These replaced MV versions between 2019 and 2021. If anyone knows more about this type of light then I would appreciate more info (The LED versions that it not the Sequoia HPS versions).

Ok, looks like Caltrans have been busy retrofitting these.

These could be maintained by the city of LA rather than CalTrans as the overpass is above a city street. If an agreement is made, CalTrans can hand over maintenance of lights that they installed that light a city street over to a city.

Yeah maybe, they are actually replaced in all the underpasses down the road in the 2nd link.
