Cohoes Black Bridge rail-to-trail rehabilitation

  • Celebration on the newly opened Black Bridge

This bridge rehabilitation project converted the former Delaware & Hudson Railroad Bridge over the Mohawk River (the "Black Bridge") into a scenic bicycle and pedestrian rail-to-trail crossing between Van Schaick Island and Green Island. This project is a critical component of a larger connector trail linkage planned from the Mohawk Hudson Bike-Hike Trail to Peebles Island and the Lake Champlain Bikeways network. The Cohoes Black Bridge will be a connecting route along the New York State Canal Corp trail system.  The bridge provides a connecting route between the Mohawk Hudson Bike-Hike Trail and the Champlain Canalway Trail.  A cyclist can now leave the Corning Preserve and travel to Peebles Island and the Champlain Canalway north without having to cross SR787. B&L provided preliminary and final design services as well as full-time construction administration and inspection services.

B&L provided engineering design services for the Griffiss Veterans Memorial Parkway located in the former Griffiss Air Force Base.  The design involves the incorporation of a multi-modal transportation infrastructure within a growing commercial corridor.  B&L designed two roundabouts, a multi-use path, sidewalks, decorative lighting, and landscaping to complement the existing topography.  With traffic calming and multi-modal transportation accommodations the key project objectives, the corridor design builds upon the base parkway cross-section that  includes two travel lanes in each direction, separated by a raised, landscaped median.  A continuous concrete sidewalk parallels the northbound lanes, with a multi-modal trail on an independent alignment to the west – linking the business park to the Black River Canal Trail. The first roundabout consists of a 4-leg system to replace an existing 4-way signalized intersection.  The second two-lane roundabout replace an existing Y-type stop sign controlled intersection allowing for a potential development of a fourth leg.

Beach Road, a fourā€lane, 1.1-mile urban collector, is the principal transportation corridor serving the south shore of Lake George, linking the Lake’s east shore, Million Dollar Beach, and Fort William Henry to the Lake George Village Center and the greater resort area, including main street hotels, shopping, attractions, and restaurants. The project involved the repair of deteriorated pavement, drainage improvements, the first use of heavy-duty (HD) porous asphalt pavement in New York, reconfiguration of two intersections, and daylighting of a culverted section of the West Brook that flows into Lake George.




Water Street over Ganargua Creek Bridge Replacement

Water Street Bridge

Water Street Bridge

  • Water Street Bridge
  • Water Street Bridge over Ganargua Creek
  • Relocated Sanitary Sewer Main

The existing Water Street structure was a three-span, multiple timber girder superstructure with a timber deck supported by pile and lagging abutments.  The steel pile piers were deteriorated and the abutments began to lean toward the creek. The project replaced the three-span structure with a single span structure and eliminate the piers in Ganargua Creek.  Design features for this replacement included design survey and mapping (including stream cross sections), development of a design report, a Phase I archeological survey, compliance with environmental guidelines and regulations, and participation in public meetings. The replacement structure included the single-span, multiple steel girder superstructure constructed integrally with the cast-in-place concrete substructure. The substructure concrete was constructed with a simulated stone masonry facing to maintain the aesthetic of the surrounding area. The structure was also supported on steel H-piles. An existing forced sanitary sewer main was relocated onto the new bridge as part of this project.
