Interstate 15 Virgin River Bridge No. 1 Study


The Arizona Department of Transportation and the Federal Highway Administration is holding a public hearing Wednesday, Nov. 29, in Littlefield, for the I-15, Virgin River Bridge No. 1 Draft Environmental Assessment.

Age, increased truck use, weather, and de-icing salts have all contributed to heavy wear on the I-15 roadway and the eight Virgin River bridges within Arizona. FHWA identified the need to repair all of the bridges within this segment. Because the structural assessment of Bridge No. 1 identified it as structurally deficient, ADOT has prioritized efforts to rehabilitate this structure. Based on an assessment of past, current, and forecasted conditions of I-15 and Bridge No. 1 within the study area, the following issues surrounding the bridge have been identified as warranting a need for action: repairing structural deficiencies, the ability to accommodate high volumes of truck traffic, the need to support interstate and regional travel, and controlling unauthorized use of the ROW.

The purpose of the proposed project is to maintain I-15 as a regional traffic corridor for the long-term by remedying the Bridge No. 1 structural deficiencies so that I-15 can continue to accommodate truck traffic and serve as a regional traffic corridor that facilitates the movement of people, goods, and services while minimizing maintenance requirements. This action would help ADOT meet its long-range goal of maintaining I-15 as an essential trade and truck route linking Nevada, Arizona, and Utah.
