Opened in 1968 as part of the initial 37-kilometer (23 mi) NLEX segment between Quezon City and Guiguinto, Bulacan, it was one of the first projects of the Construction and Development Corporation of the Philippines, now the Philippine National Construction Corporation (PNCC).

3. What is an Interchange?
Interchange is a road junction that uses grade
separation, and typically one or more ramps, to permit
traffic on at least one highway to pass through the
junction without interruption from other crossing traffic
streams.
it differs from a standard intersection, where roads
cross at grade.
The slip roads to and from the motorway carriageways
converge at a single roundabout, which is grade-
separated from the motorway lanes with bridges.

4. What Are the Types of
Interchange?
Directional Interchange Cloverleaf Interchange Diamond Interchange
Trumpet Interchange
Single Point Urban
Interchange (SPUI)
Road Signs At Highway
Interchanges
Directional Interchange

5. Directional Interchange
A directional interchange is placed at
an intersection of two highways
where a high volume of traffic
desires to transfer between only two
legs of the interchange. Directional
interchanges have increased ramp
speed and capacity and require less
space, when compared to a
conventional cloverleaf interchange,
but they are more costly to
construct due to an increased
number of ramps.

6. Cloverleaf Interchange
Probably the most common highway
interchange out there. Cloverleaf interchange is
designed to allow drivers to make turns off and
onto the highway from four directions using
loop ramps. Loop ramps safely accommodate
left turns and eliminates all cross traffic conflicts.

7. Trumpet Interchange
A trumpet interchange may be used
instead of a T-intersection when one
highway terminates into another highway.
A trumpet interchange may be seen as a
combination of a directional and a
diamond-shaped interchange.

8. Single Point Urban Interchange (SPUI)
A single point urban interchange is a traffic
signal-controlled diamond-shaped
interchange. Through traffic, traffic turning
left or off the interchange is controlled by a
single set of traffic signals that are located at
the top of the interchange. The design is
utilized at busy interchanges with limited
space available, it's main advantage is that it
allows opposing left turns to proceed
simultaneously.

9. Diamond Interchange
Diamond interchange design is utilized
when a busy freeway intersects with a
lesser road. Traffic leaves and enters
the highway through four ramps. Left
turns are made after leaving the
highway. Due to the limitations in
design, an increase in the volume of
traffic on the crossroad leads to
congestion and increased waiting time
for traffic leaving the highway.

10. Road Signs At Highway Interchanges
In order to assist drivers with navigating
complex interchanges, green guide
signs are installed on approaches and
directly at the interchange. Individual
guide signs may be installed above
separate lanes to let drivers traveling in
the lane know their options.

12. THE BALINTAWAK
INTERCHANGE
The balintawak interchange, also known as the
balintawak cloverleaf
● Two-level cloverleaf interchange in Quezon City,
Metro Manila, the Philippines which serves as the
junction between Epifanio De Los Santos Avenue
(EDSA) and the North Luzon Expressway (NLEX).
● Constructed in 1966 by the construction and
Development Corporation of the Philippines.

13. History Balintawak Interchange
● Opened in 1968 as part of the initial 37-kilometer (23 mi) NLEX
segment between Quezon City and Guiguinto, Bulacan, it was
one of the first projects of the Construction and Development
Corporation of the Philippines, now the Philippine National
Construction Corporation (PNCC).

14. Construction of Balintawak
Interchange
• Was precipitated by the large
number of motor vehicles in
Manila and the surrounding
suburbs in the 1960s, which
contributed to significant traffic
congestion. On june 25, 1966,
President Ferdinand Marcos
ordered the Department of
Public Works to undertake the
construction of a number of
road projects to be financed
through World War II
reparations, including the
construction of interchanges on
vital intersections along EDSA
● This order would later lead to the
construction of this interchange,
replacing a previous roundabout
between EDSA, Bonifacio Avenue
and the Quirino Highway, and the
Magallanes Interchange between
EDSA and the South Luzon
Expressway (SLEX), which opened
in 1975. A shrine to Andres
Bonifacio would later be
constructed inside the interchange,
which underwent a ₱13 million
renovation in 2009.

15. Disadvantages of Balintawak
Interchange
● Occupy too much land making them not ideal for
cramped places, and this type of interchange is
quite prone to weaving problems, where cars
leaving and entering one road weave in each others
paths, though the problem is not as problematic as
in a rotunda interchange
● Flooding in the area around the balintawak
interchange is a problem, with the interchange being
named in 2014 as one of the twenty-two most flood-
prone road ways in Metro Manila.

17. BALINTAWAK INTERCHANGE:
VOLUME:
With some 30,000 vehicles estimated to use the new
road daily during its first year of operation, since its
opening it has helped to relieve traffic on the
older Balintawak Interchange connecting Epifanio de los
Santo Avenue (EDSA) to the NLEx, which is three times
smaller.
LENGTH:
37-kilometer (23 mi) NLEx segment between Quezon
City and Guiguinto, Bulacan, it was one of the first
projects of the Construction and Development
Corporation of the Philippines, now the Philippine
National Construction Corporation (PNCC).
