There were
two toll booths. The eastern ones were in fact between River Glade and Salisbury, and I suspect they were about
here. Google Earth low-res archival images show a blob there built when that section opens and disappearing a few years later.
As for the western one, I don't think it was at the spot indicated by
Taeolas, simply because it wouldn't be on a curved stretch. It was however somewhere between exits 258 and 280, as Longs Creek is where the MRDC section ends.
The shape of the New Maryland interchange is another interesting question. The elongated ramp was apparently built 1-2 years after the others, though I can't figure out why. A quick look on GeoNB shows parcel boundaries that could fit another WB onramp, but this was never built. The awkward intersection of those ramps seems improvised or modified after the fact, so it may have been a safety improvement once the highway was fully open. The rumour I've heard from New Maryland residents a few times is that this is due to an indigenous burial site being discovered, but that doesn't explain why this would be built afterward. A similar situation played out at the Route 2/Route 7 interchange in Oromocto, as the land acquired from the military leaves plenty of room and the correct shape for a larger, fully directional ramp from Route 2 WB to Route 7 SB.
Another curiosity is a pre-1990 planned alignment of Route 2 immediately west of Fredericton.
This seems to have been cleared before 1985 and is still visible when driving along Deerwood Drive. Is there anybody who can remember what happened here? Was there a Hatfield-era attempt at twinning Route 2? Another thing I've struggled to clarify is the previous configuration of ramps at the former Route 2(current Route 8) interchange with Hanwell Road.
