Frazer Creek Bridges

Location:

Acadia National Park
Hancock County, Maine

CE Category

23 CFR 771.117(c)(28): Bridge rehabilitation,
reconstruction, or replacement or the construction

See 23 CFR 771.117 for full description of CE categories, including additional requirements when applying (c)26-28.

Project Description
The project includes rehabilitation of three bridges to extend the serviceable life of the structures. Structure 1700-010P Paradise Hill Bridge crosses over Duck Brook Road, which is a paved carriage road that is used by cyclists and hikers. Structure 1700-020P Maine Route 233 Bridge carries Paradise Hill Road over Maine Route 233 and is situated between two stone cliffs. Structure 025P Frazer Creek Bridge carries Schoodic Loop Road over Frazer Creek. At Paradise Hill Bridge and Maine Route 233 Bridge, proposed work includes installation of a waterproof membrane inside the bridges, which requires removing the road surface, removing all fill material from inside the bridge, placing the membrane, returning clean fill, and reestablishing the road surface. In addition, the project includes cleaning and removing debris from weepholes and inlets, removing efflorescence, and cleaning and sealing joints, and repointing select mortar joints. Minor vegetation clearing may be needed around the structures to allow the installation of temporary scaffolding. At Frazer Creek Bridge, proposed work includes concrete repair, cleaning and sealing joints, and repair work done to the post tensioning grout pockets. There will be no inwater work associated with this structure repair. A debris shield will be placed beneath the bridge to prevent any debris or material from entering Frazer Creek during construction. Object markers and signs may be installed or replaced at the structures. Temporary detours on existing roads will be used during construction at all bridges. No significant ground disturbance will occur as a result of the proposed project.
