Indeed, the new bridge makes photography difficult. An interesting opportunity might be available now with the new phone mast in West Bessacarr - it means a lane has been opened up parallel to the SYJR line to the point where the SYJR crosses the ECML, so you can get quite near to the ECML. I don't know if this is permanent though, it might just be for the duration of the works. There's also opportunities for some good photos on the relief line if you know where to go through the woods at the bottom of West Bessacarr which includes some old Dearne Valley embankments which are now part of the nature reserve - but you have to know where you're going because there are some very steep drops and marshes in places.
