Revisions to Brooklyn Bridge

After some time spent doing "knuckles" and train stuff, and preparing for solo guitar work, back to the Bridge.
David McCullough's book specifies the size of each tower at top (276'6" level) to be 136x53.
My work is done at 135'10.5"x 59'. Not sure how I arrived at those numbers,(ed. I got 135'10.5" from Roebling's original drawings) but I'm willing to take David at his word.
(ed.No idea where 59' came from....52'10.5" is on Roebling's drawings.. )
There appear to be some basic differences between Roebling's original and the executed plan.
For instance, Roebling differentiates between the NY and Brooklyn towers in basic dimensions, but McCullough's stats say they are the same.

I'm inclined to leave level 261 3 thru 273 3 alone for now. A lot went into them and they look good.

Perhaps its time to review the whole drawing (since its been done in fits and starts for the last couple of months) and get some definite numbers for each level and see what elements in the drawing are either mistakes or nonessential......


z_Level 270 3 actual
 shows the diagonals from 261 3 to 270 3. At 270 3 there is an overhang and the overhang is denoted by
z_Level 270 3
April 19 temp
shows how I took the dimensions from level 141 6 and basically copied them to 270 3 for the overhang dimensions

z_Base to 12 ft
is just what it says.....level 0' to 12'
z_Level 1 renamed z_Level 19'6 to 59'6
is 19'6" to 59'6"
z_Level 2
is 67' to 103' 6"
z_Level 3 renamed z_Level 114'
is a flat plane at 114'
z_Level 4 renamed z_Level 114' to 116'
is 114' to 116'

Looks like a left out a lot of stuff on or about the roadway level......Then started meshing again using, maybe, the peaks of the arches for reference....Who knows....
That's what happens when you are your own project manager and the work is somewhat unorganized.


In the weeds!

The roadway should start at 120'4", according to my numbers.
The numbers in McCulloughs book just don't add up.....

"Height of roadway at towers 119'
Height of arches above roadway 117'
Height of towers above roadway 159'"

They just don't work....

Height of arches above roadway 117', appears to agree with other sources.....
