I think there might be a feasible fix for your London area (only terrain).
Includes a new "terrain.cfg" file.

File name via "avsim" - "fsx_modified_terrain_cfg.zip"

Check it out, it might solve some issues with terrain, not including though bridges.  

BTW it's also, currently being uploaded to SimV.

Well I'm glad it works somewhat, I believe the patch for FSX from M$ should include something of a similar terrain fix other then terrain, and for bridges, I'll let you know If I come by anything!.
