OTIA III State Bridge Delivery Program
Environmental Program Overview
In 2003, the Oregon Legislature enacted the third Oregon Transportation Investment Act, or OTIA III. This funding package provides more than $1.3 billion to repair or replace hundreds of bridges across the state in 11 years. 
To meet this challenge, ODOT formed the OTIA III State Bridge Delivery Program to assess bridge conditions and to manage bridge repair and replacement. Determining which bridges to replace and which could safely be repaired is a major task. In addition, bridge work must be done in ways that minimize impacts on freight movement, local communities and recreational traffic, and that comply with complex local, state and federal regulations.
ODOT's OTIA III environmental strategy is critical to the success of the bridge program. This integrated approach is designed to enhance environmental stewardship, encourage interagency collaboration and streamline environmental permitting processes for faster, more cost-effective project delivery.
The environmental strategy include seven key steps:
  1. Up-front context descriptions/baseline reports
  2. Programmatic, performance-based permits  
  3. Statewide mitigation banking program  
  4. Integrated data management  
  5. Stakeholder collaboration  
  6. Monitoring, evaluation and adaptation
  7. Training and education

OTIA III Bridges TransGIS
The OTIA III Bridges TransGIS Internet site contains baseline environmental data for OTIA III State Bridge Delivery Program. The site is a primary resource for project participants to collect information in a timely manner.
You can view and download a wide variety of GIS data, tabular data, and imagery collected for more than 400 bridges. Available data include bridge locations, bridge study areas, historic architectural resources, wetlands, botanical resources, 4(f) features, aquatic resources, floodplain boundaries, statewide aerial photography, USGS maps, and site photos. A user guide is integrated into the web site. Metadata detailing the GIS and how it was developed is also available.
To gain entry, enter your email address in the box near the top left of the welcome page. You will be guided through a brief authentication procedure. Project-approved users are granted access within a few business days. You may share this link with other contractors and agency representatives involved in the bridge program.
