On a ride yesterday to Hunter's Point, I found that the Illinois St. Bridge over Islais Creek is bikeable! The design may not be perfect, but they took bikes into consideration during the design and construction.
2. The southbound bike lane emerges from the shared bikepath/sidewalk as you leave the bridge and get back on the roadway.
3. Muni crosses Islais Creek on the 3rd St. Bridge, as seen from Illinois St. bridge
4. After passing over the Illinois St. Bridge, take a short ride down to the end of Cargo Way and check out the native plants at Heron's Head Park.
