However, with an estimated cost of more than $30 million, project
funding was a significant hurdle. Region Nine Development
Commission and the National Association of Developmental
Organizations (NADO) approached MnDOT about pursuing
Disaster Relief Funds from the Economic Development Administration (EDA). These groups collaborated and secured $9 million for
the project, making Highway 169 the first roadway in the nation to
be funded with EDA Disaster Relief Funds.
This four-lane divided roadway project was not easy. The
improvements included replacing seven miles of concrete pavement,
reconstructing and raising the grade of two miles (up to six feet
in some areas), improving drainage, and adding median barriers

to minimize head-on crashes-all within right-of-way restricted
by the Minnesota River floodplain and nearby bluffs. In addition,
because of the high traffic volume, it was imperative that closures
and detour durations were minimized. Innovation was crucial to
meet all of these stipulations.
Bolton & Menk, Inc. used the 3D modeling software Corridor
Modeler by Bentley to develop 3D surfaces for all sections of the
roadway. We were able to reach a level of accuracy not typically
achieved with traditional alignments, profiles, and cross sections.
The design team also analyzed the design through innovative 3D
visualizations. Examples include a 3D analysis of the stopping sight
distance around a proposed median concrete barrier on a superel-
