The majority of the bridges in the US were originally constructed before GPI was founded. Today, many of these bridges have either exceeded their life span or are rapidly deteriorating. Our bridge expertise includes NBIS inspection, rating, and design. Our designs include both replacement and rehabilitation, and have involved utilizing some of the industry’s cutting edge solutions such as composite decks, precast bridge units for accelerated construction, and carbon fiber tubes (aka Bridge in a Backpack). Several of our bridge designs have won awards including the national ACEC Project of the Year. Our work with the Federal Highway Administration as support for the Bridge Preservation Expert Task Group has acknowledged GPI as a national leader in Bridge Preservation.

Old Blenheim Bridge Replacement
Client/Owner: Town of Blenheim, Schoharie County, NY
Location: Blenheim, Schoharie County, NY
GPI Contact: Edmund Snyder III, PE
Description: GPI provided professional design services for the replacement of the approximately 210-ft clear-span Blenheim Covered Bridge, services include preliminary and final design services to construct a replica structure that included conceptual drawings, initial cost estimates, site investigations including abutment inspections, regulatory compliance, alternative investigations, and environmental compliance. Once an alternative was selected, GPI with assistance from Hoyle Tanner provided preliminary and final design services that included preparation of design plans, specifications and construction cost estimate.
The Old Blenheim Bridge was a wooden covered bridge that spanned the Schoharie Creek. Nichols Montgomery Powers was brought in from Vermont to build the bridge by a group of local businessmen who formed the Blenheim Bridge Company for the purpose of constructing this bridge. The bridge opened in 1855 and remained in use for vehicles until 1931. In the spring of 1869, a severe freshet washed out a wide channel across the western approach. A wooden extension was added to the Blenheim Bridge to span the new channel. In 1895, it was replaced by an iron extension. The wooden covered bridge was retired from use in 1931 and the Board of Supervisors voted to retain the bridge as a public historical relic. The Old Blenheim Bridge was destroyed by the events following Hurricane Irene on August 28, 2011. During this storm, the bridge superstructure washed away. The abutment and pier were left remaining in their original location. Various components from the original bridge were recovered after the storm and stored in a field behind the Mattice Family Barn along Route 30A approximately 1 mile north (downstream) of the former bridge location. The bridge was listed by the U.S. Department of Interior, National Park Service, as a National Landmark in 1964 and a National Historic Civil Engineering Landmark in 1984. The National Historic Designation was requested to be removed by NYSHPO on September 8, 2014. Up until its destruction, the bridge remained as the world’s longest single span, covered wooden bridge still in existence.
It includes construction of new concrete abutments with formlined and stained concrete surfaces(to mimic the original stone abutments), surrounded by heavy stone fill. The abutments sit on steel H-Piles and soldier pile and lagging walls were used during construction to retain the embankment. Replica with trusses, counter diagonals, cross beams, interior arches, stained batten boards siding, deck planks, roof rafters, vertical arch members, timber deck, and floor beams were used. New hardware included galvanized timber bolts. In addition, project include a pedestrian connection with timber railing, concrete walkway and pavers from the bridge to the existing roadway. Construction was completed in 2018 and GPI provided construction support and inspection services that includes a full time Resident Engineer.

American Falls Bridges
Client/Owner: NYSDOT
Location: Niagara Falls, NY
GPI Contact: Thomas Bender, PE
Description: GPI is performing Phases I-IV (Preliminary Engineering) for the rehabilitation / replacement of the American Falls Bridges. Located in the historic Niagara Falls State Park within 1000 ft. of the brink of Niagara Falls, these two bridges connect the Mainland USA to Goat Island via Green Island and provide a direct linkage within the Park for trolley transport of nearly 8 million visitors per year to and from Goat Island. Both structures are 3-span Thatcher Concrete Arch Bridges (an early form of a filled reinforced concrete arch) faced with stone masonry that had deteriorated to the point that necessitated a temporarily closure in 2004. To maintain this critical linkage within the park, a temporary truss structure was installed over the arch structures, a short-term fix until a long-term solution was developed. In addition to eliminating structural deficiencies, restoring trolley service to the island and maintaining the historic character of the bridges, a key project objective is to improve accessibility to meet current ADA requirements.
