Trunk Highway 56

Minnesota | Transportation

Overview

ISG led a project to accommodate development of a new $25 million grain handling facility project in rural Minnesota that the firm also designed.


Opportunity

With a new grain handling facility nearby, TH 56 needed to implement turn lanes to make a key intersection safer and more convenient.

Solution

ISG performed and coordinated all work associated with an intersection control evaluation (ICE) for the project, which was reviewed by the MnDOT Metro District. Given that the ICE report showed the existing intersection layout resulted in an unsafe and inefficient condition, ISG proposed and evaluated an option to construct a left turn lane in the place of the existing bypass lane. Based on the evidence outlined in the ICE report and alternate design ISG proposed, Dakota County and MnDOT approved moving forward with a reconfiguration of the existing intersection. The design promoted efficiency of traffic traveling on the TH 56 corridor and increased the safety of the intersection.

ISG prepared the subsequent design and construction documents and coordinated approval of the project by multiple agencies including MnDOT. This also included preparation of a project memorandum and environmental review documents, specifications and special conditions, hydraulics, a traffic study, survey, permitting, and coordination with utility companies, the adjacent railroad, and neighbors.
