- Old North Branch Road over North Branch River, Antrim, NH – Design, permitting, and construction administration for replacement of a critically deficient steel, 26-foot wide by 44-foot span, I-beam bridge with a corrugated steel and concrete deck founded on abutments constructed of dry laid cut stone and rubble masonry. The replacement structure is a 30-foot wide by 80-foot span steel plate girder bridge, founded on cast-in-place concrete abutments. The bridge was lengthened to relocate the abutments outside of the main channel of the river, thereby reducing stream velocity and improving the hydraulic capacity at the bridge.
- High Haith Road over Squam Lake, Center Harbor, NH – Design, permitting and construction administration for the replacement of a narrow concrete slab deck, founded on stone masonry abutments. The bridge was posted for 6 tons and was on the NHDOT’s Municipal Redlist due to severe deterioration of the bridge deck and settlement of the stone abutments. The replacement structure is a 24-foot span precast concrete voided slab bridge, founded on cast-in-place concrete abutments. This bridge is the only means of access for residents on the island and the Town Beach. A temporary detour road allowed access to the island during construction.
- Depot Street Bridge over Contoocook River, Antrim & Bennington, NH – Design of Phase I Rehabilitation to provide guardrail safety improvements, as well as some joint repairs to prevent further deterioration until the bridge can be studied for rehabilitation or full replacement in Phase II. The bridge was constructed in 1946 and is a narrow steel beam structure with a cast-in-place reinforced concrete deck with severely deteriorated w-beam guardrail on each side. The bridge spans approximately 70 feet, and is 16 feet wide curb-to-curb, with an approximate 20-foot overall width. The abutments are constructed of dry laid stone masonry from a previous bridge, with a cast-in-place concrete cap for bearing seats. Phase II will evaluate options for rehabilitation or replacement.
- Water Street over Great Brook, Antrim, NH – Design and construction administration of an emergency bridge replacement. The existing corrugated metal pipe (CMP) spans approximately 10 feet and was closed due to excessive corrosion and rust through. The pipe is severely undersized and suffered damage during recent floods. A fast track design was implemented for a 20-foot rigid frame founded on spread footing with stem walls. Provisions to accommodate an existing sewer line were incorporated into the wingwall foundations.
- Old Marlborough Road over Charcoal Brook, Dublin, NH – Design, permitting, and construction administration of an emergency bridge replacement.
