As part of the I-25/Arapahoe Interchange Environmental Assesment, a
traffic study was conducted in May, 2011 to obtain baseline data
regarding existing traffic volumes and cutthrough traffic circulation
within the Walnut Hills neighborhood.
The purpose of the study
was to quantify the amount of traffic cutting through the Walnut Hills
neighborhood during peak commuting hours. A copy of the 30 page study is
available here (pdf).
