News Release

Mariposa Causeway Ribbon Cutting At Mariposa Park (Photo) - 04/29/26

CORNELIUS, OREGON – After years of planning and one year of construction, the Mariposa pedestrian Causeway is ready to welcome community members and visitors. The City of Cornelius will host a ribbon-cutting ceremony on Saturday, May 9 at 10:00 a.m. at Mariposa Park (1297 S Quartz Dr, Cornelius, OR 97113), where attendees will be invited to walk the new causeway.


Mayor Jeffrey Dalin will provide remarks on the project, along with Metro Councilor Juan Carlos Gonzalez and representatives from the Tualatin Riverkeepers. The event will also feature the unveiling of a new interpretive sign highlighting the Tualatin River and its significance.


“This project reflects the impact of strong partnerships and long-term community investment,” said City Manager Peter Brandom. “We have worked alongside many partners to make this project a reality, including Holt Homes, who built much of the Laurel Woods neighborhood, former long-time owners of the beautiful land, and Metro, who provided grant funds for design and engineering of the causeway, and who now owns the adjoining natural area. Together we’ve created a space that enhances access to nature and offers a new amenity for both residents and visitors.”


The Mariposa Causeway is an important addition to the City’s growing trail network. First envisioned in 2009, the project supports the City’s goal of developing a connected bike and pedestrian system along the edge of the Laurel Woods neighborhood, as outlined in the 2009 Cornelius Parks Master Plan.


Expanding access to the Tualatin River is the City’s next priority. Currently, there are no direct public access points to the river, which flows along the city’s southern boundary. The City is working with Metro and other partners to develop safe and accessible access points that will allow community members and visitors to experience the historic river.


Community members and regional neighbors are encouraged to attend the ribbon-cutting celebration and experience the new causeway.
