About this file

Written by GovTribe AI ·

This is a concept exhibit prepared for the City of St. George, Utah, depicting the design specifications for a 95-foot span, 10-foot wide prefabricated pedestrian bridge to cross the Virgin River Trail over the future George Washington Boulevard extension. The bridge design includes a concrete deck with reinforced steel construction, weathered steel finish structural components, and cable railing systems with 1/4-inch diameter stainless steel strands spaced at 3-inch centers. The structure features a top deck elevation of 2571.94 feet with minimum bottom chord elevation of 2568.94 feet, driven pile foundations, concrete abutments with wing walls, and rock rip-rap erosion protection. The bridge incorporates a 42-inch guardrail with 30-inch height under the structure extending to 42-inch height at the ends of the mechanically stabilized earth (MSE) wall with grape stake texture facing. Additional components include a 6-inch reinforced concrete deck to be poured in place after installation, galvanized deck forms, floor beams, toe rails, and an 8-foot maximum railing height. A 3/4-inch anchor bolt system with 6-inch minimum embedment depth provides connection to setting and bearing plates supplied by the bridge manufacturer.

The document serves as a technical reference guide for the solicitation indicating the City of St. George is seeking bids for prefabrication and delivery of this bridge structure. The concept exhibit provides detailed elevation views, section details, and material specifications necessary for qualified bridge manufacturers to submit responsive proposals. No pricing information, bid due dates, award timelines, or contract term details are contained within this technical drawing document.
