Project Overview:
FCI South
provided construction services on five highway widening projects
with a constructed value of over $165 millio and a total of
six highway milesn on Interstate 5 in Orange County. These
Caltrans projects encompassed widening I-5 from the existing
6 lanes to 12 lanes, including four high-occupancy vehicle
(HOV) lanes. The first project began in December of 1996 and
work was completed in late 2000.
Project Features:
Six miles of roadway reconstruction, widening the existing
highway from 6 to 12 lanes
Six existing freeway overcrossing bridge structures removed
and replaced
Nine new bridge structures constructed with cast-in-place,
prestressed box girder bridges
Two new cut and cover tunnel structures at Disney Way. The
tunnel, founded on 919 steel piles, contains 9800 cubic yards
of concrete and sports colorful ceramic tile on its interior
walls
32 reinforced concrete retaining walls
30 masonry soundwalls
15 mechanically stabilized earth walls
Interesting Facts:
Reconstruction of the Santa Ana River Bridge involved building
the substructure during the summer months only. Superstructure
constructed of 198 precast girders, which were all set at
nighttime
Construction performed within ten feet of a large office building
Extensive shoring required to protect existing structures
and roadways
Significant underground construction required interacting
with private owners and maintaining traffic during construction
Shoring at the abutment of an existing railroad bridge to
allow construction of a new railroad bridge. Tracks remained
active during construction
Minimizing traffic impacts as construction was ongoing through
the most popular tourist area in Southern California
