[PRCo] Three Sisters Britches

[Schneider Fred]

First mention I can find in 1928 of cars running over the new 6th  
Street (Roberto Clemente) Bridge is October 20th.

The Pittsburghbridges.com website shows the 7th Street bridge opening  
in 1927.   I can find a refernce to Brighton Road cars being diverted  
over it on January 3, 1927.

Still have not figured out 9th Street.

Stay tuned if anyone cares.
