About this file
This is a structural drawing set for the North Connector Bridge Replacement project in Colorado (Project Number 25-104.01), prepared at the 90% design phase. The project involves the replacement of a pedestrian bridge featuring a prefabricated steel truss design with a clear span of 100'-7" and an 8'-0" out-to-out width. The bridge will accommodate a 6'-0" clear trail width with 3'-0" clearances on each side, supported by drilled caisson foundations at both abutments. The longitudinal section indicates a 1.5% trail slope with profile grade elevations of 5558.70 at both abutment seats, and the design accounts for 100-year and 10-year water surface elevations of 5559.4 and 5557.1, respectively. The structural plan includes welded steel trusses with a minimum low chord elevation of 5556.70, reinforced concrete approach slabs, pedestrian railings, and safety rails, with all truss specifications and requirements detailed in Section 628 of the project specifications.
The drawing set represents the technical design documentation for construction bidding purposes, showing coordinate locations (N: 1656229.48 E: 3186397.04 at Abutment 1; N: 1656299.70 E: 3186471.84 at Abutment 2) and detailed dimensions for contractor verification and fabrication. The bridge manufacturer will design the reinforced concrete slab and truss systems, with payment limits established by the concrete sealer item (Item 515). All trusses and railings depicted are general representations subject to final verification by the truss designer, and additional information regarding horizontal control line and profile grade data is referenced on separate trail plan and profile sheets.
