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
