Question

Why are there street lights on a stretch of the I405 between Seal Beach and Long Beach, and not anywhere else?

Answer 1

Don't know.  I lived in Seal Beach and Long Beach. Can't say I ever noticed it.

Answer 2

Two reasons in my opinion. First, by Seal Beach Blvd., you have the military facility. They (the Navy) keeps the area well lit to monitor any suspicious vehicles stopped along the roadway.

Second, there are a LOT of transition roads onto and off of the freeway also lanes merging onto and off of the 605 FWY, so cal-trans probably feels the need to keep all these lanes well lit to help avoid accidents.
