Northside communities, including Allegheny Commons Park, have been/will be directly impacted by increased rail traffic with double-stacked trains, and changes to several Northside bridges that are included in Norfolk Southern's plan:
Brighton and North Avenues Bridge
Columbus Avenue Bridge
Pennsylvania Avenue Bridge
Merchant Street Bridge
West Park Pedestrian Bridge
To refresh on the background and the impact of Norfolk Southern's Pittsburgh Vertical Clearance Project, you may want to take a look at the website Rail Pollution Protection Pittsburgh (RP3).
RP3 was created by concerned Allegheny City Central neighbors. It is a group of Pittsburgh residents who are "committed to addressing the risk and negative impacts of rail proliferation where it conflicts with urban health, sustainability, and personal well-being."
