Hi, My son recently took his driving test and came upon a newly configured intersection that he was not familiar with. The NB-SB road (Chestnut) originally was a two-lane road, but was recently reconfigured to include bike lanes and a TWLTL on the south leg. The driving test requires him to travel NB on Chestnut and turn left onto Eight, which he had done many times before the intersection was reconfigured. Unfortunately, for the driving test, the newly reconfigured intersection with the TWLTL confused him, and he ended up making the left turn onto Eight from the NB thru lane. The proctor failed him immediately and said he made the left turn from the wrong lane. :(

I thought that was a little harsh. I also think the intersection design is a bit odd since there’s so many opportunities for head-on conflicts. For example, a NB left turn vehicle could come into conflict with a WB left turn vehicle that decides to use the TWLTL. There are no driveways along the SE corner of the intersection so why extend the TWLTL all the way to the intersection. Maybe they want better flow for NB traffic, but there’s not a lot of NB LT traffic so couldn’t they have just installed a dedicated NB LT lane?

Has anyone seen a design like this before?
