I-15 Express Lanes Construction Update - Week of August 26
15 PROJECT GIRDERS ARE "ON THE GO"
The heaviest concrete girders ever to be made in California will be "on the go" during the next few months, traveling at night from Perris to the Santa Ana River Bridge in Norco.
Crews will widen the massive Santa Ana River Bridge using 55 girders, some weighing more than 132 tons and measuring 175 feet long. The girders will make a three-hour trek with CHP escorts on southbound I-215 to westbound Murrieta Hot Springs Road, and then on northbound I-15 to Norco, a distance of about 61 miles.
The girder transport will occur intermittently on weeknights during off-peak hours, beginning at 1 a.m. Motorists can expect short traffic breaks and lane closures over the next few months until all 55 girders complete their journey to the project site.
