Cahalan Street in SW Detroit

Used to stay at my aunts house on Cahalan btw Springwells and Mulane when I was a kid. Drove by there last week to see if the house was still there. Its gone, as are most of the houses on the north side of the block. Only two houses in the middle of the block remain. Seems odd that the south side of the block still has all the houses. There are some vacant/burned out homes in the neighborhood but not any where most of the block is gone. Just wondering if anybody knows about this. Thanks.
