TH-15 is a four-lane arterial through the cities of Saint Cloud and Waite Park, with a posted speed limit of 45 mph. Average daily traffic (ADT) within the study area ranges from 31,000 to 36,500 (2017), which is nearing daily capacity for a facility of its type. It is also a major freight corridor, carrying between 1,500 and 1,750 heavy commercial vehicles each day.
APO performance measures indicate that the intersections at 2nd Street South and Division Street are among the worst in the region in terms of travel time reliability.
A critical crash rate analysis by APO staff shows that the intersection at 2nd Street South exceeds 2.0. Three other intersections – Division Street, 3rd Street North, and 12th Street North – are between 1.50 and 1.99.
Given the volume and speed of traffic carried on the corridor and the width of the right-of-way, TH-15 is somewhat of a barrier to good east-west traffic flow, particularly for non-motorized travel modes.
During the development of the most recent Metropolitan Transportation Plan, the APO heard a number of dissatisfied comments from the general public about how TH-15 currently operates. Traffic modeling indicates that operations will get worse as the urban area grows, with ADT increasing as high as 51,000 on some segments.
The members of the APO desire to improve operations on TH-15 to increase safety, mobility, and improve traffic flow, both now and in the future.

What Is Happening Now?
Feb. 14, 2020
The evaluation committee for this study met and reviewed all four proposals received as part of our request-for-proposals process. They ranked the proposals in priority order. We are currently negotiating with the top ranked firm to finalize the scope-of-work and cost for the study.
A consulting firm will be put under contract to complete this planning study on or before Dec. 31, 2020. The exact process of the study is unknown at this time – that will come to us in the winning proposal. However, given the volume of traffic that uses TH-15 and the importance of the corridor to regional traffic flow, we do know there will be a robust public-input campaign to solicit public comments.
How Can You Participate?
As formal public input events and opportunities are scheduled, we will update this page. You can also monitor the APO’s Facebook page or sign up for our “Interested Persons” mailing list to be notified of public input opportunities. Go to our GET INVOLVED page and use the SIGN UP TO STAY INFORMED form at the bottom of the page.
