The city of Meadows Place, a small city bordering Houston, Stafford, and Sugar Land, is planning on installing a series of four roundabouts on S. Kirkwood between W. Bellfort and W. Airport. They will replace the four stop signs within 300 yards of each other within the neighborhood. They are being billed as a traffic calming measure as S. Kirkwood runs through a residential neighborhood. The traffic along S. Kirkwood in that area is static and not expected to grow any. They will be reducing the road from four lanes to two lanes in the area so they are able to fit within the right-of-way. You can see more about it here.
