- A major milestone is taking shape in Tehaleh!

At the New Rhodes Lake Road E project in Tehaleh, the MacKay team was out checking survey control as construction continues on this major infrastructure improvement. The team is providing surveying and construction staking services for the new 1.7-mile multi-lane arterial connecting Tehaleh to SR 162.

The work also includes a new roundabout, bridge replacement over the Puyallup River, and a hillclimb rising more than 400 feet in elevation. Once complete, this roadway will serve as the primary entrance into the Tehaleh community.

This project is especially meaningful for our team because MacKay opened our Federal Way, WA, office in 2011 to support the Tehaleh Development. It is exciting to see construction progressing and this important connection becoming a reality. We are proud to continue supporting projects that help communities grow and stay connected.

Nelson Geotechnical Associates brings decades of expertise in geotechnical engineering throughout Washington and the Northwest, while Curran-McLeod, Inc. adds deep experience supporting municipalities and special purpose districts with water, wastewater, stormwater, and transportation infrastructure projects.

Most importantly, both firms share MacKay’s commitment to strong client relationships, technical excellence, and community impact.
