From streetcars to scenic Sunday drives, this episode looks at the transit projects that continue to shape our region. Episode four explains why the 40th Street Bridge has colorful seals; how the East Busway was routed and what led to those decisions; and we take a trip along Allegheny River Boulevard, complete with picnic pull-offs with picturesque views.(The Good Question!
