Get from West Campus to Duke Hospital without touching busy Erwin Road.
Ride carefully on the sidewalk shortcut between Bostock and Old Chemistry. You will find yourself behind Duke Clinics on Research Drive. Proceed down Research Dr, past the old coal plant. Turn right at the off-road trail, proceed up hill to the right (stay on asphalt trail). You will come to a pedestrian plaza area, proceed straight along asphalt trail to the Duke Medicine Circle. From there, you can park your bike and walk through the Hospital/DMP/Clinic to your final destination.
