Bartlett Street

TRAFFIC ALERT: As part of the design, the four-way stop at Thornton and Bartlett Streets has been REPLACED with a two-way stop. There are stop signs now on Thornton Street, not Bartlett. Please be extra cautious because of this permanent change. City staff continue to collect speed and volume data on Bartlett Street to see how traffic is adjusting to the new roadway and intersection configurations. These summary reports of speed studies conducted at #314 Bartlett Street, located halfway between Thornton Street and Pine Street. The first was conducted in November 2019 before the reconstruction project, the second one in October 2025 after the completion of the project. The results indicate that the average speeds at this location have decreased from the previous average of 24 MPH to the current average of 21 MPH. Additional speed monitoring will continue to be conducted at locations along Bartlett Street between Dennett Street and Cate Street. For the March 27, 2024 public meeting presentation and video recording, additional background information and to sign up to receive weekly updates on the project, visit the project page.
