I want to know the answer to the following question:
Of the 3.5 miles from N. Mountain Avenue to Rillito River Park, how many are bike-only?
All the background I'm provided with is that "To the North, N. Mountain Avenue has a full bike-only lane for half of the 3.5 miles (5.6 km) to the Rillito River Park bike and walk multi-use path.". Is that enough to answer the question?
Answer: yes
