The 69th Street and Southeastern Avenue Intersection

 

The City of Sioux Falls Engineer’s Office retained Sayre Associates to provide civil engineering and construction administration services for 2 intersecting arterial streets in southeastern Sioux Falls.  The innovative design included a modern roundabout intersection as a traffic safety and calming device.  Sayre successfully teamed with HR Green on the geometric design of the roundabout.  The project design team worked in close coordination with an adjacent grade separation project on 69th Street performed by HR Green.  The projects were also constructed concurrently which made the construction phasing critical.  Sayre served as the prime consultant on the construction administration phase of the projects.  

The project involved several public meetings to describe the project and garner public support.  Individual meetings were also conducted with landowners, utility company representatives, and other government agency officials.  The successful project was completed on schedule due to the team effort and assigning the appropriate staffing levels with the proper engineering expertise.
