Bridge Section


The Bridge Section is committed to providing innovative solutions for the design, construction, and maintenance of Idaho's transportation bridges and structures.

The Bridge Section develops plans, specifications, and estimates for bridges, sign structures, retaining walls, and other transportation structures. Reviewing shop drawings, falsework/formwork, and construction project support is an integral part of our mission. Bridge Section functions include reviewing consultant designs and providing assistance to the Local Highway Technical Assistance Council. The Bridge Section also performs biennial bridge inspections to insure safety for the traveling public in accordance with the National Bridge Inspection Standards (NBIS), develops repair recommendations for existing bridges, performs load ratings, and determines load postings and closings of deficient bridges. Other responsibilities include the development, implementation, and operation of the Bridge Management System to provide system-wide condition analysis and reporting to support bridge-programming decisions.

The NBI (National Bridge Inventory) which includes a complete inventory of Idaho's bridges and conditions can be found at the following link
