Answer: I know several universities are researching salt-tolerant turfgrasses but so far, there are none available. However, here are a few ideas: You can create a flower bed, and grow annual flowers along the roadside. Nasturtiums, for example, thrive in hot, dry, relatively infertile sites. You'd need to start with new seeds or plants each year. You might try a few exceptionally durable perennials, such as yarrow, gallardia, and sedum. Also Roman chamomile (Chamaemelum nobile) and evergreen candytuft (Iberis sempervirens).
Best wishes with your landscape.
