Pier Covered Bridge

Newport, New Hampshire

DuBois & King was selected by the New Hampshire Division of Historic Resources (NHDHR) to provide consulting services for the historic preservation and rehabilitation of the Pier Covered Bridge. The bridge is a 217-ft-long, two-span continuous covered bridge constructed in 1907 with lattice-type trusses using Town’s double web lattice patent. Design of preservation measures and repairs included:

Installation of a dry sprinkler system
Installation of a linear heat detection system
Application of intumescent paint
Application of fire retardant
Installation of a dry hydrant
Installation of a power source for heat detection/lighting
Structural repairs to deteriorated upper lateral bracing
Repairs/replacements to timber siding
Repairs to timber deck and runner planks
Application of insecticide at abutments

Principles of the Secretary of the Interior’s Standards for Rehabilitation and the Burlington Charter were applied to all phases of the work. This project included a Section 106 historical clearance.
