Project Overview
The City of Elk Grove (City), in coordination with the State of California Department of Transportation (Caltrans), is currently planning a new interchange at Whitelock Parkway and State Route 99 (SR-99) as included in the City’s General Plan. The new interchange project (Project) will help to address the expected increased traffic demand due to existing residential growth and planned future developments near Whitelock Parkway. A bike and pedestrian overcrossing of SR-99 is included in the Project and auxiliary lanes connecting to the new interchange are being considered. Also included is the realignment or modifications to East Stockton Boulevard and widening of Whitelock Pkwy. The Project includes environmental clearance of high occupancy vehicle lanes on SR-99.
Project Scope
The Project will construct a new interchange connecting Whitelock Parkway to State Route 99 (SR-99) between the Elk Grove Boulevard and Grant Line Road interchanges. The Project also includes consideration of auxiliary lanes of SR-99 to improve traffic operations. In addition, the Project will provide a new bicycle and pedestrian connection to Elk Grove Regional Park.
The Project also includes improvements to the local roadway network associated with the Lotz Parkway and Promenade Parkway Project (WTR096) to support access and circulation in the surrounding area.

Project Background
As the Project directly connects to an existing Caltrans managed facility, collaboration and approval by Caltrans will be required throughout all phases of the Project. The first phase for this type of project is the Project Initiation Phase, which resulted in the completion of a Project Study Report - Project Development Support document (PSR-PDS). The purpose of the PSR-PDS is to identify and estimate Project scope, schedule and support costs necessary to complete future studies and work needed during the environmental phase. The PSR-PDS for this Project was approved on August 9, 2020.
Current Phase
With the PSR-PDS completed, the Project has entered into the next phase which is the Project Approval and Environmental Document Phase (PA&ED). The purpose of the PA&ED phase is to analyze and refine alternatives and perform the necessary environmental studies, with the end result being an approved Project Report and California Environmental Quality Act (CEQA) environmental document. The lead agency for CEQA compliance is Caltrans.
Schedule
Funding Strategy
