About this file
This is a structural drawing set for the North Connector Bridge Replacement project in Colorado (Project No. 25-104.01), prepared at 90% design completion. The project involves the replacement of a pedestrian bridge with a prefabricated steel truss structure spanning 100 feet 7 inches between abutments. The bridge will feature an 8-foot out-to-out width with a 6-foot clear deck for trail use, constructed with welded steel trusses and reinforced concrete approach slabs at both abutments. The structure includes drilled caisson foundations, safety rails, pedestrian railing matching the bridge design, and hand rail brackets. The design accommodates a 1.5% trail grade with specific elevation requirements, including a minimum low chord elevation of 5556.70 feet, and accounts for 100-year water surface elevation of 5559.4 feet. The bridge connects the North Connector trail segment, with final grades and approach slab details shown in the typical section and profile views.
The drawing set represents the technical specifications and site layout for construction bidding purposes, with all dimensions, elevations, and structural details verified by the bridge manufacturer's design requirements. Construction must comply with Section 628 bridge specifications, and additional trail plan and profile sheets provide horizontal control line and profile grade information. The project coordinates are established with benchmark locations at both abutments (Abutment 1: N1656229.48, E3186397.04; Abutment 2: N1656299.70, E3186471.84), enabling precise field layout and construction verification during implementation.
