Hiawatha Avenue (TH 55) Pedestrian/Bike Crossing Experience & Safety
Improvements Analysis
Background• Stonebrooke Engineering was hired by Hennepin County to evaluate pedestrian/bicycle crossing experience concerns at (3) key intersections along Hiawatha Avenue from E 32nd Street to E 46th Street
• Historical review of area improvements/analysis undertaken
• Technical Advisory Committee (TAC) formed to evaluate viability of identified improvement options– Hennepin County, City of Minneapolis, Mn/DOT, Metro Transit
• TAC/Resident concern noted• Potential feasible improvement projects identified
Key Project Issues
• Address pedestrian/bicycle crossing safety issues• Improve traffic signal timing• Decrease pedestrian crossing distances• Provide appropriately sized pedestrian refuge locations
• Incorporate improvements into greater area rehabilitation efforts
• Improved accessibility

45th/46th Street Project Issues
44th to 46th Street Improvement Options
• Pedestrian bridge/skyway‐ High cost ($2M+ expected)‐ Access ramp length (ADA requirements)‐ Unknown tie‐in locations (bridge)‐ Maintenance costs
• Pedestrian Tunnel‐ High cost‐ Not feasible (water table level)‐ Eliminates vehicle to pedestrian/bicycle interaction ‐ Maintenance costs
44th to 46th Street Improvement Options
• Pedestrian signal at 45th Street with median barrier from 44thStreet to 46th Street‐ Medium cost‐ Potential for low compliance by pedestrians and vehicles‐ Signal timing challenges (progression)‐ Maintenance costs
• Median barrier from 44th to 46th Street with no access points‐ Medium cost‐ Limits mobility‐ Funnels pedestrian/bicycles to traffic controlled intersection‐ Maintenance costs
44th to 46th Street Improvement Options
• T‐intersection at 44th/45th Street with full traffic signal‐ Low probability to meet traffic signal warrants‐ High cost ‐ Challenging signal timing (progression)‐ Access management/safety concern
• Do nothing option
‐ Low cost‐ Allow current mobility patterns
Next Steps
• Continue to explore 44thto 46th Street improvement options
• Public involvement• Develop implementation and design plan specifics and timelines
• Preliminary Design with engineered cost estimate(s)
