CONTI ENTERPRISES NEARS COMPLETION ON
PHASE TWO OF NEW JERSEY'S INTERSTATE 295
PROJECT. BY KAT ZEMAN

lthough the entire $900 million Direct Connection
project isn't slated for completion until fall 2021, phase
two along Interstate 295 in New Jersey is nearly 70
percent complete.
Edison, New Jersey-based Conti Enterprises is one of four general
contractors charged with construction improvements along the busiest and most congested interchanges in New Jersey. Conti is a multinational developer and builder of complex facilities and heavy civil
and transportation projects for both the private and public sectors.
Conti's portion of the mammoth-sized project involves the
reconstruction of Interstate 295, Interstate 76, New Jersey State
Route 42 and affected roadway segments traversing the boroughs
of Camden County.
"It's going to provide tremendous congestion relief to the commuters of south New Jersey and greatly reduce traffic accidents,"
Project Manager Greg Kerrigan says. "We have 250,000 vehicles traveling throughout and accidents were four times the state average in
the old configuration."
The original interchange, constructed between 1958 and 1961,
was insufficient to accommodate current traffic volumes and travel
speeds. In addition, failing levels of service on the interchange
ramps, combined with the congestion of local streets, adversely
affected the quality of life in the surrounding communities.
"It's called the Direct Connection because currently traffic north
and south on Interstate 295 does not continue through the interchange," Kerrigan says. "You have to get off the highway and then
get back on. It's a really goofy movement of traffic causing a lot of
those accidents."

Building Bridges
Direct Connection is a federally funded project
orchestrated by the New Jersey Department of
Transportation (NJDOT) to improve traffic flow
and safety along the ramps and bridges that
carry Interstate 295 traffic across Route 42 and
Interstate 295. Conti's $152 million contract involves reconstructing the roadway; installing
new utilities, sound walls and overhead signs;
asphalt work; and strengthening existing soil
conditions underneath structures.
Overall, the project includes more than six
acres of ground improvements, 186,000 tons of

new asphalt, excavating more than 500,000 cubic yards of soil and
installing 30,000 square feet of sheeting. Some of this work calls for
restriping, and barrier and sign installation along Interstate 295
along with building three bridges. Construction on two of the three
bridges is complete.
When the third bridge is completed in 2018, it will allow all
Interstate 295 northbound traffic to travel through a 500-foot-long
tunnel. "And then there are some ground improvements," Kerrigan says. "They are extensive because it's a very swampy area with
substandard soil and the bedrock is too deep to be feasibly reached.
So it's an extensive ground improvement scope."
