The intersection of Roberts Drive and State Route 169 (SR 169) in Black Diamond, Washington has been a troublesome juncture for drivers for a long time due to limited sight lines. This problem has only been made worse with the increase in traffic through the community due to developments such as Ten Trails, a master-planned community that Goodfellow Bros. is currently working on.
Working with the City of Black Diamond’s Master Development Review Team (MDRT), Goodfellow Bros., general contractor for CCD Black Diamond Partners, LLC., sought to improve this dangerous intersection and make it safe for the community by constructing a T-junction style intersection.
To achieve this, GBI removed the old Roberts Drive ramps that tie to SR 169, excavated new storm lines and constructed new paved roadways. The public safety road improvement project also included wetlands protection systems.
Erin Redmond, Project Manager with Goodfellow Bros., said, “While a short-term project, this intersection is heavily used by the community. We worked to complete the project as quickly as possible and made every effort to communicate as early and often as we could with residents to minimize disruption.”
With careful planning, crews were able to complete the project, along with inspections by Washington DOT inspectors, four days earlier than scheduled.
“Overall, feedback from residents has been very positive,” added Redmond. “The new intersection, while a short-term fix, is safer for all drivers.”
CCD Black Diamond Partners is developing plans for a long-term fix to the intersection that is designed to accommodate the region’s continued growth.
Since the earliest days of the master-planned community development at Ten Trails, CCD Black Diamond Partners, LLC. and Goodfellow Bros. have constructed a number of community improvement projects just like the T-junction. These projects range from filling potholes at the community center parking lot to restriping major roadways to a new sidewalk connection from the city center to the new master planned community.
