I would like to thank the following
people for assisting me with my research and making this
report a reality: Victor Tsai and Dean Van Landuyt at the
Texas Department of Transportation, who provided me with
information about the design of Texas highways; John Bray
at the Minnesota Department of Transportation and Kent
Worley, who provided me with a wealth of information
regarding the Duluth I-35 project; Sara Stein of the
Portland design firm McKeever/Morris, Inc., who provided
me with information about the proposed I-405 cap in
downtown Portland; and Tom Colbert at the University of
Houston Gerald D. Hines College of Architecture. I also
want to thank Lucy Buck at the Downtown Austin Alliance
for her suggestions and support and Bruce Webb at the
University of Houston Gerald D. Hines College of
Architecture for his insights and input. A special thanks
goes to Susan Handy and Sinclair Black, my readers at the
University of Texas School of Architecture, for their
invaluable guidance. Finally, I want to thank my fiancee,
Lori, who spent endless hours driving me around city
freeways so I could take photographs and provided
much-needed computer support. Without her, this report
would have been difficult, if not impossible, to
complete.
