Alaska Highway MP 1309 Tok River Bridge Repair
Location: Tok, Alaska Client: Alaska Dept. of Transportation & Public Facilities Start Date: 2018 End Date: 2019 This project replaces an existing 250-foot-long steel truss on the Alaska Highway over the Tok River, about four miles east of Tok. The project requires a 280-foot-long x 32-foot-wide detour bridge that will be built this fall, 2018. The new permanent structure is a three span, 360-foot-long x 43-foot-wide bridge founded on 24-inch driven pipe pile at the abutments and 36-inch driven pipe pile at the piers. The bridge superstructure is a typical 54-inch deep Deck Bulb-T precast girder design. Work will start fall, 2018, shut down for the 2018-2019 winter, and start again in early spring to begin with construction of the new bridge. |

Parks Highway MP 231 Enhancements CM/GC
Location: Fairbanks, Alaska Client: Alaska Dept. of Transportation & Public Facilities Start Date: 2016 End Date: 2021 Hamilton Construction has partnered with Great Northwest Inc. as the CMGC team contracted by Alaska Dept. of Transportation and Public Facilities for this project near the Denali National Park. To enhance safety and mobility, the project includes new pedestrian facilities, a rest area, and intersection improvements. Our team will replace the Nenana River Bridge to add turn lanes, eight-foot shoulders, a multi-use path, and pedestrian underpasses at the MP 231 intersection and the north bridge abutment. We will also construct a wayside and turn lanes for the new wayside, the MP 231 intersection, and the Old Parks Highway intersection at MP 230. We are currently working with ADOT&PF on the conceptual designs and constructability as part of the preconstruction phase. Construction is expected to begin in 2018 and estimated to complete in 2021. |

Parks Hwy MP 237 Riley Creek Bridge Replacement CM/GC
Location: Denali National Park, Alaska Client: Alaska Dept. of Transportation & Public Facilities in cooperation with the Alaska Division of the Federal Highway Administration Start Date: 2013 End Date: 2016 Hamilton was prime contractor on ADOT&PF’s first Heavy Civil CM/GC contract, involving construction of a new two-span, 230-foot deck bulb-tee girder bridge over Riley Creek, realignment of the Parks Highway, heavy pile driving, cast-in-place concrete, excavation, grading, paving, and drainage. We also added left and right turn pockets, and constructed a wider bridge with increased shoulder width for pedestrian and bicycle traffic. This project was completed a full season ahead of schedule. Our team realigned the Parks Highway to upgrade a substandard curve and minimize traffic impacts during construction. Alignment grade was dropped under ARRC Bridge to allow clearance for larger loads. The project won the AGC 2015 Excellence in Construction Award. |
