Claremont Boulevard Closure

Beginning November 3, 2025, Claremont Boulevard will be closed in both directions between Foothill Boulevard and Sixth Street to accommodate construction for the CMC Roberts Campus Sports Bowl project. This work will include installation of a new traffic signal, pedestrian pathway, and complete streets improvements, along with related utility upgrades. Detours will be in place to guide motorists around the construction zone. The project is expected to continue for approximately 10 months.

Local Roadway Safety Plan

The City has hired KOA to create a Local Roadway Safety Plan for the City of Claremont. The California Department of Transportation (Caltrans) established a program for cities to prepare a Local Roadway Safety Plan (LRSP) to identify safety needs and recommend projects to address these needs. This document serves as the LRSP for the City of Claremont.

Funded by Caltrans, an LRSP provides an opportunity for local agencies to evaluate roadway safety problems through data analysis and improve roadway safety through infrastructure implementation, education, and enforcement programs/campaigns. Preparing an LRSP creates a framework to identify and analyze safety problems and recommend safety improvements systematically.

An LRSP analyzes collision data, assesses infrastructure deficiencies through an inventory of roadway system elements, and identifies roadway safety solutions on a citywide basis. The State created the LRSP to help local agencies develop safety projects that can be submitted for funding as part of the Highway Safety Improvement Program (HSIP) and other funding programs sources such as the Safe Streets and Roads for All (SS4A) grant program. These programs require that an LRSP, or equivalent plans such as a Vision Zero Plan or Systemic Safety Analysis Report (SSAR), be completed in order to apply for available funding opportunities.

Towne Avenue Improvement Project

The City of Claremont recently improved Towne Avenue from Foothill Boulevard to Base Line Road utilizing a Complete Streets Design. The new street improvements incorporate design elements to reduce speeds and increase visibility for cyclists and pedestrians. The width of the lanes was reduced, new landscaped medians added, and protected bike lanes created in sections where space allowed. The City also added green paint to bike lanes in areas where drivers and cyclists are at a higher risk of colliding. Green bike lanes make drivers and bicyclists more aware of each other as they share the road. This increased visibility enhances safety by reducing collisions. The green paint does not change the rules of the road.
