County Road 189 Bridge Replacement over Grunley Creek
This Locally Administered Federally Aided (LAFA) bridge replacement project was located approximately 17 miles south of Watertown, NY. The existing jack arch steel multi-girder superstructure supported on concrete abutments and founded on bedrock was structurally deficient and therefore replaced with 30’-6” clear span, metalized steel girders with a composite deck wearing surface, supported by semi-integral abutments found on bedrock. Project work included approximately 200’ of highway approach work, new guide rail, and re-shaping the existing drainage ditches. During construction, the traveling public was managed through use of an off-site detour. Lu Engineers provided preliminary engineering, final design, and construction inspection services. Key elements of the firm’s work included bridge design, hydraulic analysis, roadway design, environmental permitting/screenings, preparation of design reports, public participation/public information meeting support, right-of-way acquisition, bid phase services, construction management, and construction inspection.
