MacArthur Boulevard Southbound
Off-Ramp Improvement Project

The California Department of Transportation (Caltrans) proposes to modify the existing lane configuration on the southbound SR-73 off ramp to MacArthur Boulevard by widening it from one lane to two lanes. The proposed widening will allow for two through lanes from the off ramp onto southbound MacArthur Blvd. which is expected to reduce collisions. The purpose of the project is to reduce the severity and number of collisions at the project location by modifying the existing lane configuration and signalizing the off-ramp terminus.

The information in the Initial Study with Proposed Mitigated Negative Declaration is intended to disclose potential environmental impacts and propose avoidance, minimzation, and/or mitigation measures to reduce impacts associated with all project alternatives.

This project is currently in the Project Report and Environmental Document Phase.

The Public Notice is to inform you, the public, that the Intial Study with Proposed Mitigated Negative Declaration is available for your review. The public review period begins on November 22, 2017 and ends December 23, 2017.
