de Blaquiere bridge

This says it’s a bridge over the canal at the North Circular Road. The existing canal doesn’t cross NCR, however. Maybe, it’s the filled in bridge at Phibsboro that crosses the old spur, leading into Blessington Basin.

the place on the n.c.r by the library library, the monument to some dead soldier is there, leads onto the long park that goes perpendicular to the n.c.r, down behind the old ice rink that is now tragically a carpet shop.

the long park used to be the canal and led down almost as far as the kings inn. the n.c.r used to have a humpback bridge over the canal to allow for boats to travel under, which has since been destroyed to level the road.

It actually went a bit further. The canal crossed the road by an aquaduct and ran in front of Broadstone Station where the terminus was. Further details of this on:
