Lane Lights Mean The 110 Freeway Goes Both Ways
Surely you have noticed the cool new blue lane lights on the 110 Freeway delineating the transition lane to the 5 North (see a video embedded below). The lighted pavement markers, or Smart-stud systems, are a way to finally stop all of those jerks from sneaking into the front of the line when we have all been waiting patiently in line for the 5 North like good citizens. Plus they make your night-time drive more psychedelic, like you are at the laserium.
According to Inside Seven, the Caltrans newsletter, the plan is to make lane 2 a lane that can be used two ways, what they call a "dynamic" lane.
As part of this system, lighted pavement markers, or Smart-stud systems, will be used to guide and enforce the use of lane Number 2 as an optional lane. The Smart-studs will be placed between lane Number 1 and lane Number 2 as delineators. During peak hours, the lighted pavement markers will be turned off, thus allowing motorists to use lane Number 2 as an optional lane for northbound SR-110 mainline or to the northbound I-5 connector.
So when the lights are off, you can either stay in the number 2 lane and continue North on the 110 or connect to the 5 North. According to Judy Gish of Caltrans in a recent phone interview, they will be extending the number 2 lane so that it goes around the curve. There will now be 2 connector lanes to the 5 North. There is enough room to add the second lane without having to widen the freeway, which would be structurally unsound. And it would suck, because that spiral cement staircase is so badass.
