Children's Hospital, like all of Philadelphia's medical institutions, is a major force in the local economy. But that doesn't mean the city should overlook the problems with the hospital's overall design. You can see the impact the garage will have on the river simply by walking the Schuylkill trail past existing garages at Walnut, Chestnut and Market Streets. Even though a rail line parallels the river, the Schuylkill's east bank is the only one of the city's three riverbanks not blocked by a highway.
