Glenn Highway and Muldoon Road Interchange Improvements

The Alaska Department of Transportation and Public Facilities (DOT&PF) has determined that the Glenn Highway/Muldoon Road interchange needs to be upgraded to accommodate current and future needs. The purpose of the project is to increase safety and circulation for both cars and non-motorized traffic and to make it easier for freight trucks to travel through the interchange. The goal is to develop and implement a long term solution to address vehicle and pedestrian traffic concerns within the interchange area.
The Muldoon Road/Glenn Highway interchange is the gateway to Anchorage. It is the northernmost junction between the Glenn Highway and Anchorage’s arterial street network and it is the primary access to the Tudor/Muldoon road corridor. Constructed in the mid-1970s, the interchange is a rural, partial cloverleaf design.
Overall, land development in the north Muldoon area has caused significant traffic volume increases. Sidewalks and non-motorized trails are limited to the east side of the interchange and they often force pedestrians and bikers to travel out-of-direction to get across the interchange. As a result, some pedestrians cross at undesignated locations creating unsafe conditions. Additionally, bridge clearance for trucks and large vehicles is below current minimum height standards.
DOT&PF and its consultant, DOWL HKM, have begun the Glenn Highway and Muldoon Road Interchange Improvements project and will be performing preliminary scoping efforts that will identify alternatives that may move forward into future environmental documentation, design, and construction phases. Elements of this project include public and agency scoping, preliminary environmental and engineering services, a noise analysis, and traffic capacity and safety analyses.
Preliminary scoping and engineering is anticipated to conclude in October 2013. Public involvement activities will continue throughout the project.
This project is currently state funded, however to maintain eligibility for use of federal funds, all scoping activities will be conducted in accordance with the requirements of the National Environmental Policy Act (NEPA).
