Interstate 10 is no stranger to damage or political attention

If any freeway is a cultural icon, it is Interstate 10, which stretches more than 2,460 miles through eight southern tier states, from the Pacific Ocean in Santa Monica to the Atlantic in Jacksonville, Florida.

Its iconic status is especially evident in Southern California, where it is known by several names as it runs through the heart of the Los Angeles metropolitan area, carrying 300,000 vehicles a day.

To those who continue the region’s tradition of naming roadways, it’s the Santa Monica Freeway. Traffic reporters refer to it as “The 10.” At one time, there was even a serious movement for Christopher Columbus – before, of course, the explorer became politically incorrect.

By any name, I-10 is an important artery for a region that still depends on autos and trucks to carry people and goods. Its vital role makes it, from time to time, a political lightning rod.

The freeway’s biggest political brouhaha erupted in 1976, when the pavement of one lane in each direction was marked with diamond-shaped symbols and reserved for cars carrying at least three passengers – the state’s first experiment discouraging single-occupant driving. The immediate result was traffic chaos both on the freeway and on nearby surface streets and countless angry drivers.

Although the so-called diamond lanes experiment had been planned during Republican Ronald Reagan’s governorship, Jerry Brown was governor when Caltrans made the switch, just as he was launching his first campaign for president.

Nevertheless, it reflected Brown’s philosophy. “Obviously,” he said that year in a speech, “the ethic of unlimited freeways that attempt to pour cement from one end of the state to the other is over and it takes a while for people to adjust to that.”

Adriana Gianturco, an old college friend of Brown’s who had been an urban planner in Boston, became Caltrans director the same day and had nothing to do with the project, but immediately became its much-despised symbol.

Five months after the diamond lanes experiment began, a judge ruled that it had not undergone a needed environmental impact review and with opposition still raging, the Brown administration quietly dropped it.

Eighteen years later, in 1994, I-10 once again became the center of political attention when the Northridge Earthquake seriously damaged the elevated structure. Although many other public facilities were also damaged, I-10’s central role made repairs a priority.

Then-Gov. Pete Wilson declared a state of emergency and the state hired a construction firm from the Sacramento area, headed by a larger-than-life builder named C.C. Myers, to rebuild the freeway with huge financial incentives for rapid completion. Myers’ crews worked around-the-clock and finished repairs 74 days ahead of schedule, earning a reported $200,000 a day bonus. The tab doubled from $14.9 million to $30 million, but it was worth it since closure of the freeway was costing the local economy an estimated $1 million a day.
