Below you will find all of the available Data Needs Analysis Studies (DNAs). DNAs
are brief, limited, small scale studies used to gather basic existing
data; to identify potential project development concerns; and to better
define the project purpose, need, and scope. The DNAs
provide basic planning-level information on all smaller projects, such
as bridge replacements or intersection realignments, that do not require
lengthy, detailed planning studies.
