PEDESTRIAN BRIDGE

Hudson River Way Pedestrian Bridge CHA designed a 650-foot long by 24-foot wide, five span pedestrian bridge over I-787 and CP Rail and create a redevelopment plan for an adjoining waterfront park under the “Pass-Thru” program. The bridge has four continuous spans of haunched girders (girder depth varies from 4 to 8 feet) including the main span of 197 feet (spanning six interstate route lanes and two CP Rail tracks). The fifth span connects to a grand staircase on the western approach to the bridge. The bridge also has an elevator with three stops, a connection to the second level of an existing parking garage, spans over countless utilities, had archaeological remains found during substructure excavation, engraved brick pavers embedded in the walkway surface, ornamental steel bridge railing, precast concrete obelisks supporting light fixtures, ornamental “Texas” concrete barrier, ornamental steel flag poles on architectural concrete towers, and a two span, 85-foot long prestressed concrete handicapped access ramp.

The bridge and park work together as a virtual outdoor museum of Albany history. Several prominent design features — nautical-looking banners, flagpoles, and a custom granite compass inlay on the promenade— reference the City’s beginnings as a shipping community. Urban design elements such as black iron fencing and period lighting fixtures help reinforce a historical theme.

Accommodating the City’s requests for these aesthetic features, yet maintaining the project budget and satisfying all federal and state environmental and design requirements, often required creative solutions from the design team. For example, cast-in-place concrete textured by form liners, rather than more expensive stone facing, were used to create aesthetically pleasing bridge facings as requested by the client.

PEDESTRIAN BRIDGE

Blakely Road Over I-89 As part of our General Services Term Agreement with the Vermont Agency of Transportation, CHA was responsible for Type Studies through Final Design of a separate pedestrian bridge on Blakely Road over I-89 in the Town of Colchester, VT. The bridge structure is a two-span (125 & 140 foot) pony truss with a six-foot walkway designed for pedestrian, snow and snow removal vehicle loadings. Approaches to the bridge were built on widened embankments which utilize precast concrete blocks as retaining walls in areas of high fills.

PEDESTRIAN BRIDGE

Rogers Bridge over the Chattahoochee River The Rogers Bridge project will provide the missing bicycle and pedestrian link between the Cities of Duluth and Johns Creek by replacing the 110-year old bridge across the Chattahoochee River to Rogers Bridge Park in Duluth and the future Cauley Creek Park in Johns Creek. This bridge will also allow greater access to public spaces and parkland along the river, access to the Western Gwinnett Bikeway, and bicycle and pedestrian connectivity to Fulton and Gwinnett Counties and surrounding communities.

The project will replace the existing 320-foot bridge (that includes a 228foot main truss span) across the Chattahoochee River. The replacement bridge will replicate the length, height, and form of the existing Pennsylvania Petit truss span.

CHA is responsible for bridge design, developing 14 different bridge alternatives as part of a bridge-type study. The preferred bridge-type alternatives were refined through collaborative design charrettes that involved an extensive list of stakeholders: City of Duluth, City of Johns Creek, Gwinnett County, Fulton County, Fulton County Water Authority, Georgia DOT, and National Park Service. Public support and excitement for the project is very strong in the communities on both sides of the Chattahoochee River because of the impactful renderings and innovative bridge design presented to the public in a series of public meetings.

PEDESTRIAN BRIDGE

Albany Shaker Road & Watervliet Shaker Road Reconstruction CHA completed the scoping, expanded project proposal, environmental studies, preliminary design (EIS preparation) and final design for improvements for two county-owned, urban arterials to meet existing and future traffic demands. The final project included the complete reconstruction of Albany Shaker Road and Watervliet Shaker Road on new alignment with widening to four lanes. Sidewalks were included in key areas, and a separate multi-use path links the Ann Lee Pond Nature and Historic Preserve at the south end of the project to the Airport Park business park at the north end of the project. The project also included design of a bridge to carry a new multi-use path over Watervliet Shaker Road and a four-cell box culvert to convey Shaker Creek under Sicker Road.

PEDESTRIAN BRIDGE

New Pedestrian Bridge over Manning Boulevard CHA completed the planning, design and construction inspection of a new three span, 300-foot-long bridge providing pedestrian access over Manning Boulevard to the Arbor Hill Elementary School. The bridge consists of a main, pre-fabricated truss span with steel, two girder approach spans. One approach to the bridge consists of two pedestrian paths: one is an ADA compliant “switchback� walkway and the other a bypass walkway with a curved alignment. A 130-foot-long retaining wall was required to accommodate the switchback walkway within the available right-of-way. The other approach consists of a ramp structure comprised of a concrete slab supported on a wall system. Due to the poor quality of the soils, a rammed aggregate column stabilization system was employed for all structural foundations. Architectural treatments and decorative lighting were incorporated throughout the project. Additionally, a plaza was designed at the end of the structure / entrance to the school that includes a concrete panel for exhibiting tiles painted by the students.

PEDESTRIAN BRIDGE

Rivertown Trail Newburgh’s Rivertown Trail is a three-phase greenway/trail project planned to connect Angel Mounds historic site with the Newburgh Lock and Dam park via new construction and designation of existing street and trail along the Ohio River. CHA was the project’s design engineer during the third phase.

Phase III of this federally funded trail project provides an additional .75mile segment to the existing path network, extending westward from the previously constructed phases. The east terminus of Phase III begins at the B. Gene Aurund Trailhead, located near the intersection of SR 662 and Frame Road/Yorkshire Drive. The path parallels SR 662 until the west terminus at the intersection of SR 662 and Pollack Avenue. Although in proximity to SR 662, this phase of the trail follows a meandering alignment that separates it from the existing roadways, thus offering users more of a ‘greenway’ experience.

This segment provides access to the Walmart neighborhood store that was constructed in 2016 in the southeast quadrant of the SR 662 and Ellerbusch Road Intersection. The path also provides a much needed pedestrian-friendly connection to the Newburgh Junior Baseball Complex located on the south side of SR 662 between Pollack Avenue and Ellerbusch Road. A pedestrian bridge was erected so that users can safely cross the drainage ditch located along the east side of Ellerbusch Road.

The path consists of a 10-foot wide asphalt pavement and sod shoulders, allowing for comfortable two-way traffic for pedestrians, joggers, bicyclists, and other non-motorized users.

PEDESTRIAN BRIDGE

Dutchess County Rail/Trail Project Route 82 to Creek Road CHA has been serving Dutchess County on a multiple year/phase contract to convert a 12-mile-long portion of abandoned railroad bed to a pedestrian trail. The design featured paved and soft-tread paths, 14 roadway crossings, 16 access points, 4 single-span bridges, one multispan bridge, and culvert and railroad rehabilitations. The project included the reuse of the historically-significant Dover Furnace Bridge, which had been removed as part of a separate project. CHA used the bridge to provide access to the trail over Wappingers Creek from a new trailhead.

PEDESTRIAN BRIDGE

Canalway Trail System – Amherst to Lockport Phase 1 CHA was responsible for the final design and engineering for the completion of the Canalway Trail from Tonawanda Creek in Amherst to the existing locks on the Erie Canal in the City of Lockport. This project included design of a 6.5-mile section of a 10-foot-wide off-road trail along the Canal through dense woods and through large spoil piles created when the Canal was constructed in its current location in the early 1900’s. This project also included development of a 1.5 mile on-street trail system following City Streets. The project involves construction of 3 bridges over waterways, 1 box culvert and approximately 1,100 feet of retaining wall. The project was constructed in two phases at a total cost of $7.5 million.

PEDESTRIAN BRIDGE

Industrial Heritage Trail over Beaver Brook CHA was engaged by the City of Keene to provide full engineering and landscape architectural services in the design of the one-mile segment of the bikeway network running through the historical industrial area of the City. The design effort of this TEA 21 funded project included a Master Plan of improvements and redevelopment of the trail corridor, construction of a new pedestrian bridge over Beaver Brook, multi-use trail design, landscape design, drainage design, hydraulic analysis, and full State permitting for the project.

PEDESTRIAN BRIDGE

Covington Circle Trail This project the design and construction inspection services of a new trail to accommodate pedestrians and bicycles developed by the Covington Community Foundation. This federally funded development provides residents with a recreational facility that will improve their quality of life.

The trail length is approximately 3.2 miles starting at the city park on the north side and crossing Mallory Branch at two locations ending at Pearl Street. The stream crossings were accomplished by removing and rehabilitating a historic two-span Fountain County truss bridge and taking each span to the two different Mallory Branch crossings.

Several truss members were replaced or strengthened due to extensive deterioration. New abutments were constructed to support the trusses at their new locations.

The trail consists of 12-foot wide asphalt pavement with two-foot shoulders. It incorporates several amenities including rest areas, trail heads, and landscaping for the users.

CHA’s responsibilities included the trail design, truss bridge rehabilitation, drainage design, permits, preparation of construction documents, and construction inspection.

PEDESTRIAN BRIDGE

Broadway Street Bridge over Wolf Creek CHA was responsible for the development of design and construction plans for replacement of the Broadway Street Bridge over Wolf Creek in downtown Dayton, Ohio. In addition, CHA created environmental documentation, ecological surveys and aesthetic treatments.

Our team developed multiple aesthetic concepts for the City of Dayton to present at a public meeting. This project had a significant amount of bike and pedestrian traffic with the bridge located in close proximity to a newly reconstructed public school. The aesthetic color scheme for the bridge was created based upon the school’s concepts. After the public meeting was held and documented, the City of Dayton selected the preferred alternative to advance to final design and plan development.

CHA utilized newly developed pre-stressed hybrid beams for this project to provide for a more slender appearance and to satisfy the hydraulic criteria. In addition, variable overhangs were used to create the bumpout overlook areas as shown in the renderings.

PEDESTRIAN BRIDGE

Canalways Trail Extension - West Shore Trail The Canalways Trail extension project consists of extending Onondaga County’s West Shore Trail, which is a non-motorized multi-use transportation trail, from the existing trail terminus at the NYS Fairgrounds parking lot to Hiawatha Boulevard, a distance of approximately 2.3 miles to the southeast. This project is currently funded under the Transportation Enhancements Program. The project includes a 1,400-foot bridge carrying the trail across the CSXT right-of-way.

INNOVATIVE BRIDGE

Social Circle—Fairplay Road at Hard Labor Creek Reservoir over Hard Labor Creek and over Reedy Creek This project required an innovative design for new crossings to be constructed in advance of the development and impoundment of the 1400 acre Hard Labor Creek Reservoir. The main crossing involved a new 5-span, 750 ft long bridge supported on tall reinforced concrete hammerhead piers. Unique to this crossing are the structural and geotechnical designs that had to account for a number of unique reservoir conditions, from prior to impoundment, to full pool, to wave and wind actions for the revetment design, to rapid and emergency drawdown situations.

At the secondary crossing, CHA designed an innovative multispan concrete bridge that was constructed directly over an existing concrete box culvert which was utilized to maintain the flow of the Reedy Creek during construction of the overhead bridge.

This project won the ACEC Georgia 2016 Engineering Honor Excellence Award..

SIGNATURE BRIDGE

Edwin C. Moses Boulevard over Wolf Creek Bridge Replacement CHA was responsible for the development of design and construction plans for replacement of the Edwin C. Moses Boulevard Bridge over the mouth of Wolf Creek in downtown Dayton, Ohio. In addition, CHA created environmental documentation, ecological surveys and aesthetic treatments.

Our team developed multiple aesthetic concepts before completing final design and plans. Based on a weighted decision matrix, the client selected a streamlined, modern bridge with a cable-stay tower.

CHA performed bridge design, roadway design, drainage design, traffic control layout, lighting design and right-of-way engineering. This project also required extensive coordination CHA, the City of Dayton, ODOT District 7 and Central Office, the Ohio State Office of Historic Preservation, Five Rivers Metro Parks department and the Miami Conservancy District. The new bridge replaces the existing two-span filled earth concrete arch bridge with a new, two-span beam bridge utilizing prestressed concrete U-beams – the first of their kind in Ohio. The superstructure and substructure have unique aesthetic details, developed with consideration of the Wright-Dunbar area nearby. The slender, streamlined appearance of the U-beam superstructure blends with the 60 ft-tall concrete tower with cable stays.

The existing roadway is a three-lane, urban arterial street within the City of Dayton. The roadway is reconstructed at each bridge approach, including new sidewalk entrances to the adjacent parks
