Project Schedule
April 2019 Public Workshop Findings
• Alignment 2b received the most public support• Decreasing motorist speed is a priority • Increasing bicycle and pedestrian safety is
important• Addition of green space is positive for the
neighborhood• The multiuse path should connect (now or in the
future) to neighboring areas • Opinions varied about parking options on the
street • Opinions varied about center turning lanes

Alignment Selection
• Broadly supported by public workshop attendees
• Provides sufficient capacity in the current year and future
• Reduces vehicle speeds and maximizes green space
• Signalized intersections at both interstate ramps
• Increases safety for all transportation modes
• Provides community green space as well as a buffer to existing homes
• Supports accelerated construction of the new bridge
• Facilitates multi-use pathway connections
