Robert Davinroy, P.E. Principal Consultant CDG Engineers USA Chief, River Engineering, U.S. Army Corps of Engineers St. Louis, Missouri USA
Challenges for
Navigation
Development on the
Magdalena
Overcome by Lessons
from The Mississippi
1 tow = 1800 trucks
35,000 trucks per day off the road
in St. Louis region
12,775,000 Trucks off the Highway at St. Louis Per
Year!!
Barge Navigation:
The most efficient, economic,
environmentally efficient mode of
transportation on the planet!
Inland waterways allow tremendous savings in fuel consumption, reduced greenhouse gas emissions and air pollution, reduced traffic congestion, fewer accidents on railways and highways, and less noise and disruption in cities and towns.
