Logged on 1st October 2008 by AndyG. Condition: Couldn't find it.
1934 Middlesex 1:10560 shows two BMs on this bridge.
On the north side one at 147.66ft which corresponds to the cancelled mark (now 2-3 bricks up above the pavement).
On the south side one at 146.90ft which corresponds to the FB.
This would probably put it below present pavement level?
As the description was 'obstructed' is it still there but buried?
