Randall Covered Bridge

Lyndon, Vermont

Selected by the Town of Lyndon to provide professional engineering services to conduct investigations and develop plans and cost estimates for the restoration and repair of the Randall Covered Bridge. The bridge, constructed in 1865, is a 68-ft-long, single span structure that spans the East Branch of the Passumpsic River. The bridge is 14 ft, 8 inches wide overall and utilizes Queen Post trusses spaced 13 ft apart to support the deck and roof. Recommendations for repairs:

Replace loose, broken, rotted, or warped siding
Replace decayed deck with lighter, traditional plank deck
Application of insecticide for powder post beetles/carpenter ants
Replace metal roof
Replace worn running boards and broken roof rafters
Replace rotten truss members
Replace missing mortise/tenon knee brace connections
Reconstruct rotten truss joints
Repair deteriorated concrete abutments
Apply fire retardant on exposed timber
Replace worn/decayed siding

Principles of the Secretary of the Interior’s Standards for Rehabilitation and the Burlington Charter were applied to all phases of the work.
