Construction of Navistar International’s South Side plant just started in July, but the manufacturer already is shaking up plans for the $250 million facility: It will produce electric heavy-duty trucks in addition to the traditional diesel kind.

The shift comes as the Illinois-based company increases its bet that roads will teem with electric and autonomous vehicles in the not-so-distant future.

Navistar expects to start production in San Antonio in spring 2022.
