This project improves traffic movement by allowing a portion of traffic to bypass fully entering the Y roundabout by adding curb-separated right-turn lanes for vehicles headed to southbound 179 and northbound 89A. 

With no traffic it takes 12 minutes to travel from Bell Rock Blvd to the Y. In severe congestion it takes 36 minutes. This level of severe congestion occurred on six days between February 1 and June 4, 2017. With this strategy, a severely congested trip would be reduced from 36 minutes to 24 minutes.

Estimated cost is $2.7 million.
