SR 99 Widening in Gridley
What is the Project?
Beginning in 1965, improvements have been made to widen State Route 99 with the incorporation of a continuous two-way left turn lane south of East Griddle Road and north of Spruce Street.   Some improvements have been accomplished at the Spruce Street/SR 99 intersection (1983).  No improvements have been pursued at the SR 99 intersections of Hazel Street and Sycamore Street.  For several years the City of Gridley and BCAG have requested the widening of State Route 99 through various proposed alternatives.

A Project Study Report (PSR) (April 2000) was prepared under the direction of former Gridley City Engineer Ray D. Rolls, investigating the alternatives for widening SR 99 from East Gridley Road to Spruce Street.  Improved safety and operations together with reduced congestion are the goals of the proposed project.  Of six alternatives proposed, the preferred was identified as being the one that improves the highway to a full five lane facility with a continuous two-way left turn lane being the fifth lane.  This alternative matches the facility geometry both north and south of this two block section of SR 99 through the City of Gridley.

In November of 2001, BCAG took the lead to develop the environmental document and begin the process of completing the first phase of this project which is the Project Approval and Environmental Document (PA&ED) phase.  

Why is the Project being done?
The necessity of this project is driven by operational and safety considerations.  The primary problem is vehicle and truck left turn conflicts onto and off of SR 99, particularly at the Sycamore Street intersection, in combination with adjacent intersection backups and apparent lack of traffic signal coordination.  Due to the relatively high volume of through traffic, this problem exists at all times during the day and is particularly bad during the AM and PM peak hours. 

What is the current status of the Project?
The Mitigated Negative Declaration was approved by the BCAG Board of Directors in March of 2003. This completes the California Environmental Quality Act (CEQA).  The National Environmental Policy Act (NEPA) Categorical Exclusion was completed in August of 2004 and the Project Report signed in September of 2004.  

The design consultant is currently developing the plans for the development of the construction project for a total estimated construction cost of $4.2 million dollars.  The project will build the roadway to a five lane facility and coordinate the timing of the traffic signals with a new traffic signal installed at the Sycamore Street intersection.  Caltrans is currently acquiring the right of way necessary for a construction project to begin in the Spring of 2009.
