Location and Vicinity Map ___________________________________________________________________________________ Parks Highway and Big Lake Road Intersection vi Design Study Report 1.0 PROJECT DESCRIPTION 1.1 Project Location and Description The Alaska Department of Transportation and Public Facilities (DOT&PF) in cooperation with the Federal Highway Administration (FHWA) proposes to reconstruct the intersection of the Parks Highway and Big Lake Road. The proposed project is located within Section 10 and Section 12, T17N, R03W, Seward Meridian on Mat-Su Borough Tax Maps H010 and H011; Latitude 61°34’31.65” N, Longitude 149°43’27.55” W, in Houston, Alaska, within the Matanuska-Susitna Borough (MSB). The proposed reconstruction project includes reconstruction of the intersection of Big Lake Road and the Parks Highway (extending approximately 0.5 miles to the north and south of the intersection and 0.25 miles to the east of the intersection), a realignment of Little Meadow Creek to its historical flow channel, construction of a new bridge over Little Meadow Creek with a wildlife crossing, and improvement of ditches and drainage. 1.2 Existing Facilities and Land Use Parks Highway is classified as a Rural Interstate and Big Lake Road is classified as a Rural Minor Arterial, both have posted speed of 55 MPH. To the north and south of the intersection, the Parks Highway consists of two 12-foot through lanes with opposing traffic. To the west of the intersection, Big Lake Road also consists of two 12-foot through lanes with opposing traffic. Approaching the intersection from the south, the Parks Highway widens to allow a dedicated left turn lane onto Big Lake Road. Approaching the intersection from the north, the Parks Highway widens to allow a dedicated right turn lane onto Big Lake Road. Approaching the intersection from the east, Big Lake Road widens to allow a dedicated left and right turn onto the Parks Highway from a stop control. Big Lake Road and the Parks Highway were observed to have 6-foot and 8-foot shoulders, respectively, with 4:1 side slopes. Land use along the corridor consists of small commercial businesses such as NAPA Auto Parts in the northwest corner and Gorilla Fireworks in the southeast corner of the intersection; Big Lake Baptist Church on the southwest corner. Little Meadow Creek runs under and across Parks Highway just north of the intersection. The ROW is about 95-105 feet wide along Big Lake Road and 150 feet wide along Parks Highway. There is no illumination along Parks highway leading up to the intersection to Big Lake Road. However, there is illumination along Big Lake Road. 1.3 Purpose and Need The purpose of this Resurface, Restoration, and Rehabilitation (3R) project is to upgrade the intersection to: - Decrease crash rates and enhance safety; - Alleviate traffic congestion; - Accommodate future increase capacity; - Improve roadside drainage; - Provide a safe wildlife crossing to adjacent areas; _____________________________________________________________________________________ Parks Highway and Big Lake Road Intersection 1 Design Study Report - Improve mobility for vehicles and pedestrians. 2.0 DESIGN STANDARDS AND GUIDELINES Design standards and guidelines that apply to the Parks Highway and Big Lake Road Intersection are contained in the following publications: Standards: ● ADA Standards for Accessible Design, United States Department of Justice, September 15, 2010 except for the use of Detectable Warnings on Curb Ramps standards as stated in the ADA Standards for Transportation Facilities, United States Department of Transportation (U.S. DOT), 2006. ● A Policy on Geometric Design of Highways and Streets (PGDHS or “Green Book”), American Association of State Highway and Transportation Officials (AASHTO), 2001. ● Alaska Highway Preconstruction Manual (HPCM), State of Alaska,

Conclusion Appendix A: Acknowledgements Appendix B: Public Involvement Plan Appendix C: Related Studies and References George Parks Highway Scenic Byway Corridor Partnership Plan 1. INTRODUCTION The Parks Highway The George Parks Highway, usually simply called the Parks Highway, runs 323 miles from the Glenn Highway in the Matanuska Valley to Fairbanks in the Alaska Interior. Completed in 1971, the Parks Highway is one of the most important roads in Alaska. Linking the state’s two largest cities—Anchorage and Fairbanks—with spectacular natural surroundings and unparalleled recreation opportunities, this highway winds through the kind of scenery that typifies the Alaskan Interior: the continent’s highest peaks and largest glaciers, alpine tundra, taiga forests, wild rivers, and vast expanses inhabited only by wildlife. It is a common misconception that the name "Parks Highway" comes from the route's proximity to parklands. In fact, it is in honor of George Alexander Parks, governor of the Territory of Alaska from 1925 to 1933. However, the aptness of the name was recognized when it was chosen. The Parks Highway penetrates the wilderness of Interior Alaska, providing access to the region’s two largest protected areas: Denali National Park and Preserve and Denali State Park. At these two parks, travelers can indulge in myriad recreation activities during all seasons.

  • Denali for Families
    Denali for Families A Visitor’s Guide to Denali National Park and Preserve The current park lands of Denali National Park and Preserve include the traditional homelands of the Dene, also known as the Athabascan People. They are the Ahtna, Benhti Kenaga’ (Tanana), Dinak’I (Upper Kuskokwim), and Denaakk’e (Koyukon), and in the southeast park, the Dena’ina. For thousands of years, these peoples have interacted with the land to make homes, hunt and gather foods, create art, and trade. Alaska Natives have been stewards of the land since long before it was managed by the National Park Service, and they continute to practice traditional values and utilize park resources today.

  • Denali Highway Was Not Unanimous
    a study .., to determine the desirability of creating The Denali National Scenic Highway .' '" an interagency study prepared under the direction of TE 24 the Alaska Land Use Council .A4 D464 1983 N ovemher 1983 SUMMARY AND RECOMMENDATIONS SUMMARY Section 1311 of the Alaska National Interest Lands Conservation Act (ANILCA) requires that a study be completed to determine the desirability of creating a Denali National Scenic Highway System in Alaska. This report analyses a study area which includes nearly 500 miles of existing highways in Alaska and makes recommendations based on that analysis. The objectives of the study are specified in the legislation. Giving special consideration to the scenic and recreational values of the area, and to their protection, the study is to determine if it is desirable to designate a National Scenic Highway for the purposes of (1) enhancing the experience of persons traveling between national parks in southcentral Alaska; and (2) providing a symbolic and actual physical connection between those parks. The recommendations of this study pertain only to Federally-managed public lands in Alaska. The responsibility for this interagency study was assigned to the Alaska Land Use Council (ALUC). The ALUC was created under Section 1201 of ANILCA to foster cooperative land management and planning between Federal, State and other agen­ cies in Alaska. A specific function of the Council is to conduct cooperative studies. The council therefore appointed a special Study Group charged with .. overseeing this particular study . RECOMMENDATIONS 1. Parks, Richardson and Edgerton Highways - No Designation . This recommendation stems primarily from the fact that little Federal public land exists along these routes.
