The former Troy & Schenectady line was still operating when the Northway (I-87) was built (1960’s) and there still was a grade crossing on the Northway a short distance south of the “Twin Bridges” over the Mohawk River (this was probably one of only a very few grade crossings on an Interstate Highway in the United States). It wasn’t there long, as the line was cut back within a couple of years to an industrial site just east of Route 9. You can still see where the line passed under Route 9 perhaps a mile north of Boght Corners.
During the period that the line crossed Interstate 87 (ETT has a typo “89”) at Dunsbach Ferry, the following instruction appeared in the Employee Time Table under “special instruction 103 public crossings at grade: Manually controlled traffic signals:” “Trains or engine must stop in rear of stop sign and a member of crew must operate pushbuttons in manual control box. After traffic signals have been operating for at least twenty seconds train or engine may proceed over crossing, signals must be restored to normal position after movement over highway has been completed.”

UPDATE in 2012:
Railroad and trolley historian and author Gino DiCarlo has done some research and actually found pictures of this crossing.
See his article on “CROSSING THE NORTHWAY”
Update June 3, 2012 from Gordon Davids:
The T&S Branch highway grade crossing was in place and active on opening day of I-87 in 1959. Traffic signals hung over the highway, and cross bucks were on each side of the road.
The state engineers told us at the time that the railroad was up for abandonment, and the state wasn’t about to spend the money necessary for a grade separation. They got a waiver from the Public Roads Administration (pre-FHWA) to permit the crossing for a limited period. I think they had to extend the waiver a few times.
I looked on Google maps street view today, and saw an aluminum pole alongside the northbound highway and an aluminum instrument case still in place just south of it. I’m sure that they were part of the highway signal system that protected the crossing.
