About this file
This is a 90% design drawing set for the North Connector Bridge Replacement project (Project No. 25-104.01) in Colorado, prepared under the supervision of professional engineers and dated August 28, 2026. The project involves the replacement of a pedestrian bridge with a prefabricated steel truss structure spanning 100 feet 7 inches (out-to-out) with an 8-foot clear width. The bridge design includes welded steel trusses with a reinforced concrete deck, drilled caisson foundations at both abutments, and approach slabs. Key structural specifications include a minimum low chord elevation of 5556.70, profile grade elevation of 5558.70 at both abutments, and the bridge is designed to accommodate a 100-year water surface elevation of 5559.4. The trail surface features a 1.5 percent slope with safety rails, pedestrian railings matching bridge specifications, and hand rail brackets. Coordinate locations are provided for Bridge Abutment 1 (Station 0+99.97, N:1656229.48 E:3186397.04) and Bridge Abutment 2 (Station 2+02.55, N:1656299.70 E:3186471.84).
The drawing set represents the structural and general layout plan, with typical section and profile views included to provide comprehensive design information for bidders and contractors. Construction specifications reference Section 628 for complete bridge requirements, and the document notes that truss dimensions and railing details shown are general representations requiring verification by the truss designer. Trail plan and profile sheets contain additional horizontal control line and profile grade information necessary for construction. This drawing is Sheet 2 of 2 in the drawing set and serves as the technical basis for solicitation and construction of the pedestrian bridge replacement project.
