Project 12.5
Interstate Speed Limits

North/West Passage Project 10.6: Multistate Assessment of Interstate Speed Limit Impacts documented the history of interstate highway speed limits for the North/West Passage states. This project will continue the efforts of Project 10.6 and focus on documenting speed limit countermeasures and safety impacts by reviewing light and heavy vehicle crash data attributed to speed along the I-90/I-94 corridor.
