HWY 57/60 Interchange
C.C. Myers, Inc. worked with the City of Diamond Bar on the multi-faceted Orange Freeway-Route 57 / Pomona Freeway-Route
60 Direct High-Occupancy-Vehicle (HOV) Lane Connector and Collector Road project.
The HOV direct connector provides a safer and more efficient movement of traffic within this major freeway interchange,
creates a safer lane change system, and eliminates the crossing of three traffic lanes to access the connecting freeways and
HOV lanes.
The project included the realigning of the Grand Avenue on-ramp to westbound Route 60 by extending to Brea Canyon Road
and adding a new lane to the Grand Avenue off-ramp.
Napa Bridge
The Napa River Project consisted of constructing twin 1800 foot- long box girder bridges along Imola Avenue over the Napa
River, from South Coombs St. to Gasser Drive in Napa, CA. Also included, the construction of retaining walls, two concrete
slab approach structures, miscellaneous roadway improvements, and the demolition of the existing Maxwell Bridge over the river.
Work began on March 12, 2005 and was completed in early 2006, with a one-year plant establishment period to follow.
The biggest challenges on the project were the construction of four cofferdams in the river and the removal of the existing
Maxwell Bridge. The cofferdams were built to approximately 45' below the water level of the river and were constructed by
our subcontractor, Foundation Constructors, Inc. The removal of the existing Maxwell Bridge (a lift span bridge built in 1949)
was done with a 400 ton barge-mounted crane positioned in the Napa River. The crane removed the tower sections of the bridge,
the counterweights, and lift span, then lowered them to barges positioned in the river for transportation to a recycler in
Richmond, Calif.
Santa Monica I-10 Freeway
The earthquake damaged Santa Monica Freeway and its reconstruction provided the ultimate challenge to a contractor. Consider
the following:
Caltrans notified C.C. Myers, Inc. that they were invited to submit a bid on the project Monday, January 31, 1994, only
fourteen days after the Northridge Earthquake. Plans were available the night of the 31st with bids due less than four days
later, on Friday, February 4th at 10:00 a.m. The plans were preliminary and without details, the bid a fixed-unit price, multi-million-dollar
contract wtih a forty-percent disadvantaged business goal. C.C. Myers, Inc. was awarded the contract late that same Friday
afternoon.
Contract requirements allowed a maximum completion time of 140 calendar days with a penalty for late completion of $205,000
per calendar day and an incentive of $200,000 per day for early completion. Contract time commenced on Saturday, the 5th of
February, with materials and equipment moving to the jobsite that day and through the weekend. Even though the final construction
plans were not available until February 26th, C.C. Myers, Inc. immediately went to work on a 24-hour-day, 7 days-per-week
schedule with up to 400 workmen on the job, while maintaining a safety record that even surpassed C.C. Myers, Inc.'s AGC award-winning
program.
Sixty-six days after the contract was signed the freeway was opened to traffic, 74 days ahead of schedule. The opening
of the Santa Monica Freeway allowed over 350,000 vehicles a day to once again move between downtown Los Angeles and the Santa
Monica area. This effort saved costs calculated at over one million dollars to the public for each day the freeway was shut
down.
Despite numerous changes and unanticipated quantity overruns, the C.C. Myers, Inc. organization rose to the occasion to
meet this most difficult challenge in the full view and scrutiny of the public, the press and the politicians. The project
was acknowledged worldwide by industry and political leaders as an outstanding example of construction achievement.
WINNER: 1995 AGC Constructor Award Competition for Meeting the Challenge of a Difficult Job and Finalist in the category
of Contribution to the Community.
Route 80/Hercules
On January 19, 2006, Caltrans awarded the contract for Route 80 in Hercules to C.C. Myers, Inc. The contract work limits
were the Route 80 Corridor from Route 4 to the Cummings Skyway Over-Crossing.
The contract scope widened Westbound 80 and added a new 3.1 mile high-occupancy-vehicle (HOV) lane. To accommodate a new
alignment, the existing California Street Bridge was demolished and reconstructed and the Willow Street Bridge widened. Additional
work included the construction of six sound walls, a soil nail retaining wall, AC resurfacing, and modifications to the traffic
operation and lighting systems. C.C. Myers, Inc self-performed clearing, excavation, backfill, PCC paving, and all bridge
and structure work.
Work began in April 2006 with completion in October 2006. The major challenge was a 130 working days completion.
City of Berkeley Overcrossing
The City of Berkeley waited many years for a safe passage for bicycles, wheelchairs, and pedestrians to cross Interstate
80 from Berkeley's Aquatic Park on the East side of Interstate 80 to the shores of the San Francisco Bay on the West side.
This structure was needed to replace the narrow stairways, sidewalks and dangerous passage that existed for years at University
Avenue in Berkeley.
The new Pedestrian Overcrossing is a showpiece of engineering design. In crossing this structure, one experiences breathtaking
views of San Francisco, the Bay Bridge, and, most important to the City of Berkeley, the Golden Gate Bridge.
Foothill Oaks Blvd, Shingle Springs
C.C. Myers, Inc has constructed a new interchange at Highway 50 in El Dorado County to allow access to a gaming casino
being built by the Shingle Springs Band of Miwok Indians scheduled for opening in Fall 2008.
Construction included three cast-in-place, pre-stressed box girder bridges, eight concrete retaining walls and associated
other roadwork.
Benicia Bridge, Hwy 680/780 Interchange
In order to accommodate future traffic carried by the Benicia-Martinez Bridge, the existing Interstate 680 / Interstate
780 Interchange needed to be reconfigured. The Benicia project constructed new roadway alignments and bridge structures to
eventually switch all southbound traffic to the existing Benicia-Martinez Bridge, and to receive all northbound traffic from
the new main span. The Interstate 680 / Interstate 780 Interchange project included both ends of the spectrum in terms of
climate, terrain, geology, and construction.
Carquinez Bridge Approach Replacement
C.C. Myers, Inc replaced the 1958 bridge approach deck. Work started September 26, 2005 and was completed in November 2005.
The work consisted of removing and replacing approximately 110,000 square feet of concrete deck. In addition to the deck replacement,
CCM constructed a seismic expansion joint that will be used for research and development of the seismic expansion joint installed
in the new east span of the Bay Bridge.
