Have you considered pachysandra?

I think the road salt might fry it in the winter. It's a main road so they salt it quite a bit. Anything evergreen might get burnt, which would rule out junipers as well -- my bad.

But thanks for the thought.

Lilies of the Valley?
Columbine?
Hostas?
Periwinkles / myrtle?
Spanish Bells?

Just some suggestions

Don't know how it would handle salt, but THE plant for low maintenance and dry shade is Geranium maccrorhizum, Big Root Geranium. Handsome and semi-evergreen.

I don't know what it does during the winter in your zone but Heuchera (Coral Bells). I have it growing in a very shady location under a blue atlas cedar and pretty much ignore it and it does surprisingly well. Whenever it rains, it gets a growth spurt. The leaves come it many different colors too but I've found the common green do best.
Also Vinca minor would do very well & gets pretty flowers but might be invasive so check on that first.
Another that would do well is Ivy~ I don't know if the variegated is as invasive but even if you mulch, you're going to get weeds so I'd plant something.
