Lake Road and Pioneer Drive Improvements
With continued traffic volume growth on Pioneer Drive and Lake Road, the existing all-way stop intersection is beginning to show signs of degradation in both pavement condition and traffic capacity during peak times. In conjunction with the other planned roadway and trail improvements along Lake Road, the City of Woodbury is studying potential improvements for this intersection to improve traffic capacity and pedestrian safety.
Both Middleton Elementary and Lake Middle Schools are located in the southwest quadrant of the intersection and generate large amounts of vehicle and pedestrian traffic. The city's evaluation will include analyzing the morning school dismissal and evening peak hours to forecast year (2042) traffic volumes. The evaluations include assessing traffic volumes; intersection and roadway safety; pedestrian and bicycle safety; traffic operations; and other factors such as cost and right-of-way impacts.
Two options were analyzed for this intersection. The first option would be to convert this intersection into a signalized intersection and the other to construct a roundabout. An initial review indicates the existing all way stop would result in unacceptable delays and congestion in the design year of 2042. Both the signalized intersection and a roundabout may allow optimal performance into the future.
Roundabout Controlled Intersection
Why a Roundabout? - Safety Features
Fewer & Less Severe Crashes
Slower Speeds for All Vehicles
Extended Medians & Additional Pedestrian Improvements

"Roundabout U" is an outreach program of Washington County to provide guidance and information on a variety of topics related to roundabout design and usage, including instructions for drivers, pedestrians, and cyclists.
Community feedback will be considered prior to making design recommendations for the project. These recommendations will be used to prepare a preliminary report identifying the improvement scope and estimated project costs. A Public Improvement Hearing will be held to present the proposed improvements for City Council consideration. The final design of the project will begin after the Public Improvement Hearing and the project will tentatively be scheduled for construction in summer 2022.

Resident feedback was collected in September 2020 relating to the existing intersection conditions and potential traffic signal or roundabout improvements. Over 260 responses were received with feedback supporting the need for intersection improvements. Feedback included:
- A desire for traffic calming strategies
- Reduced speed limits
- Limiting traffic delays
- Clear signage at the intersection for both traffic and pedestrians
- A need for better walking and biking infrastructure including consolidated crosswalks, rectangular rapid flashing beacons, increased pedestrian visibility
Another common response was a request for grade-separated crossings for pedestrians. Both bridge and tunnel alternatives were evaluated and it was determined that due to right-of-way needs, utility conflicts, adjacent property impacts, availability of alternate design options and costs of these improvements, grade separated trail crossings are not a recommended solution for this intersection.
In April 2021, resident feedback regarding the proposed design was collected.
