Research Pays Off Webinar Series

Every 3rd Tuesday of the month, 10 a.m.

The National Road Research Alliance will provide a monthly seminar* to highlight research topics that will make an impact on the work done here in the state of Minnesota and around the country.

We send out a formal invitation and presentation announcement prior to the webinar through the NRRA email list. Make sure you're signed up to receive these and other occasional announcements.

We want to hear from you!

If you have a project or topic you'd like to share with our viewers, please contact Lauren Dao at lauren.dao@state.mn.us.
