terminus later. The Interstate terminates at its parent,
I-79. Like the interchange with I-579, this is also a partial interchange. Traffic on I-279 is only permitted to exit northbound on I-79, while only traffic heading southbound on I-79 can exit on to I-279 south.
The section from exit 1B to exit 2B is also known as the North Shore Expressway.
History

I-279 was first proposed in 1958 to run along what is now I-79 between the current I-376 in
Carnegie and the current I-279 in Franklin Park. On October 2, 1972, its route was swapped with I-79, putting I-279 onto its current route, although only the downtown portion and the Fort Duquesne Bridge were built at the time.
[ ]
In 1973, the designation was extended from downtown over Parkway West (what is now I-376) to I-79.
This section became part of I-376 in 2009, and the I-279 signs were taken down there.
I-279 from Fort Duquesne Bridge to its current northern terminus in Franklin Park was approved on June 4, 1975, but constructed from 1985 to 1989, opening in its entirety with a Governor
Bob Casey Sr. ribbon-cutting on September 16, 1989. From 1997 to 2003, various ramps, the Fort Pitt Bridge, and nearby tunnels were reconstructed. A direct connection from I-279 south to I-376 east was opened in 2002.
A tragedy occurred on the reversible HOV lanes in 1995 when a negligent highway worker failed to close the outbound gates, leading to a head-on collision that killed six. In 2006, to help prevent a repeat of this incident, automatic ""fast-acting" gates" were activated at the southern entrances to these HOV lanes in Downtown Pittsburgh.
