The street, which cuts through residential neighborhoods, has a history of speeding concerns, according to November presentation documents. The current speed limit is 25 mph, but the majority of people are driving over that, per the presentation. The traffic calming project looks to mitigate this safety issue.
The details
Traffic calming measures consist of horizontal and vertical obstructions, lane narrowing and other features that use self enforcing physical or psycho-perception means to produce slower speeds, according to the presentation.
City staff have allocated $650,000 for the project, but may exceed that amount as staff are considering Americans with Disabilities Act compliance issues that may increase the project scope, said Senior Traffic Engineer Sirwan Shahooei in an email.
Consultants are working on the design package and expect to bid the project in spring 2025, Shahooei said.
Zooming in
According to the presentation, the city has added signage since the 2021 Castle Hills annexation and has performed targeted enforcement. The city of Lewisville does not use speed humps or speed tables due to negative affects to emergency response times as well as other unintended consequences.
Mitigation efforts could include the following:
- Bump-outs
- Lane narrowing by moving curbs or other means
- Parking bays and bike lanes
- Painted crosswalks
- Traffic control devices
- Medians
- Traffic circles/roundabouts
Construction is expected to begin in summer 2025, Shahoeei said. While the road will remain open, residents can expect intermittent lane closures throughout the construction process.
