Project End Result

The Alaska Department of Transportation is working with Neeser Construction to improve the Glenn Highway and Muldoon Road Interchange over the course of three construction seasons (2016 - 2018). Upon completion, the Glenn Highway and Muldoon Road Interchange will have a new diverging diamond interchange. The new interchange will have a much higher capacity for vehicles, reduce travel delays, and provide safer, more efficient pedestrian access across the highway. This project is scheduled to be complete by November 2018.
