5 Sidewalk-Level Bike Lane Concept
West of Malt
• Remove/Relocate Sidewalk Obstructions
(poles, cabinets, pull boxes, trees)
• Reconstruct Sidewalks & Driveways to
provide a Shared-Use Bike/Pedestrian
Path
6 Sidewalk-Level Bike Lane Concept
East of Malt
• Extend the Existing Curb a Few
Feet into the Street
• Reconstruct Sidewalks &
Driveways to provide a
sidewalk-level Bike/
Pedestrian Path
7 Sidewalk-Level Bike Lane Concept
Extend existing curb
into the street
Maintain existing onstreet parking lane
(reduce from 11’ to 8’)
Construct 4’ pedestrian
path next to curb
Construct 5.5’ bike path
Maintain 4’ wide
landscape strip for
vertical features
and utilities
Driveway Sight
Constraints East of Garfield
Issues:
• Bike path not Standard Design width
(even with widened parkway)
• Poor Visibility of Cyclists at Driveways
• Curb-side bikes in dooring zone
• Low curb / drainage problems
• ADA compliance
• ROW impacts at driveways
• Truck loading blocking bike path
• Major utility relocation
• Project delays for utility coordination
• Cost ~$33M
