Street Projects/Construction Updates
Arrow Highway, First Street, & Indian Hill Improvements
The City has contracted Hardy & Harper, Inc. to complete the Arrow Highway Transit Improvements, First Street Pavement Rehabilitation, and Indian Hill Boulevard at I-10 Improvements.
Construction began on Monday, October 27, with work starting on the Arrow Highway Transit Improvements. The First Street Pavement Rehabilitation followed on October 31, and work on Indian Hill Boulevard (from San Jose Avenue to American Avenue) is anticipated to begin in mid-November.
This Friday and Saturday, November 7 and November 8, the City’s contractor will be crack-filling and performing deep removal and replacement of asphalt sections of First Street in preparation for paving operations to start on Monday, November 10. This work is necessary to stay ahead of the rain forecasted for late afternoon on Wednesday, November 12. A City-hired contract inspector will be on-site while these construction activities are being performed. Access to First Street will remain available with intermittent stops in traffic as necessary for this work to be completed, and vehicles traveling along First Street can expect delays during this time. Foothill Transit has been contacted regarding service at bus stops while this project on First Street is being completed, and detour signs will be placed at Foothill Transit’s discretion.
The project is expected to reach substantial completion—with temporary striping on First Street and Indian Hill Boulevard—before Thanksgiving. Final striping and overall project completion are scheduled for late December. Please note that these dates are subject to change due to weather or unforeseen conditions.
All roadways will remain open to traffic throughout construction, except for a short-term closure on First Street during specific phases of work. Traffic control measures will be in place, and delays should be expected. Construction activities will occur Monday through Friday, with City inspection staff on-site to oversee progress and ensure quality.

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.
