FROM: Jimmy L. Morales, City Manager
DATE: April 21, 2017
SUBJECT: Update on the FDOT /MDX I- 395/1- 95/SR836 Reconstruction Project
The purpose of this Letter to Commission (LTC) is to provide an update on the joint Florida
Department of Transportation (FDOT) /Miami -Dade Expressway Authority (MDX) planned
reconstruction of 1 -395, as well as partial reconstruction of 1 -95 and SR836. The project limits
are SR836 /NW 17th Avenue through the Midtown Interchange (I -95 /SR836 /MacArthur
Causeway) to the MacArthur Causeway Bridge for approximately three (3) miles in the east -
west direction.
The improvements to 1 -395 will include the following:
• Increased capacity (addition of a lane in each direction) as well as operational and safety
improvements
• Construction of elevated ramps to provide a direct link between 1 -95 and 1 -395
• Construction of a high -level signature bridge over Biscayne Boulevard
• Improvements to areas underneath the expressway (pathways and common areas)
• Reconstruction of 1 -95 mainline from NW 8th Street to NW 29th Street
The related improvements to SR836 will consist of the following:
• Increased capacity (one additional lane in each direction) and operational improvements
• New ramps to /from NW 12 Avenue
• New westbound ramps from 1 -95 to SR836
• Additional exit ramps at NW North River Drive
This project will be completed through a design /build /finance project delivery method as part of
a joint FDOT /MDX program. While the design /build contract be will awarded in Spring 2017,
construction is anticipated to begin in late 2017, and continue for approximately five (5) years at
a total estimated cost of $802 million. Similar to other FDOT Projects, City staff will work closely
with FDOT staff to provide input on the Maintenance of Traffic Plan, including scheduled lane
closure times and construction schedule, to help reduce traffic impacts to the City.
Please feel free to contact me if you have any questions.

PROJECT CHARACTERISTICS
The project begins on SR 836 at NW 17 Avenue and
continues through the Midtown Interchange (I-
95 /State Road 836/1 -395) along 1 -395 to the MacArthur
Causeway Bridge for approximately 3 miles in the east -
west direction. 1 -395 is an Interstate Principal Arterial
and a major east -west connector for the beaches and
port; SR 836 is a Principal Urban Arterial that is also a
major east -west connection to the Midtown
Interchange. The project limits also include 1 -95 from
NW 8 Street to NW 29 Street. SR 9A/I -95 is an Urban
Interstate Principal Arterial and major north -south
connector to downtown Miami. There are both dense
urban and residential areas within the project limits.
The project will address roadway safety, corridor
capacity, a variety of design issues, aesthetics, and
provide a Signature Bridge design over Biscayne
Boulevard.
1 -395 RECONSTRUCTION PROJECT
The 1 -395 portion of the project involves the rebuilding of the 1 -395 corridor
from the I -95 /Midtown Interchange to the MacArthur Causeway.
Project improvements include
• Increasing capacity
• Improving safety by alleviating
existing operation and
geometric deficiencies
• Building new elevated ramps:
one eastbound and one westbound,
link between 1 -95 and 1 -395
• Building a Signature Bridge over Biscayne Boulevard
• Building vertically higher structures that will improve the visual quality of the bridge and streetscape
• Improving the area underneath the expressway by providing pathways and common activity areas.
• Design /Build /Finance
that will provide a direct

The MDX 836 Improvements Project limits are NW 17 Avenue Interchange to the Midtown Interchange. Project
improvements include:
SR 836 WESTBOUND CONNECTOR
• Adds capacity to SR 836 mainline by adding a
lane in each direction improving mobility and
safety
• Provides a new elevated eastbound ramp from
NW 12 Avenue for traffic destined to
northbound and southbound 1 -95 and
eastbound 1 -395 separating these movements
from the SR 836 mainline to the same
destinations
• Provides a new elevated ramp from
southbound 1 -95 to westbound SR 836 with an
additional exit at NW North River Drive which
eliminates the traffic operational conflicts
between the westbound SR 836 exit to NW 12
Avenue and the 1 -95 southbound entrance to
westbound SR 836
The SR 836 WB Connector project includes the construction of a 9A/I -95 southbound ramp to westbound SR 836.
