At RK&K, you’re in
the driver’s seat.
At RK&K our team members aren’t just building their careers, they’re building the environment in which they work each day. Everyone has a voice, and everyone listens. If you have a question, just ask.
Whether a complex, multi-discipline project or a small logistical challenge,
we approach everything with the same philosophy—every problem
deserves a solution driven by thought and creativity.
RK&K served as the lead designer for the widening and improvements of a critical 12.8-mile stretch of I-40, spanning from the I-40/I-440/US 64 interchange in Wake County to north of Cornwallis Road in Johnston County.
RK&K worked with PennDOT since 2013 to design a solution to mitigate difficult traffic conditions at the intersection of State Routes 209 and 115 in Monroe County.
This $463 million design-build replacement located on U.S. 301 was completed months ahead of schedule and connects Charles County in southern Maryland and King George County in northeast Virginia.
The Woodrow Wilson Bridge now serves as a vital link for the region, supporting economic growth and enhancing the quality of life for millions of residents.
Upgraded both liquids and solids treatment systems at the 20.5 MGD Fritz Island Wastewater Treatment Plant to comply with a consent order and more stringent discharge permit.
A significant safety improvement program for pedestrians, cyclists and drivers along a mile of San Martin Drive at the Johns Hopkins University Homewood Campus.
The goals set for this project and the site conditions made this superstructure replacement a complex project that required a creative, outside the box design solution.
