Driving across the commuter bridge that connects Marin County to the city of Richmond is not just a trip across the bay. It’s also a trip across a social divide. On one side of the bridge, Marin’s rolling green hills and roadside bird sanctuaries are laced with trails and encourage biking, walking and running. Fresh produce abounds in Marin. Drive over the Richmond Bridge, and you’ll find a very different environment. In poorer neighborhoods in Richmond, people are often afraid to walk outside or take their children to the park. Healthy food is harder to find. And these differences are reflected in the health of the residents on each side of the bridge.
