Project Alternatives

The following are the four project alternatives that will be further analyzed during this effort.

- No Build

The No Build alternative reflects future conditions along SR-55/Newport Boulevard with no major improvements. This alternative also provides a “baseline condition” to which the other alternatives can be compared.

- Transportation System Management (TSM)

The TSM alternative includes improvements, such as signal timing and bus turnouts, that can be made without significant impacts to properties and at a lower cost than the build alternatives.

- Elevated Turn Lanes

The Elevated Turn Lanes alternative features improvements to both ends of the study area. Some of the concepts under consideration will include vertically separating turn movements from 17th and 19th Streets to SR-55/Newport Boulevard, thereby increasing capacity along the corridor.
 

- Cut and Cover

The Cut and Cover alternative evaluates building a new structure below Newport Boulevard. This alternative proposed a four-lane extension of the Costa Mesa Freeway under SR-55/Newport Boulevard from 19th Street to Industrial Way. Newport Boulevard could be reduced to a six-lane arterial with enhanced medians, parkways, and wider sidewalks. This alternative is designed to separate local traffic from regional through-traffic.
