Roadways and Traffic Engineering
During our 27-year tenure in northern Arizona, we have provided engineering services for various roads and highways including Loos Drive in Prescott Valley and Beaverhead Flat Road in Yavapai County. For a more detailed list of relevant projects, please visit our contact page to request more information.
Loos Drive, Prescott Valley
This CDBG-funded project included the first three of the four phases planned for the improvements, which enhanced the Loos Drive roadway from Robert Road to Navajo Drive. The roadway serves Mountain Valley Park, along with retail spaces, residential subdivisions, and an elementary school. The projects included new asphalt; curbs; sidewalks; drainage structures; and storm drain installation. Challenges included a tight budget and accelerated design to ensure completion of paving prior to the re-opening of the adjacent Mountain Valley Elementary School in Phase 1. The Phase 2 and 3 work included widening the north side of Loos drive from Robert Road to Navajo Drive, including the frontage of the school. SWI provided the full design and construction phase services for the project.
Jack’s Canyon Road, Village of Oak Creek
The Jack’s Canyon Road Reconstruction Project focused on reconstructing approximately 5,000 linear feet of Jack’s Canyon Road in the Village of Oak Creek. Design services included traffic analysis for build-out scenario, sight distance analysis of existing vertical curves, and a frontage road for several lots with direct access to Jack’s Canyon Road. This project required careful consideration of vertical and horizontal realignment to improve sight distances, resolution of numerous underground utility conflicts, coordination with numerous affected property owners along the proposed route, and recommendations of an additional right-of-way.
Beaverhead Flat Road, Yavapai County
Beaverhead Flat Road was improved from a dirt road in to a two-lane paved facility that now provides access to the Sedona area and relieves traffic congestion on Highway 179 at State Route 89A. Design services included coordinating with local ranches for the design of two equestrian underpasses and avoiding several archaeological sites with vigilant design of the horizontal alignment.
North Bank Street Reconstruction, Kingman
The North Bank Street Reconstruction was a federally funded ARRA project to reconstruct approximately 2,000 feet of roadway in Kingman. Bank Street serves as a connector road for an industrial area which experiences heavy traffic from local trucking businesses. The City of Kingman contracted SWI to work within the ARRA funding requirements, including adherence to ADOT standards, to prepare plans for total reconstruction. The work included maintaining an inverted-crown profile for drainage. Bank Street was widened to two travel lanes, with two bike lanes, and included curb and gutter. The project improved traffic and drainage to the area. Environmental clearance for roadway improvements was also required, which included: archaeological, biological, and hazardous materials surveys.
