The Kapa’a Stream Bridge, constructed on Kuhio Highway in 1953, was listed as one of the top 50 bridges in the state highway system in need of upgrade or repair. Its replacement is one of 10 bridge projects delivered as a partnership between the Hawaii Department of Transportation (HDOT) and the Central Federal Lands Highway Division of the Federal Highway Administration. As the structure is located on a critical connecting route north and south across Kauai and therefore heavily traveled, installing a temporary detour structure to reroute traffic flow during construction was a priority.

Modular detour bridging continues to be a popular, cost-effective method to provide a safe and reliable solution to traffic disruptions during infrastructure projects. Rapidly installed, it is a cost-effective way to help ensure the successful completion of jobs on or ahead of schedule.

The Acrow bridge designed for this project is 210 feet (64.01m) long and accommodates two lanes of traffic. Despite having an extremely tight work zone next to a busy highway that made assembly and installation complex, the build completed in just eight days in February 2020. The contractor, Hawaiian Dredging Construction, oversaw the erection of the structure and additional works to ensure the bridge opened the following month. The temporary bridge remained in place for the duration of the project and was de-launched in the summer of 2021.
