This interchange is a small cloverleaf interchange, which is inadequate for the task. There are severe weaving problems, and the 151 south to 90 east ramp has a very small radius. In 2001, this interchange will be rebuilt. It will include bigger radii for selected ramps, and also incorporate collector-distributor ramps for I-90. Also, a half-interchange will be built for High Crossing Boulevard, which is only about 1000 feet south of 151. Click here for the
plans, and here for the timeline and description.
