The Adirondack Northway has a southern extension from the I-87/I-90 junction to US 20. This extension is a remnant from plans to run I-87 parallel to the Thruway to I-787 and is numbered as reference route 910F. It is known as Fuller Road Alternate in NYSDOT's databases. The sourthern stub with US 20 was modified to include a loop ramp from US 20 eastbound and an interchange was constructged with Crossgates Mall (the mall built the ramp to the mall; the ramp to the Northway was constructed later by the Town of Guilderland).
