Missouri D.O.T. I-70 North Bride
Enhancements – St. Louis, MO
Driven by this St. Louis community’s
desire for both an aesthetic and
durable
design,
the
Missouri
Department of Transportation selected
a duplex system, custom fence panel
for ten bridges in this urban area. With
exposure to a wide temperature range,
high humidity, and road salts, only
hot-dip galvanized steel tube, angle,
and mesh would provide the long-
term, maintenance-free performance
required. Painting over the zinc coating
delivered an appearance consistent
with the surrounding community.
Brite Zinc was used at welded joints and for
touch-up, to give superior protection
against the corrosion within the duplex
system.
