Safety and Mobility Interchange Program

Traffic on a highway

Highway interchange construction project grants


The purpose of the 2011 Safety and Mobility Interchange Program was to provide funding for “…construction of interchanges involving a trunk highway…” that “…relieve growing traffic congestion, and promote traffic safety…” as appropriated in Minnesota Laws 2010 Chapter 388, Section 2. $30 million of the Chapter 388, Section 2 appropriation was distributed through the Transportation Economic Development Program, a joint effort of the Minnesota Department of Employment and Economic Development and the Minnesota Department of Transportation. Applicants were required to provide the information requested in the SaM Interchange Program solicitation:

The required KA crash and approach traffic volume data came from the 2009 crash data toolkit. Applications for the program were accepted from MnDOT districts only. MnDOT received 15 applications requesting $153 million for the $44.5 million in available funds.


As a result of the program, $44.5 million in grants towards the construction of highway interchange projects promoted safety and reduced congestion at four dangerous intersections in Greater Minnesota and the Twin Cities metro area. The grants were funded through a bond appropriation made by the 2010 Legislature and designated specifically for interchanges, and enabled these four projects to be constructed earlier than they otherwise would have been, reducing both crashes and congestion sooner:

These projects replaced existing signalized intersections with interchanges and ramps. Each of these projects has funds from other sources committed to them as well. The total value of the construction on these four projects exceeds $70 million.
