Cycling Options for GGB

1. Background Info

Structural Challenges on the GGB
• The bridge has narrow sidewalks with multiple challenges (Tower areas are only 5.5-7.5’ wide and have abrupt turns, other areas are only 5’ to 10’ wide. Other challenges include metal plates, poles, chain link fence sections, metal transition bumps, sudden width changes, overhanging railings, high noise levels making verbal warnings more difficult, etc.)

• High speed bike traffic is routed to sidewalks instead of roadway (and the roadway has extensive expansion joints with slots wide enough for bike wheels to drop in).

Resulting Issues
• Crashes
• Congestion

Related Causes
• Wind
• Slippery spots
• Speed, rider error
• Lane usage, stopping in lane
• Lack of markings
• High usage
• Tourists mixed with commuters/athletes

Very HelpfulHelpfulNeutralNot Helpful
Create a speed limit for bicycles on mixed pedestrian/cyclist East sidewalk
Create a speed limit for bicycles on bicycle-only West sidewalk
Paint a centerline and other markings to suggest two lanes on both West and East bridge sidewalks – 8’ or wider straightaways only
Use colored paint to mark the East sidewalk with a Pedestrian Zone next to the railing the length of bridge and a separate Roadside Zone in areas where sidewalk is at least 8’ wide. Restrict cyclists to the Roadside Zone where available. Restrict pedestrians to the Pedestrian Zone at all times.
Open West sidewalk more hours to limit commuter/high speed cyclist use of East sidewalk
Put key GGB crossing information in all bike rental packages, in multiple languages
