About this file

This document is a set of bridge drawings and specifications for the rehabilitation of the Big Thompson River Bridge located in Rocky Mountain National Park, Colorado. The key details are:

The drawings include plans, elevations, sections, and details for the repair and replacement of the bridge's deck joints, concrete deck overlay, steel girders and railings. The work involves removing and replacing the existing aluminum railing with a new steel tube-backed timber bridge railing system, repairing the concrete deck, and applying a thin bonded epoxy overlay. Estimated quantities are provided for key pay items such as concrete, reinforcing steel, steel railing, and epoxy overlay. The specifications reference the AASHTO Standard Specifications for Highway Bridges and FHWA Standard Specifications for Construction. The work is to be performed under Federal Contract Opportunity 16efc3b012fb4cd3bace335defc1dd37 for the "ROMO 327127 Bridge Preservation" project, issued by the National Park Service. No additional details on the solicitation, award, or pricing are provided in this document.
