As Alaska’s cities and communities grow, so does the demand for safe, reliable non-motorized infrastructure, including sidewalks, bike lanes and multi-use trails. These facilities support transportation, recreation and public health, offering residents and visitors a way to commute, exercise and explore Alaska’s unique landscapes. In urban centers like Anchorage, Fairbanks and Juneau, pedestrian and bicycle commuting has increased significantly, with Anchorage seeing a 75% rise in bike commuters since 2000. Non-motorized infrastructure also plays a key role in reducing traffic congestion, improving air quality and lowering public health costs, as physical inactivity is linked to $117 billion annually in U.S. healthcare expenses. Additionally, Alaska’s 5,000+ miles of trails serve as major tourism and recreation assets, drawing outdoor enthusiasts year-round.
Despite these benefits, expanding and maintaining non-motorized facilities in Alaska presents unique challenges. Harsh winter conditions and freeze-thaw cycles make year-round usability difficult. Steep terrain, permafrost and gaps in connectivity further complicate infrastructure development, particularly in remote areas. Funding limitations also hinder progress, as communities struggle to secure resources for long-term maintenance. To overcome these barriers, engineers and planners must implement innovative, climate-resilient solutions — from durable materials and smart design strategies to policy shifts that prioritize active transportation. This article explores the key challenges, constraints and engineering strategies needed to enhance Alaska’s non-motorized transportation network.
Challenges and Constraints
Designing non-motorized infrastructure in Alaska presents unique challenges shaped by location, climate and local design criteria. In urban areas, the focus is on connectivity, safety and multimodal integration, while rural communities face funding limitations, rugged terrain and right-of-way constraints. However, many obstacles, such as harsh weather, high maintenance costs and network gaps, affect both urban and rural settings, requiring adaptable and resilient solutions.
Harsh Climate and Extreme Weather Conditions: Alaska’s severe winters bring heavy snowfall, freezing temperatures and extended darkness, making year-round non-motorized travel difficult. Freeze-thaw cycles create icy surfaces, compromising safety, while snow accumulation obstructs sidewalks, bike lanes and trails. Urban areas require well-lit, well-maintained pathways, while rural communities — where maintenance resources are scarce — need sustainable, low-maintenance solutions.
Funding and Budgetary Constraints: Non-motorized infrastructure faces high construction and maintenance costs due to harsh weather, specialized materials and short building seasons. Many communities depend on federal grants and funding programs, which often come with strict design requirements that may not align with local needs. Long-term maintenance remains a challenge, especially in rural areas.
Safety and User Accessibility: Conflicts between motorized and non-motorized users are a major concern, particularly along high-speed highways and busy urban streets. Poor lighting, reduced visibility, and icy conditions further compromise safety. Ensuring ADA compliance is essential for equitable access, but public opinion on non-motorized facilities varies, with some communities resistant due to cost or property concerns.
Connectivity and Land Use Barriers: Fragmented pedestrian and bike networks make connectivity a challenge, especially in urban areas with right-of-way limitations and existing infrastructure constraints. In rural areas, long distances and lack of dedicated facilities force non-motorized users to share roadways with high-speed traffic. Integrating these facilities with public transit and roadway networks is critical.
Geographic and Terrain Limitations: Alaska’s steep mountain slopes, unstable soils, and permafrost present significant design and maintenance challenges. River crossings, wetlands and remote locations require innovative solutions such as elevated boardwalks or reinforced embankments to minimize environmental impact while ensuring durability. Private land ownership and right-of-way acquisition also complicate project development.
Solutions and Best Practices
Addressing these challenges requires innovative, adaptable and context-sensitive solutions. Successful projects must balance durability, safety and connectivity while meeting the needs of both urban and rural communities.
M&O Considerations for Design Strategies: To ensure long-term functionality, design strategies prioritize durability and low maintenance. Weather-resistant materials, improved drainage and snow/wind mitigation features reduce maintenance demands while enhancing safety. The Kodiak ADA Improvements project, for example, installed a new ADA-compliant ramp (covered) at a middle school, eliminating the need for frequent snow shoveling. In the Chugach Foothills, boardwalks were constructed wide enough for maintenance vehicles, allowing for easier snow removal and upkeep. Flexible pavement surfaces help minimize cracking, and the Seward Highway MP 100-105 project implemented permeable ditches and culverts to improve drainage. By integrating these M&O-conscious design solutions, Alaska’s non-motorized facilities can remain safer, more accessible and cost-effective throughout the year.
Funding and Policy Innovations: Expanding and maintaining non-motorized infrastructure requires creative funding strategies and policy shifts. Advocating for state and federal funding, such as Bipartisan Infrastructure Law grants, is essential. Public-private partnerships can support infrastructure development. Additionally, incorporating non-motorized facilities by default in all transportation projects ensures growing demand is met. Project funding also dictates design standards—starting with required guidelines based on funding sources helps determine feasibility before exploring variances or exceptions. Projects like the W. Dimond Boulevard Upgrade required coordination between the Municipality of Anchorage (MOA) and Alaska Department of Transportation & Public Facilities (DOT&PF) standards, while the Campbell Creek Trail Crossing project is federally-funded with local oversight. By aligning funding strategies with policy-driven design requirements, Alaska can create a more connected, accessible and well-funded non-motorized network.
Improving Connectivity and Community Engagement: Creating a well-connected network requires seamless integration between trails, bike lanes and transit hubs. Every trail should serve a purpose, connecting users to schools, parks or business districts. Community engagement helps ensure usability and public support. Adaptive reuse of existing infrastructure is another effective strategy, such as the Sterling Highway MP 45-60 (Cooper Landing Bypass) project, which envisions repurposing portions of the old highway into a future pathway The Fairview Loop Road Rehabilitation improved pedestrian access, while the Chugach Foothills Trail Connector and Seward Highway MP 100-105 projects expanded networks for greater accessibility. By prioritizing connectivity, thoughtful planning and community input, Alaska can develop a more accessible and interconnected non-motorized system that serves residents for years to come.
Enhancing Safety and Accessibility: Traffic-calming measures, strategic design choices and universal accessibility principles are crucial for safety. Separated bike lanes and pedestrian pathways protect users from high-speed traffic. Enhanced wayfinding signage and lighting improve visibility, especially in winter. Projects such as Fairview Loop Road Rehabilitation, 120th Avenue Upgrade and Airport Way West Improvements transitioned users from road shoulders to dedicated pathways, significantly improving pedestrian safety. Emergency access considerations, particularly for rural trails also ensure response capabilities in remote areas. By integrating universal design, clear wayfinding and infrastructure that prioritizes user protection, Alaska can create safer, more inclusive and more functional non-motorized networks.
Smart Planning and Engineering Approaches: Effective infrastructure begins with data-driven planning. GIS mapping and analysis help identify constraints like utilities, right-of-way limitations and challenging terrain, allowing planners and engineers to select optimal routes. Designing multi-use corridors that accommodate a variety of users—pedestrians, cyclists and even skate-skiers—enhances functionality and accessibility, as seen in the Alaska Long Trail project. Context-sensitive solutions consider different urban and rural needs, such as shifting the roadway on Airport Way to provide continuous pathways for residents. By prioritizing data-driven decision-making, multi-use functionality and adaptable design solutions, Alaska can develop efficient, well-integrated non-motorized infrastructure that meets the diverse needs of its communities.
Conclusion
The future of non-motorized transportation in Alaska depends on continued investment, planning and incremental development. Expanding the network will not happen all at once; instead, it requires a long-term commitment to adding new pathways one section at a time. By prioritizing durable designs, innovative funding and integrated connectivity, Alaska can build a resilient and accessible non-motorized network that serves its residents and visitors for generations to come. Each new project brings the state closer to a fully connected system, ensuring that walking, biking and other forms of active transportation remain viable, safe and sustainable options throughout Alaska.
