Estimated costs of new managed lanes based on existing right-of-way and lane configuration, geography, and presence of roadway connections.
Minneapolis, Minnesota, United States
Summary
Mn/DOT began operation of the State's first application of HOT lanes on a segment of the Interstate 394 (I-394) corridor in the Minneapolis/St. Paul region on May 16, 2005. This system is one of the first in the United States that dynamically adjusts pricing levels in response to traffic conditions. Recognizing the use of the I-394 MnPass deployment as a test bed for evaluating the viability of the HOT lane concept and the broad interest in the application, Mn/DOT implemented a comprehensive evaluation effort to assess the system.
