Master Plan Update - Florida's Turnpike

line, and merges into the right side of the
southbound heft mainline; (2) narrow the existing
three-lane ramp that enters the southbound heft to
two-lanes in order to maintain lane balance with
the southbound heft mainline roadway; and (3)
widen the southbound heft mainline (including the
bridge over the csx railroad) to add one-lane and
eliminate the existing southbound lane drop.
Implementation of this project will improve safety
and operations by eliminating the southbound s.r.
874 traffic weave across southbound HEFT lanes to
exit at sW 152nd street. It will also result in smoother
southbound traffic flows on the HEFT Mainline south
of s.r. 874, and provide a southbound heft mainline
capacity improvement that was deferred by the
postponement of the larger widening project. this
project is scheduled for construction in fY 2011.
427146-1
construct auxiliary lanes on the
heft from kendall drive to bird
road in miami-dade county.
This is an efficiency project to construct auxiliary
lanes in both directions on the heft/s.r. 821
between the kendall drive Interchange and the
bird road Interchange to create an eight-lane
roadway section. This improvement modifies the
existing bridge structures within the project limits by
reducing the inside/outside shoulders to allow for
four, 12-foot travel lanes with eight-foot shoulders.
this is a safety and operational improvement that
will eliminate or reduce the bottleneck for the
existing six-lane segment between kendall drive
and bird road. It will also eliminate congestion for
the northbound on-ramp merge on the heft at
kendall drive, and improve operations for entry and
exit movements at kendall drive. this project is
programmed for construction in fY 2014.
427685-1
construct auxiliary lanes on
the heft from nW 74th street to
nW 106th street in miami-dade
county.
This is an efficiency project to construct auxiliary
lanes in both directions on the heft between nW
74th street and nW 106th street to create an eightlane
section on the heft. the implementation of this
FY 2011 - FY 2035
improvement will reduce the potential for
bottlenecks in this section. It will also eliminate
congestion in the southbound on-ramp merge area
at nW 106th street and will improve operations for
entry and exit movements at nW 106th street. this
project is programmed for construction in fY 2013.
427689-1
modify the heft at the kendall
drive ramp Interchange in
miami-dade county.
This is an efficiency project to implement the
following modifications to the HEFT/Kendall Drive
Interchange: (1) widen the ramp terminal
intersection approach of the southbound exit ramp
to provide three southbound left-turn lanes for the
southbound to eastbound movement and three
right-turn lanes for the southbound to westbound
movement, (2) widen the ramp terminal intersection
approach of the northbound exit ramp to provide
two left-turn lanes for the northbound to westbound
movement and two right-turn lanes for the
northbound to eastbound movement, (3) remove
the slope protection under the heft bridge over
kendall drive on the north side and relocate the
westbound to southbound entry ramp to be
located behind the column line, and (4) widen
kendall drive westbound to four through lanes from
west of mills drive to meet the existing four-lane
section west of the heft southbound exit ramp
intersection. this project is programmed for
construction in fY 2014.
427690-1
Implement to/from south ramp
Modifications on the Seminole
expressway at aloma avenue in
seminole county.
This is an efficiency project to improve the to/from
south ramps on the seminole expressway/s.r. 417 at
Aloma Avenue. Specifically, this project includes
the following: (1) add a right-turn lane for the
northbound off-ramp approach to aloma avenue;
(2) provide extended storage on aloma avenue for
the eastbound and westbound left-turn lanes
entering the seminole expressway; (3) add a rightturn
lane on aloma avenue for the eastbound to
southbound movement entering the seminole
