If it's not clear, 2 lanes come over the overpass towards where I shot the photo from. An offramp from 101 North terminates where the white pickup is.
This has always been a terrible merge. 2 lanes come across the freeway, and the offramp is a new 'added' lane, but the striping/bott's dotts between the #1 and #2 lane coming down from the overpass are virtually nonexistent. There are cracks in the road (the dark marks) where the lane markings should be.
It was always a big risk because cars in the right lane coming over the overpass used to just drift over into the offramp's new lane, and half the cars coming down the offramp didn't know they had a new lane, so they'd just STOP at the end of the ramp.
THEN the City, in its infinite wisdom, decided to fix none of these problems, but instead add a striped bike lane that cuts across the offramp. Absent lane markings to follow, drivers in the right lane would just follow the dashed bike lane and force themselves into the offramp's new lane. I witnessed at least 5 near collisions in the several minutes I was there taking photos.
They've since SOMEWHAT improved the markings between #1 and #2 lanes, but the bike lane markings are much more substantial and people still tend to follow them. Also, it still tends to confuse people using the offramp.
But this is an endemic problem; I bike commute and often a bike lane switches sides of a car lane in the middle of an intersection. It's the traffic version of "Step 1: right lane. Step 2: ??? Step 3: Profit!" Or "good luck, hope you come out on the other side of the intersection alive.
