I-229 EXIT 4 (CLIFF AVENUE) CROSSROAD CORRIDOR STUDY

Cliff Avenue is a highly traveled commuter route for those attending Lincoln High School, coming from SE Sioux Falls and Harrisburg, and for those that work at Avera McKennan Hospital. As the City of Sioux Falls continues to grow to the south and east Cliff Avenue traffic volumes will continue to grow. It is important that we are planning for how capacity improvements could take place at this interchange. Through public meetings it has been conveyed to the study team that congestion is a concern as well as it is getting harder and harder to make a left turn from northbound Cliff Avenue to southbound I-229. This configuration certainly causes challenges in those peak periods of the day when high amounts of southbound traffic is coming along Cliff Avenue or from 41st Street. The study team based on preliminary analysis as being conducted for this overall study has determined that additional study and time needs to be put into this corridor to ensure we are planning for the proper improvement over the next 20-30 years.

In 2016, a study will be conducted to determine what improvements are necessary for the Cliff Avenue interchange to continue to serve the variety of users that it does today in the year 2035.
