Manteca is betting that four of a kind along the 120 Bypass will give them a winning hand when it comes to positioning for economic growth.Plans to build an interchange at McKinley Avenue and the 120 Bypass would give Manteca the equivalent of four aces in the hole as the city would end up with four interchanges that each would be a mile apart. That’s the minimum separation allowed by Caltrans design standards and the optimum to maximize access to prime freeway frontage commercial property.The Manteca City Council on Tuesday is expected to approve a cooperative agreement with Caltrans regarding the preliminary engineering and environment documents for the proposed interchange.The city is using $1.5 million in federal funds to do the initial work needed to move the interchange forward. The work is being performed by Rajappan & Meyer Consulting Engineers.
