Lake Road Improvements
Construction Update: Lake Road now open to all traffic
A roadway repaving project was completed during the 2022 construction season on Lake Road between Courtly Road and Tahoe Road, and between Woodlane Drive and Pioneer Drive. During the project, portions of Lake Road were converted from a four-lane roadway to a three-lane roadway to increase safety for vehicles and pedestrians. In addition, the intersection of Lake Road and Pioneer Drive was converted into a single-lane roundabout.
The road opened to all traffic Aug. 17.
As a part of that project, Lake Road between Woodlane Drive and Pioneer Drive was converted from a 4-lane to a 3-lane road.

This conversion increases safety by reducing crashes, increasing pedestrian safety, providing a shoulder, and promoting compliance with posted speed limits.
In 2016, the city conducted the Lake Road Restriping and Safety Improvements Study which determined the traffic volumes are acceptable to accommodate the 3-lane roadway conversion with improved traffic flow and operations.
The project also included repaving of the existing trails along Lake Road to improve the trail surface.
Pedestrian enhancements constructed with this project include refuge islands at the intersections of Lake Road and Oriole Drive, Camelot Drive, and Stratford Road. Rectangular rapid flashing beacons will remain at the intersection of Lake Road and Wyndham Way.
At the intersection of Lake Road and Pioneer Drive, a single-lane roundabout was constructed.
Enhanced Pedestrian Safety
Similar to the former all way stop, a roundabout requires all vehicles to slow down as they approach the intersection, navigate the roundabout, and pass through the crosswalks. The design promotes lower speeds along the roadway corridor while maintaining traffic and pedestrian flow. These slower speeds greatly reduce the chances of severe injuries, especially for pedestrians.
With the roundabout design, rectangular rapid flashing beacons were installed at key pedestrian crossings to provide increased pedestrian visibility and promote increased vehicular yielding compliance. These beacons were installed along the school walking routes to assist crossing guards in alerting incoming traffic that pedestrians are present and looking to make a crossing. These rectangular rapid flashing beacons are push button activated by pedestrians and have been shown to increase vehicle yielding.
The improvements were designed to address safety improvements identified in both Middleton Elementary and Lake Middle School's Safe Routes to School plans, as well as address the concerns and feedback that was received during the September public engagement efforts and provide the community with the best solution to aging infrastructure.
With continued traffic volume growth on Pioneer Drive and Lake Road, the former all-way stop intersection was beginning to show signs of degradation in both pavement condition and traffic capacity during peak times. It was decided that improvements to this intersection should take place in conjunction with the conversion project to reduce traffic impacts to one season.
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 included analyzing the morning school dismissal and evening peak hours to forecast year (2042) traffic volumes. The evaluations included assessing traffic volumes; intersection and roadway safety; pedestrian and bicycle safety; traffic operations; and other factors such as cost and right-of-way impacts.
A signalized intersection and roundabout were analyzed for this intersection after an initial review indicated the existing all-way stop would result in unacceptable delays and congestion in the design year of 2042.

Resident feedback was collected in September 2020 relating to the existing intersection conditions at Lake Road and Pioneer Drive 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.
