BRIDGES AND HIGHWAYS

 

Construction of concrete and steel bridges, tunnels, deep foundations, and retaining walls is often technically challenging. This type of work is one of KBA’s specialties. Through attention to detail and persistent follow-through, KBA helps achieve the desired durability and quality of the structures while minimizing the impacts generated during the intensity of construction.

Arlington Valley Road

Client: City of Arlington

Location: Arlington, Washington

2018 - 2019

KBA provided full construction management support for construction of the Arlington Valley Road, a $4 million new route linking 74th Avenue NE to 191 Place NE, just west of Highway 9. The new road provides another option for businesses along busy 67th Avenue to reach the highway and serves commuters, pedestrian/bicyclists, as well as trucks hauling supplies and
products. The project constructed a new street having two traffic lanes and a center turn lane. The road is approximately three-quarters of a mile long. A paved pedestrian/bicycle path was constructed immediately adjacent to the new road. This project had been included in the City’s transportation plan for more than a decade but was delayed because of the recession. As the manufacturing industry in North Snohomish County expanded, the road had again become a priority. It also opened up properties to development that didn't have transportation access prior to the new construction.
