The California Department of
Transportation (Caltrans) is preparing a project study report to identify ways
to relieve freeway congestion along the Santa Ana Freeway (Interstate 5)
between the Costa Mesa Freeway (State Route 55) and the Orange Freeway (State Route 57) in Santa Ana. The study is looking at ways to
increase capacity and improve traffic flow through this section of Interstate 5
(I-5) that connects four major freeways in central Orange County. The study is
expected to be completed in late 2009.
The Orange County Transportation
Authority (OCTA) selected a consultant to begin preparation of an environmental
document for improvements along I-5 between Avenida Pico and Pacific Coast Highway, through the communities of San Clemente
and Dana Point. The environmental study will evaluate the benefits of extending
the current high-occupancy vehicle (HOV) lanes on I-5, that presently end at
the Pacific Coast Highway interchange, all the way down to Avenida Pico in San Clemente.
Environmental approval is expected
in mid 2012.
OCTA is also preparing a project
study report to evaluate options to improve the I-5/Avenida
Pico interchange. The study will look at ways to improve local traffic flow
entering and leaving the freeway in this area. This study will be coordinated
with the environmental study being done for the I-5 HOV lane project in the
same vicinity. The study is expected to be completed in late 2010.

The South Orange County Major Investment Study
concluded with recommended strategies and improvements to address
future demands on our transportation system. The locally preferred
strategy was approved by the Board in October 2008 and established the
M2 freeway plan as a priority for improving transportation in south
Orange County followed by additional proposed improvements to I-5 and
I-405.
The 1st Quarter of 2008 was a very active period in the development
of Renewed Measure M highway projects in Orange County. Work was
underway on all nine freeway corridors that were targeted for immediate action under the M2 Early Action Plan. The work on freeway projects this quarter included
the advancement of four conceptual design reports, four environmental
documents, and three final designs. This work will set the stage for
the eventual construction of 40 miles of freeway improvements, costing
over $1.5 billion, over the next ten years.
At the end of 2008, improvements to 45 miles of the county’s freeway
system will be underway. In addition to the projects outline by the
Early Action Plan, the Board has approved a revised implementation plan
for the San Diego Freeway (I-405) West County Connectors projects. Work
is also underway on the Santa Ana Freeway (I-5) Gateway project and two
other state-funded projects on the I-5 in south Orange County.
