I drove this interchange yesterday, and noticed that the eastbound I-10 sign, on 62 south, was once a westbound, with remnants of "WEST" and "Los Angeles" visibly having been demounted.
was this interchange rebuilt at one point? if so, when, and what was the original interchange configuration?
a look at the satellite image shows what may be the remnants of an at-grade T-junction, so my guess is at one point the freeway ended at CA-62, and there was a single high-speed ramp from 62 south to 10 west. that ramp was then later reconfigured to become the eastbound lanes, and a new westbound ramp was squeezed in, resulting in a) the odd ramp set where, from a southbound road, the east ramp is to the right of the west ramp, in contradiction to intuition - and b) the sign rearrangement.
any actual data to illuminate this, and either confirm or disprove my hypothesis?
