For one mile in northeastern Pittsburgh, the Blue and Green Belts form the only concurrent segment in the system. The two belts meet (Blue northbound, Green southbound) at the northern end of the Highland Park Bridge off Exit 6 on PA 28. From there, the dual Blue/Green Belt route runs across said bridge, around the loop onto Butler Street/PA 8 South and to the intersection of Allegheny River and Washington Boulevards where the belts split up. Here, the Blue Belt continues with a right-hand turn onto Washington Boulevard/PA 8 South and the Green Belt continues straight on Allegheny River Boulevard/PA 130 East.
