Alternative B-2 is similar in alignment to B-1 with the exception of bypassing McDonald to the south and west with an interchange at Noblestown Road instead of RT. 980.
Alternative B-3 is similar to B-2 with the exception of a western route around the Quicksilver facility prior to interchanging with Noblestown Road and bypassing McDonald to the west and south.
