SILER CITY, N.C. (AP) — At the epicenter of President Joe Biden’s promised economic boom, a slow tractor can still halt traffic.

Just 81,000 people live in rural Chatham County, North Carolina. There are 1,076 farms. The old mill now houses a dance studio, a grocer and a steakhouse. For work, many people have no choice but to commute to nearby Chapel Hill, Durham and Raleigh.

But after years of careful planning, Chatham County has started to change.

The new Wolfspeed factory — six football fields long — overlooks I-64 and will soon produce advanced wafers for computer chips. Automaker Vinfast is scheduled to open a factory as well. Both projects stem in large part from incentives that Biden signed into law.

Developers, including the Walt Disney Corp., plan to build several thousand new homes.
