I-5 Tumwater to Mounts Road Corridor Planning and Environmental Linkages Study

Planning study news

In 2018, the Washington State Legislature funded a corridor planning study of Interstate 5 between SR 121 in Tumwater (Exit 99) and Mounts Road near DuPont (Exit 116) to develop mid- and long-term strategies for improving the region's transportation system. The study strategies that were developed have expanded into the Planning and Environmental Linkages Study.

Timeline
Spring 2020 - Fall 2021
Status
In progress
Budget
$2,250,000

Purpose

The "Planning and Environmental Linkages" (PEL) study will build upon the goals and strategies outlined in the original 2018 corridor study. This PEL study represents a collaborative and integrated approach to transportation decision-making that:

  1. Considers environmental, community, and economic goals early in the transportation planning process
  2. Uses the information, analysis, and products developed during planning to inform the environmental review process.
