Parks Highway MP 237 Riley Creek Bridge Replacement
Federal Project No. IM-BR-0A4-4(19), State of Alaska Project No. 63763
The Alaska Department of Transportation and Public Facilities (ADOT&PF), in cooperation with the Alaska Division of the Federal Highway Administration (FHWA), is proposing to replace the Riley Creek Bridge near milepost (MP) 237 of the Parks Highway. In addition to the proposed bridge replacement, the project includes the following:
- Addition of a left turn pocket from the Parks Highway onto Park Road;
- Realignment of the Parks Highway at this location to upgrade a sub-standard curve at the northern project limits and minimize traffic impacts during construction;
- Minor realignment of adjacent bicycle and pedestrian path to improve intersection geometry;
- Addition of a right turn pocket on Park Road to reduce delay for motorists turning onto the Parks Highway;
- Widening the proposed bridge to accommodate the left turn lane to access Park Road and 8-ft shoulders for pedestrians and bicyclists; and,
- Minor grade adjustment under the Alaska Railroad overpass at the southern end of the project to provide additional vertical clearance for vehicles on the Parks Highway.
To develop the design with greater innovation and plan the construction to find efficiencies and cost savings, the Department applied for and received permission from the Federal Highway Administration (FHWA) to use an alternative procurement method called Construction Manager/General Contractor (CMCG). Please see "CMGC Information" link for additional information on this procurement method.
