Project Overview:
FCI South
constructed a new six-lane freeway to freeway interchange
for California state routes 94 and 125. The $62 million Caltrans
project was located in the cities of Lemon Grove and La Mesa.
This project used the cast-in-place method which involved
first building large wooden forms, adding rebar to these forms
and pouring concrete to create the foundation of the bridge.
Columns were drilled into the ground 60-70 feet and in some
cases, rebar was inserted into the rock and then spread, providing
additional support. This project was completed in March, 2003.
