Dewitt Avenue "S" Curve Roadway Realignment Project, Spring Avenue to Origilia Lane

Project Background​

Dewitt Avenue is an arterial roadway providing a connection between the City of Morgan Hill and Community of San Martin. Over the years, the “S” curve portion of Dewitt (project location) has been the scene of accidents, injuries and property damage. Various traffic devices have been installed to provide advance warning and reduced speed limit but the number of accidents has not decreased.

Project Description

The project consists of roadway realignment to eliminate the “S” curve portion of Dewitt Avenue located between Spring Avenue and Origilia Lane in the City of Morgan Hill, California. It will result in a roadway that is straighter and flatter in grade with shoulder and wider for bicycle use. By realigning the existing “S” curve, the new alignment will improve the line of sight and traffic safety for drivers, bicyclist and residents using Dewitt Avenue.

Right of Way Acquisition and Utility Relocation

The County has completed acquiring right of way from five property owners. The new alignment will require utility (electricity, phone and water main) relocation, some prior to and some during the realignment construction. Homeowners will be notified by PG&E and Verizon on the work schedule.

Project Award

The project was awarded to Granite Rock Company last November 15, 2016 at a cost of $2,165,013.00.  The entire project has a duration of 150 working days or approximately 7 months, weather permitting.  Notice to proceed issued last January 13, 2017.  Due to wet winter conditions, the project started April 24, 2017. 

Construction Schedule

Final Inspection Dec 21, 2017. Project is completed.


Traffic Impact and Road Re-Opening

The re-aligned Dewitt Avenue roadway between Spring Avenue and Origilia Lane was re-opened to public traffic last November 14, 2017.
