Making Roads
While waiting for a major California infrastructure bond program, highway contractors and engineers make due with some challenging projects.
By Greg Aragon
California highways are notorious for traffic. Since the
1960s, the total number of registered vehicles in the state
has increased from nine million to about 30 million and vehicle
miles traveled in the state have increased from 33.3 billion
to approximately 183 billion annually. And the Department
of Transportation expects a 35 percent increase in congestion
over the next 10 years.
"For too many people, gridlock has become a way of life.
We need to start work on our infrastructure," said California
Gov. Arnold Schwarzenegger, who unveiled a multi-billion Strategic
Growth Plan at his State of the State address in January.
"It's part of everything that's happening in California. Our
economy is growing, our population is growing and the demand
for infrastructure is growing. It's time to stop talking about
it, and do something about it. So I say build it."
The governor's plan, which would allot $107 billion in transportation
infrastructure improvement over the next decade, is designed
to address traffic problems by reducing congestion 18 percent
over the next decade and building more than 1,200 miles of
new highway and HOV lanes in congested areas and adding 600
miles of mass transit.

But until the state legislature acts upon the plan, commuters
must relay on previously funded major projects such as the
$490 million Garden Grove (SR-22) Freeway project in Orange
County, one the biggest project's currently under construction
in the state.
"This project is scheduled to be completed by Thanksgiving
2006, 800 days from ground breaking, an aggressive, but achievable
schedule," said Jim Laing, deputy project director, with
Granite-Myers-Rados (GMR), the project's joint venture design-build
team.
The 12.5-mile-long 22 Freeway is an east-west route linking
the 55, 57, 5, I-405 and SR-605 freeways in Orange County.
Along the way, the thoroughfare cuts through the cities of
Westminster, Garden Grove, Santa Ana and the City of Orange.
The project, which broke ground Sept. 22, 2004, consumes 12
miles of this length.
Construction consists of adding high occupancy vehicle (HOV)
carpool lanes and new auxiliary lanes in each direction of
the freeway, as well as the reconfiguration of the connector
ramp from southbound Orange Freeway (SR57) to westbound 22.
Other highlights include the widening or replacing of 55 separate
bridge structures; upgraded on/off ramps; and the creation
of 12 miles each of retaining walls, drainage pipes, and sound
walls (averaging 14 - 16 ft. tall).
Currently, the project's retaining walls are 80 percent complete;
30 of 33 new bridges are underway or complete; concrete paving
is well underway; and mainline traffic switches will open
several new bridges to traffic by this summer.
"The dryer weather this winter has allowed us to progress
the work faster than we expected the last three months,"
said David B. Smith, Area Manager for Granite's HCD Western
Regional office. "The majority of the structures work
is up and out of the ground now, and most of the embankment
work is complete, so we are less weather sensitive than we
were last year."
The GMR team is made up of Watsonville-based Granite Construction
Co.; Rancho Cordova-based C. C. Myers; and Steve P. Rados,
Inc., of Santa Ana. Design was provided by the GMR team through
lead designer, San Francisco-based URS Corporation, with support
from key local consultants, RBF Consulting of Irvine and Santa
Ana-based Wei Koo & Associates.
"We all have our separate expertise," said Rick
Grebner, program manager with OCTA. "Myers is an experienced
bridge builder, Rados is a highway builder and [Granite] does
both."
Other major highway construction projects include:
U.S. 101/I-405 Interchange Improvement
project. This Caltrans District 7 project extends
the current auxiliary lane on the northbound I-405 past
the off-ramp to the U.S. 101 connector and will also close
the loop on-ramp from eastbound Ventura Blvd. and construct
a bypass of the Ventura Blvd./Sepulveda Blvd. intersection
using Dickens St. The Sepulveda Blvd. on-ramp will be reconfigured
to separate the U.S. 101 connector on-ramps from the northbound
I-405 on-ramp. The city of Los Angeles's Sepulveda Blvd.
widening project is being combined with this project. Steve
P. Rados is the general contactor.
State Route 56/Ted Williams Parkway
Bridge Replacement project. This Caltrans project
will replace the bridge carrying the Ted Williams Parkway
over I-15 in San Diego. The bridge will be restriped to
two lanes in each direction and shifted to the north side,
or current westbound lanes, and the rest of the bridge will
be demolished and replaced.
State Route 4 Bypass project. A cooperative project with Contra Costa County and the cities of Antioch, Brentwood and Oakley, the bypass will replace existing State Route 4 from just south of the Main St. interchange to the existing intersection with Marsh Creek Rd.
