Abstract: The weaving free two level cloverleaf type local interchange for a highway crossing under a street accommodates traffic from a plurality of traveled ways which include a first traveled way for traffic traveling in a first direction, a second traveled way for traffic traveling in a direction opposite to the first direction, a third traveled way for traffic traveling in a direction intersecting the first and second traveled ways, and a fourth traveled way for traffic traveling in a direction opposite to the traffic traveling on the third traveled way. The first and second traveled ways cross under the third and fourth traveled ways. Each of the first and second traveled ways has a design speed compatible to a highway or freeway design speed, or is designed according to highway or freeway design standards.
