40TH AVENUE NE BRIDGE REPLACEMENT Public Meeting No. 1 Public Meeting No. 2 Objective Objective • Introduction of Project Team • Recommendations based on • Information Gathering Information Gathering and Survey • • Navigational Clearances Navigational Clearances • • Functional Use/Typical Section Functional Use/Typical Section • • Sustainability/Resiliency Sustainability/Resiliency

40TH AVENUE NE BRIDGE REPLACEMENT Key Project Objectives • Navigational Clearance • Safety • Accessibility • Aesthetics • Sustainability/Resilience *Based on Survey and Public Feedback

40TH AVENUE NE BRIDGE REPLACEMENT Navigational Clearance (Arch is Illustrative)

40TH AVENUE NE BRIDGE REPLACEMENT Navigational Clearances - Existing

40TH AVENUE NE BRIDGE REPLACEMENT Clearzones/Sight Distances

40TH AVENUE NE BRIDGE REPLACEMENT Navigational Clearances - Recommended • Shifting Crest and Channel • Not Impacting Adjoining Residents • Channel Depth Verified by Hydrographic Survey

40TH AVENUE NE BRIDGE REPLACEMENT Navigational Clearances – Not Recommended • No Shift in Crest • No Impacts to Channel

40TH AVENUE NE BRIDGE REPLACEMENT Community Input Opportunity

40TH AVENUE NE BRIDGE REPLACEMENT Typical Sections (Widths are Conceptual) North South • Accessibility • • Safety Bicycle Buffers • • Aesthetics Maximizes Vertical Clearance

40TH AVENUE NE BRIDGE REPLACEMENT Typical Sections (Widths are Conceptual) North South • Accessibility • Median Separator • Safety • • Maximizes Vertical Clearance Aesthetics

40TH AVENUE NE BRIDGE REPLACEMENT Typical Sections (Widths are Conceptual) North South • • Accessibility Barrier-Seperated Sidewalk • • Safety Impacts Sight Distance • • Aesthetics Constrains Vertical Curve

40TH AVENUE NE BRIDGE REPLACEMENT Barrier Options NEW Crash Rated Barrier • Safety • Aesthetics

40TH AVENUE NE BRIDGE REPLACEMENT Lighting Options • Safety • Aesthetics • Meet AASHTO and FDOT Pedestrian Lighting Requirments • LED

40TH AVENUE NE BRIDGE REPLACEMENT Next Steps Implement Pedestrian and Bicycle Access • Impact – Bridge Closure of 4 – 6 weeks • Construction initiation in Spring 2019 for Pedestrian and Bicycle Access • Would serve as the first phase of Maintenance of Traffic during Construction Phase of the Bridge Replacement

40TH AVENUE NE BRIDGE REPLACEMENT Next Steps

40TH AVENUE NE BRIDGE REPLACEMENT Proposed Construction Sequence

40TH AVENUE NE BRIDGE REPLACEMENT Key Points • Navigational access of approximately 13 feet • Constructing new support elements in line with existing will provide for minimizing impacts for boaters during construction • Typical sections which provide for safety of all users • Developed features which enhance aesthetics • Develop Design which can be constructed while maintaining access during construction • A resilient design to maintain access during its’ service life • Survey Results will be posted after the meeting
