Presentation To Miami-Dade County Freight Transportation Advisory Committee (FTAC) November 14, 2012 Dat Huynh, P.E., FDOT Project Manager Robert T. Carballo, P.E., C3TS Project Manager 1

PROJECT LOCATION Located in northern Miami-Dade County  Adjacent to City of Miami Gardens, North Miami  Beach, North Miami and the Golden Glades Community 2

BACKGROUND THE GOLDEN GLADES INTERCHANGE Serves as a regional hub for transportation in northeast  Miami-Dade County Connects local and regional travel between three  south Florida counties: Miami-Dade, Broward and Palm Beach Provides access to:  Interstate 95 (I-95)  SR 826 (Palmetto Expressway)  Florida’s Turnpike  SR 9, and  SR 7/US 441  SR 826/NW 167 th Street  Connects to the Park & Ride and  provides access to regional transit 3

NEED FOR PROJECT TRAVEL DEMAND & CAPACITY Golden Glades Interchange currently carries is over  400,000 vehicles per day with direct impacts on regional travel within the tri-county area Travel demand within the interchange is projected to  increase by approximately 50% by the 2040 year Critical movements experiencing heavy congestion with  insufficient capacity include: 1. SR 826 EB to I-95 NB 2. Turnpike SB to I-95 SB 4

NEED FOR PROJECT SAFETY 3,239 total crashes  between 2006 to 2010 20 fatalities  1,496 injury crashes  Predominant Crashes  Rear End – 44%  Side Swipe – 18%  Fixed Object – 12%  Angle – 10%  Economic Loss  Estimated at approx. $93 million Fatal Crash Locations 5

STUDY PURPOSE AND OBJECTIVES INTERIM IMPROVEMENTS (NEAR TERM CONSTRUCTION) Provide a direct connection for SR 826 (Palmetto Expressway)  eastbound to I-95 northbound Improve the Turnpike southbound to I-95 southbound  connection Develop interim improvements within the Golden Glades  Interchange to enhance safety, mobility and circulation ULTIMATE IMPROVEMENTS (CONSTRUCTED WITH SR 826 E-W PROJECT) Accommodate potential express lanes system and transit  enhancements connection to Golden Glades Interchange Addition of express lanes from SR 826 connecting to I-95 to and  from the north Enhance Turnpike Connector southbound to I-95 with possible  express lanes direct connection Establish an Ultimate Master Plan for the Golden Glades  Interchange 6

ALTERNATIVES CONSIDERED No-Build Alternative  Preliminary Interim Build Alternatives:  Presented at the initial Alternatives Public Workshop held on  May 03, 2012 Refined Interim Build Alternatives:  Presented at the Alternatives Public Workshop Update held  on August 21, 2012 Ultimate Build Alternatives:  Represents the Ultimate Master Plan for Golden Glades  Interchange Presented at both Alternatives Public Workshop  Documented as part of SR 826 PD&E Study  10

PROPOSED IMPROVEMENTS Interim Build Alternative 3A Key Features 1. Provide a direct connection from SR 826 EB to I-95 NB that consists of a reverse S-curve alignment 2. Widen the Turnpike Connector to provide two lanes from the Turnpike SB merging with the SR 826 EB to I-95 SB traffic 3. Replace the SR 826/NW 167th Street WB to I-95 SB ramp bridge to accommodate direct flyover connection ramp and SR7/US 441 NB lanes 4. Replace the SR 826 Connector Bridge over the direct flyover connection ramp and SR 7/US 441 NB lanes 5. Provide signalized dual left turn lanes from SR 826 EB to Turnpike NB 6. Widen I-95 SB from interchange to NW 151st Street to accommodate additional lane from Turnpike Connector 7. Provide connection from NW 163rd Street to NW 17th Avenue and widen NW 17th Avenue from NW 161st Street to SR 826. Access to SR 826 at NW 12th Avenue and NW 167th Street is removed 8. Right of way impacts to 2 commercial properties and 3 vacant parcels west of I-95 north of Biscayne Canal 11

PROPOSED IMPROVEMENTS Interim Build Alternative 3A SR 826/Palmetto Expressway Mainline and Off-Ramp to I-95 NB & SB Turnpike Connector Between SR 826/Palmetto Expressway and I-95 12
