PROGRAM - STAGES UNDER DEVELOPMENT
The bridge program is divided into five stages to keep commerce moving throughout key freight and transportation corridors.
To keep traffic moving throughout the state, work on the OTIA III State Bridge Delivery Program has been divided into stages. OTIA III bridges are packaged into bundles for cost efficiency and to make a variety of project sizes available to Oregon design and construction firms.
Stage 1 focuses on the routes from Klamath Falls to Portland via U.S. 97 and U.S. 26, and from Bend to Ontario via U.S. 20. Bridges along these corridors need to be open to heavy and over height / over width truck traffic to provide an alternate route during Stage 2 construction on the interstates. To meet this goal, ODOT packaged Stage 1 bridges into bundles for design and construction work.
Stage 1A is comprised of bridges that faced imminent restrictions. ODOT needed to replace or repair them in order to eliminate, or minimize, load-restricted postings while Stages 2 through 5 are being delivered. Some of these bridges have been replaced and others permanently repaired. The remainder have been temporarily repaired to avoid restrictions and then re-assigned to their original stages for completion.
Stage 2 is the largest stage, both in funding and in the number of projects. It addresses the bridges on two major passenger and freight routes in Oregon: Interstate 84 and the northern portion of Interstate 5 from the Washington border to the Eugene-Springfield area. Notable Stage 2 projects are the Snake River crossing on I-84 at Ontario and bridges in the Columbia River Gorge National Scenic Area.
Stage 3 includes stage bridges on southern I-5, from Eugene to the California border, addressing bridge improvements to a significant portion of a major freight and passenger traffic corridor. It is the second largest stage.
Stage 4 includes replacements or rehabilitation of bridges on vital freight corridors connecting coastal communities to I-5 and I-84 as well as key north-south routes in eastern Oregon. This stage includes bridges in the coastal corridor north of Coos Bay and bridges in central and eastern Oregon.
Stage 5 addresses routes and connections for rural and remote areas within eastern and central Oregon and the coastal corridor south of Coos Bay. These include routes critical to passenger transportation and the transport of agricultural, timber, and aggregate products and loads of over 100,000 pounds.
OTIA III projects that will be managed by ODOT regions
Many OTIA III projects are located near projects already authorized under the Statewide Transportation Improvement Program. To limit the impact on traffic, these projects have been integrated with the planned STIP projects and will be managed by ODOT regions.
