This interchange is a cloverleaf interchange. Weaving problems exist in every direction and high traffic volumes on Interstate 90/94/39 create merging conflicts. 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 southeast of the 151 interchange on 90/94/39.
