8. PROJECT BENEFITS
www.portofmiamitunnel.com
• Provide a direct connection
between the Seaport, Airport
and the Interstate Highway
System
• Maintain PortMiami as the
county’s second leading
economic generator
• Relieve congested downtown
Miami streets of Port
passenger and cargo traffic,
improving safety as trucks also
traverse areas of pedestrian
activity
• Facilitate ongoing and future
development plans in and
around downtown Miami
American Airlines Arena Bayside Marketplace

TUNNEL BORING MACHINE
• TBM cutter head with
an outside diameter
of 42.3 feet (as high
as a 4 story building)
• 361 foot long trailing
support gear made
up of 6 gantries
• Total length of the
TBM is 428.5 feet long
(more than a football
field).

BREAK-IN, BREAKOUT & TUNNEL
Mining of the Eastbound Tunnel began on November 11, 2011 and was
completed on July 31, 2012 (751 Rings & 4,186 LF)
Mining of the Westbound Mining began October 29, 2012 and was completed
on May 6, 2013 (745 Rings & 4,152 LF)

Tunneling Profile Section & Cross
Passages
• Tunnels are approximately 4200 ft. long
• +40 ft. under the bottom of Government Cut &
approximately 120 ft. below the surface at deepest
point
• 5% Grade
• 5 cross passages
16. www.portofmiamitunnel.com
CROSS PASSAGES
• Five cross passages, or emergency
exits, are being built between the two
tunnels.
• Cross passages are approximately 700
feet
• Cross passages 1, 4 and 5 are not
underneath the channel and were
pretreated from ground surface using
cutter-soil mixing panels that form a
grouted block of soil that can be
excavated.
• Cross passages 2 and 3, which go
underneath Biscayne Bay, are being
treated with a brine to freeze the
ground, before excavation is done.
CROSS PASSAGE
LENGTHS
• CP1 – 15 ft.
• CP2 – 36 ft.
• CP3 – 37.5 ft.
• CP4 – 43 ft.
• CP5 – 10.5 ft.
17. www.portofmiamitunnel.com
CROSS PASSAGES – GROUND FREEZING
PROCESS
• There are a total of 44 freezing pipes.
• Estimated freeze time once brine installed at -22◦F is 40 days.
• A small cooling unit is installed in the second tunnel to cool the
lining segments and ensure efficient “closing” of ice ring.
• Steel support frame is installed to prevent movements of the first
tunnel due to ice pressures.
• Steel door is installed as “fail safe” to be closed in case of an
emergency during excavation.

BORED TUNNEL TYPICAL SECTIONS
Two 12’ Travel Lanes
2’-6” Shoulders on both sides
2’-2” Maintenance Walkway in each Tunnel
Internal Diameter of Tunnel is 37’
Spacing between Tunnels varies from
21’ & 60’

TRAFFIC SURVEILLANCE & CONTROL
SYSTEM
The Traffic Surveillance and Control System (TSCS) consists of the hardware and software
necessary to monitor and control traffic and improve the safety and quality of traffic flow
by preventing or relieving congestion.
Primary Functions & Benefits:
• To provide efficient movement of traffic on and around the Project’s roadways
• To provide early detection of traffic incidents that cause slowdown and/or blockages
• To provide a systematic lane control for shifting or redirecting traffic through the roadways & tunnels
Components:
• Closed Circuit Television Cameras (CCTV)
• Vehicle Sensors
• Lane Use Signals (LUS)
• Dynamic Message Signs (DMS)
• Overheight Vehicle Detection (OHVD)
• Portal Traffic Closure Signas (PTCS)
• Automatic Traffic Control Gates
• Local Field Controllers (LFC)
• AM/FM Rebroadcast/Highway Advisory Radio (HAR)
• Fixed Signs

TUNNEL MECHANICAL/ELECTRICAL/ANCILLARY
BUILDING SCADA SYSTEMS
The SCADA system contains the computer hardware and software necessary to perform
all monitoring and control functions for the Mechanical, Electrical and Plumbing (MEP)
Systems.
“Monitoring & Controlling” functionality for following systems:
• Tunnel Ventilation
• AC & ID
• Tunnel/Stormwater Drainage
• Tunnel Lighting
“Monitoring Only” functionality for following systems:
• Carbon Monoxide Monitoring
• Fire Alarm and Detection
• Fire Suppression
• Hydrocarbon Monitoring
• Electrical Distribution
• Communications Systems
• Building Systems
23. www.portofmiamitunnel.com
UNIFIED OPERATOR INTERFACE
The Concessionaire will provide a unified operator interface that integrates the TSCS and
the Tunnel’s Mechanical/Electrical/Ancillary Building SCADA operator functions into a
single unified interface.
Unified Operator Interface Main Functions:
• TSCS and SCADA Alarm Notifications and Acknowledgement
• TSCS and SCADA System Device Control
• Cross Platform Alarm and Device Control between the TSCS and SCADA Systems
• Incident and Event Tracking and Logging

WATSON ISLAND – TUNNEL PORTAL
• Eastbound MacArthur
Causeway view
• Tunnel Portal houses the
Flood Gates which
come down in the
event of a storm to
prevent flooding of
tunnels
• Aesthetic challenge
was the massive size
and boxy shape of the
structure
