them informed of the bridge and its
progress, a live webcam was used.
The use of the eSPAN140 software
for bridge design was unique to this
project. Using this tool meant the
county didn't have to wait for an
engineering firm to produce various
designs. After successfully erecting the
Jesup Bridge using this tool, county
engineers can now be confident in
designing a bridge to their specific
needs and then being able to share it
with others, even though a rendering
may not be complete. Additionally,
based upon geographic location, the
software is programmed to consider
typical production and stocking pat-
terns of local steel mills and service
centers to ensure material availability.
