Cranes, Trains and Automobiles (on I-5 South Corridor)

Motorists driving northbound on the Santa Ana Freeway (Interstate 5) from Orange County can see and feel construction activity gearing up on the I-5 South Corridor from Valley View to Rosecrans avenues through La Mirada, Santa Fe Springs and Norwalk.

Motorists also may be feeling a bit more squeezed, firstly, by the congestion, secondly by k-rail (concrete barriers) in the center median and in place of a right shoulder, and thirdly, visually by the sight of large construction cranes situated so close to the freeway. The Los Angeles/Orange County line has experienced bottleneck congestion for years as the numbers of lanes at the county lines do not match-up.  Now, that’s all about to change with the I-5 South Corridor Improvement Projects, a 7-mile corridor construction project from the Los Angeles County/Orange County line to I-605.

The work taking place includes freeway widening to accommodate one HOV, or carpool lane, and one general purpose lane ramp, bridge and interchange reconstruction and reconfiguration, shoulder construction and widening, concrete median barriers and safety enhancements.

Please be aware that there are two cranes at work on the I-5 South Corridor:  one on northbound I-5 at Alondra Ave/North Fork Coyote Creek Bridge (between Valley View and Carmenita); the second crane on southbound I-5 at Carmenita Road. Cranes usually mean that noisy work– usually involving pile driving - is taking place. Currently, Caltrans is working to widen the Alondra Bridge and the Carmenita Bridge.  Very soon, the Shoemaker Avenue Bridge will also be widened.

If you commute daily by travelling on northbound I-5 from Orange County and points beyond, please consider hopping aboard a Metrolink train ( for your commute into Downtown Los Angeles at Norwalk, Buena Park, Fullerton, Santa Ana, Anaheim, Orange, Irvine or stations further south.  Three of six I-5 South Corridor segments are now in construction.  The other three will begin in 2013 and are estimated to complete by late 2016.
As Caltrans is working to widen I-5, our best advice during the next three or four years of construction is to plan your commute, allow extra travel time and for timely, accurate and accessible real-time traffic information and travel times, visit Caltrans Quick Map call  Metro’s 511  or visit   or
