Plans call for Manteca’s fourth interchange on the 120 Bypass being pursued at McKinley Avenue to be the city’s first partial cloverleaf. But in order to save money the city is considering an option that would allow the interior loop onramps to be built at a later date. That means the initial construction would have all left turns from McKinley Avenue to 120 Bypass onramps go through signalized intersections just as they currently do at the Airport, Union, and Main interchanges.
