269th/Pioneer Street and I-5 Interchange
The Port is proactively discussing options for a new interchange that will be able to accommodate the future industrial and residential growth in the 269th area. The Port is working with the City of Ridgefield, other developers and citizens on very early preliminary design and engineering so that current growth could protect the needed right-of-way and save costly time and money in the future.

I-5 and 219th Interchange
The Port is involved with the current proposals for the SR503/I-5 interchange to advocate for the preservation of a western access point that would enhance the infrastructure for future industrial development and distribute the local use by residents between the 269th and 219th interchanges.
SR501/Pioneer Street Rail Overpass
The Port is part of a group with includes the City of Ridgefield, Burlington Northern Santa Fe Rail Road, Washington Department of Transportation Rail Program and US Fish and Wildlife who are advocating the study of a creating a railroad overpass in downtown Ridgefield. The western continuation of Pioneer Street/SR 501 would: close three at-grade railroad crossings thereby improving safety and decreasing the freight travel time through the Portland-Vancouver rail corridor, provide reliable access to the Lake River Industrial Site, and cross Lake River to provide auto access to the Wildlife Refuge. Late in 2004 the U.S. Congress authorized $1 million in the Omnibus Appropriations bill to study the proposed project's feasibility and complete preliminary design and engineering. The Port serves as the lead agency on the project. Design, environmental and engineering work should begin in late 2005 when the federal funds become available.

North County Grid System
The Port facilitated a small group discussion of citizens who developed a "big picture" grid system to enhance transportation within the district on a long-term 20-year horizon. The group added only 10 and ½ miles of new road to enhance an existing 1 mile road grid. Working under agreed upon guidelines the enhanced grid system would: preserve I-5 for freight mobility by keeping local trips off the freeway, serve the growing number of business and residents, and promote the development of primary, secondary and local arterials consistent with the long-term vision of North Clark County as a job center serving the surrounding communities. Next steps for the project include discussions with Clark County to include the new roads in the County Road Atlas.
