Steve:
The answer depends on the signal bridge. Most of the signal bridges installed
from 1913 on were built with about 24' clearance. Some of the earliest
"lattice" truss or "triangular" truss signal bridges that were installed west
of Chicago had 22' clearance. Most of these were relocated in subsequent
years, and typically were reinstalled with new towers or raised on pedestals to
bring their clearance to 24'. If you want further detail on a particular
bridge, let me know.

Hi,
Can anyone tell me what the suggested or minimum clearance was for CB&Q signal
bridges?
Thanks.
