CRC - Final Report, 2012

This project, set up as a bi-state collaboration of Oregon DOT and Washington State DOT, explored options and developed proposals for improving the I-5 corridor between the two states. Following completion of the Final Environmental Impact Study, the locally preferred alternative (LPA) was defined to include a replacement bridge across the Columbia River, as well as light rail stations, highway improvements and bicycles and pedestrian pathways.

The project team calculated economic impacts and benefits of the CRC utilizing TREDIS to compare the LPA versus the No Build – as seen from the perspective of the region, the rest of Washington, the rest of Oregon, and California.

The TREDIS analysis examined project-related economic benefits in terms of landside traveler savings, marine navigation savings, and the economic effects of improved market access and connectivity.
