[PRCo] One way streets

[Fred Schneider]

As an example of how early motor vehicle traffic was starting to be a  
burden in Pittsburgh ...

Penn Avenue became one-way west (from Ferry to 32nd) and Liberty one- 
way east (from Grant to 32nd) ..... way back in 1918.   That is when  
routes 86, 87, 88, 94 and 95 became inbound on Penn and outbound on  
Liberty.   Today we call Ferry Stanwix south of Liberty.   North of  
Liberty Cecil Alley became Stanwix.

That fits in very well with my earlier suggestion that the city  
probably wanted cars off the streets and onto loops instead of  
changing end in the middle of streets.

I still have not found when Wood and Smithfield became one-way  
streets, or perhaps I just have not been sufficiently observant.
