Before beginning the design for this project, the City completed a traffic study on this corridor to gather data on existing conditions. Currently, Ridgeview Road is at the upper threshold of the capacity of a two-lane street. During peak traffic times, there are few gaps in the flow of through traffic on Ridgeview Road, which leads to long delays for drivers on the side streets who are exiting the residential neighborhoods. The lack of left-turn lanes along this section of Ridgeview Road has resulted in a number of rear end crashes, as drivers block the through lanes while waiting to turn left. Overall, the crash rate for this section of Ridgeview Road is more than five times higher than the statewide average for similar types of streets.
The Ridgeview Road, 143rd to 151st, Improvements project will widen the existing roadway from its current two-lane section to a three-lane section, with the center lane being a dedicated two-way left turn lane. Additionally, two roundabouts will be constructed at the intersection of Ridgeview Road and Sheridan Bridge Lane and at the intersection of Ridgeview Road and Frontier Lane.
The traffic study analyzed the impact of traffic signals at these two intersections, but ultimately the roundabouts provide shorter traffic queues on both the side streets and Ridgeview Road. These traffic improvements, along with the construction of Mahaffie Street to the west (to be completed in 2020), will accommodate both current and future traffic flows.
In addition to the roadway improvements, this project will include:
- five-foot wide bike lanes
- five-foot wide sidewalk along the west side of the roadway (existing sidewalk is four feet)
- eight-foot wide shared use path along the east side of the roadway (existing sidewalk is four feet)
Construction on utility relocations should begin this summer and be completed by the end of 2020. Construction of the roadway improvements is scheduled to begin in March 2021.
