Corridor Study
2018 Corridor Study Vision
Commercial Access Corridor
78% in favor of one directional vehicle lane
Public Feedback:
Calmer Traffic
More Walkable
Street Character
Two directional lanes would take away desired characteristics and add cost.

Conclusion
2018 Corridor Study recommended single lanes
Enhanced safety
Encourages pedestrians and bikes
Creates the recommended commercial street character
Single lane roundabout options meet the 20-year traffic projections
Single lane corridor will eventually reach capacity.
The three-leg option:
Most cost effective
Least environmental and property impacts
Four-lane corridor
Diminishes corridor safety and character
Increase Phase 1 cost by at least $3 million
Increase overall corridor cost by at least $10 million
Higher impacts to residences, commercial properties, and environment
Increased project duration
